http://www.２L.no can get dsd File but this is just sample. so please try to make dsd file from PCM .then use TASCAM Editor TEAC TASCAM DSDthis is Link ,would you visit TEAC TASCAM SITE.

So easy to get DSF file from PCM

https://github.com/np1/mps-youtube
youtube player by command line ,can down load music.too enjoy,
#apt-get install python-pip mplayer
# pip install mps-youtube
# pip install --upgrade pip
# mpsyt
try to test first,,,install

Install YMPD on NanoPi Neo2

doing watch ympd by Fedora Core 22 Linux x64 ICEWM

apt install cmake
apt install libmpdclient-dev
apt install libssl-dev
apt-get install gcc
apt-get install g++
------
cd /usr/lib
git clone https://github.com/notandy/ympd
cd ympd
mkdir -p build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX_PATH=/usr
make
make install
------
then write command line /usr/lib/ympd/build/ympd &
nano /etc/rc.local then edit, add above line /usr~
therefor automatically start ympd when reboot Nanopi-neo2 server.NanoPi-Neo2 smallest server can control by ympd instantly by other PC.
" http://nanopi-neo2.local:8080 " can see NanoPi small server. NanoPi-Neo2 is depend on which did you made server name ever.
can reproduce any kind of format as dop= PCM ,even dsd 5.6Mhz 2.8Mhz too but must be upgrade mpd 0.20 because this version is 0.19
but be careful to make update mpd.
Note : must be add additional command is write before "exit 0 " at /etc/rc.local

cantata(gmpc too) can do listen Music by Virginia Music and all of WEBRADIO Virginia Music's pls

work fine as I2S DAC on 15th Oct 2017

PCM5102a I2S DAC DIY Testing SkyMPC with Cantata

No more USB DAC, Sound is quite good ,play DSF is nothing problem with 5.6 Mhz as DoP :)

Large Scale Just need Master Clock same as Raspberry pi

Raspberry pi Zero with I2S DAC

root@NanoPi-NEO2:~# cat /proc/asound/card0/pcm0p/sub0/hw_params
would you enter this command above line.. probably indicated 16 bit so you are listen music 16 bit.not dsd even High Reso,
if indicated what to do......?
NanoPi-NEO2:~# cat /proc/asound/card0/pcm0p/sub0/hw_params
access: RW_INTERLEAVED
format: S16_LE
subformat: STD
channels: 2
rate: 44100 (44100/1)
period_size: 4410
buffer_size: 22050
This is I2S out put by PCM5102a so 16bit sound.problem of alsa.
But sound is quite very good.please try build up one of NanoPi-Neo2 or other version.

new I2S DAC for Nanopi-Neo2

Master Clock 2mm x 2.5mm very small Xtal by SeikoEpson SG-210STF

mount.cifs //192.168.1.12/NAS /mnt/NAS -o iocharset = utf 8
Let's also access volumio 2, it is mount first. Please make mkdir /mnt/NAS in advance. I get the file below the NAS of volumio 2, but this does not work very well,
NAS The following is a shared file of micro servers connected to other LAN. This will not work. I can see the directory, but I can not get permission.
Although you can read the file that exists in Volumio 2, it does not work very well, although a small music server is connected in the room separately, the purpose is to listen to the music throughout the year
Since it is used as a spare or file server when somewhere goes down unless it is running multiple times, multiple servers are required. Output selector by music category
Switch by. I am doing such usage.

Note: The above mounting method must be mounted each time it is started up, but there is also a way to put it in /etc/fstab, this practice is also dangerous on x86 Linux and will not start up.
Since this is a fatal defect in this server without X, we think that it is a good idea to start up each time if possible. There is no better way to relieve. People who are confident of Linux should try it.
Although this is also an experience, it is a drawback of a server that can be accessed only by SSH.

The control recommends SKYMPC, it has very useful control function.

There are functions such as "update" and "MPD connection" among the functions of SkyMPC. If an error occurs, use ssh to repair the Nanopi Server.
If there is no error in SkyMPC
It is OK. Then use other clients to monitor, select tunes and select songs. I think Cantata is very good

# apt-get install cifs-utils
then
# mount.cifs //192.168.1.12/NAS /mnt/NAS -o iocharset=utf8 This is the address of the Volumio 2 in the house, but you can see inside, but to extract
I can not, Volumio 2 contains thousands of music on hard disk of 1 Tera HDD USB (SATA) attached to Volumio 1.55 (192.168.1.6), but this Volumio 1.55 can be accessed directly Without
It is a library of Volumio 2 (192.168.1.12). So I would like to access from NanoPi - Neo 2, but I can get permission, but I can not see the inside.

root @ NanoPi - NEO 2: ~ # ln -s /mnt/NAS/Music /var/lib/mpd/music/Music
root @ NanoPi - NEO 2: ~ # ln -s /mnt/NAS/USB_Music /var/lib/mpd/music/Music

After doing it, if you symbolically do it, the contents are visible and it comes to the image shown above.
Because I keep it all the year round, I think that mounting should be done when starting up manually. Automatic startup
I think that it is good manually because there is a possibility that it will not move.
With this you can read thousands of songs of music with NanoPi - Neo 2. 64G Byte of music is enough, but the information on the hard disk is
We recommend this method because it will not erase by mistake.
Note:this part use Google translation,from Japanese to English.I am so sorry about lazy thinking... :)
From the long experience of Linux on NAS information in etc /fstab If you put mount information on NAS side there is something wrong Linux will not start up.
Therefore, it is safer to input the mount information from the command line as necessary.
If there is a problem on the NAS side, it will be displayed as an error, so you can solve it by setting up the NAS side. Most are errors on the network.
In the case of NanoPi-Neo2 　I think that it is better to repair errors in this way because there is only repair means for SSH.
(translation by google English from Japanese,translation is something odd by google but enough to understand for people who would like to know....I guess)

Now Can do play Music of other side of files by NanoPi-Neo2 ,Hilary Hahn plays

Sound is Normal,mcuh better PCM5102A 's sound charactor,

Evaluation: Well, an ordinary sound came out, the DAC of the PCM 51XX family is also the same,
but it is more intuitive to remove the 4700 pF capacitor for the output filter.
How about DSD 2.8 Mhz 5.6Mhz are normal but DoP as PCM.
Crystal use has default specification.in my case need to use 50 Mhz crystal unit.
PCM 5102A also uses the output capacitor and uses it, but my ears feel that PCM 5102A is better, apart from S / N.
The sound of the PCM 512X is also PCM5102A　.It is the same tendency sound.
If you set the capacitor (capacitor) that drops to the ground to a large value,
there is a tendency that the sound will be muffled.
If you need CR there, increase the series resistance and increase the value of the capacitor
We recommend you to reduce the size. Since this is also considered to determine the frequency of cutoff,
it is usual that the frequency is determined by F = 1 / pi x C x R. If it is made smaller, the cut frequency becomes
We will go up so let's consult with your ear and decide the value here. After all it seems that deletion is the best.
Equipment without a capacitor in the output is internally complementary, so to be differential
It is normal to have it, and if the balance collapses, the minus or plus voltage comes out to this part,
so there is a possibility that the amp attached to it will break down.
These are digital stores .This is the DAC and preamplifier I thought of. Let's attach a coupling capacitor.
In the world of vacuum tube amp it is a general design not to use fixed bias when using an expensive vacuum tube.
It is also common that the input circuit contains a transformer or a condenser. When there is a CR,
be sure to calculate and decide the value. DAC such as PCM5102A is enough for me, but I made it before
The DAC with SPDIF input using FN 1242A is the best, you can listen to it calmly.DSD are play as DoP .(this part translated by Google)
If do you have I2S DAC by PCM5102A like HAT.does not need special set up for this I2S DAC.
If you make your own, you can make one with the same performance as HAT on the market with less than USD 10 dollars.
Looks are not so good, but the performance is the same. :) !
About ES9023 and FN1242A are just same kind of sound .very similar.just need audio_out for es9023 for mpd.let' me know.if correct wrote
audio_out suppose will be get good sound.I have to test.



I used it for several hours In the case of a vacuum tube ES9023 is like a 300B single-ended Amplifier
and PCM 5102A is like a 2A3 single-ended Amplifier. How about that? It is such feeling.

few days later I could'nt make contact with the other Music server after update and upgrad.. then some site said have to add option vers=1.0
After that, communication began to catch from around mid-November 2017, it got caught and it became impossible to link with other servers. Soon there will be no sound, just a file server
I got it. I installed smb.conf mpd.conf in front of another server's HDD before installing it again. It was also several degrees, I thought, mpd is difficult. that too
Up Date, Up Once we grade it, we are no longer standing up. I installed it again, but other servers could not recognize it. There was a reference example when looking at Qiita.com.
If you add version = 1.0, for example, mount.cifs //192.168.1.12/NAS /mnt/NAS -o vers = 1.0 iocharset = utf8
[vers = 1.0 is] additionally entered.NAS after IP is one of directly of other Music server.please use SKYMPC for seach other Music server and Windows Share.

Volumio 2 for NanoPi-Neo2 will coming soon ???

Coming　soon ,,,I guess... Not GNU but ???,,,,,

Still No Sound from USB(SPDIF) and Saber ES9023 any mode,and no reboot and shutdown ***REF*Volumio for Nanopi2

We are not going to struggle, but in this forum there is a comment that thinking that switching databases sounds. The last ZIP is about to enter. Download the previous Volumio 2-NanoPi-Neo 2
Burn to micro SD. Please set this so that it matches the environment once it is set up. I will reboot. In the case of NanoPi-Neo 2 I am not steady here and will not reboot, so please switch off.
take out the micro SD and look at the boot on the main PC. I think that you can see sun50i-nanopi-neo2.dtb. Unzip the newly downloaded file sun50i-h5-nanopi-neo2.zip to this
Rewrite this file with the same name. So, it is the current state that I started up. Sound from DIY's Saber ES 9023 came out. It is a very good feeling. This made the threshold very low. I can not do ribs etc
I think that trouble will somehow come about. About switchable This one-board PC does not have a power switch, so a USB adapter with a switch or an AC socket with a switch etc
Currently available anywhere at a very low price. Use this as a power switch. Self-made Saber ES 9023 made a powerful sound.
(Traduction by Google from My bad Japanese)
So, you can do these without needing special Linux knowledge apart from launching. Volumio sounds bad
I am told, but this is enough for me. The sound is the destination of the DAC, the general theory is that it is an amplifier or a speaker.
I listened to lots of high-end machines with very good sound even with 16 bit DAC.I knew.

Getting Good Sound from NanoPi-Neo2 by Volumio2 on 3rd Dec 2017

DIY I2S DAC ES9023 with 300B Single Ended Amplifier

Edited mpd.conf of Volumio NanoPi-Neo2....a part of audio_out is empty escript
format "*:*:2"
so replaced "*:24:2" then reboot I got sound of DSD, DSF ,,,very clear sound.can play any kind of Music from NanoPi-Neo2 by Volumio2 now.
still on 30th Dec 2017,Volumio2 for NanoPi-Neo2 is un-stable.

audio_output {
type "alsa"
name "alsa"
device "softvolume"
dop "yes"
mixer_device "SoftMaster"
mixer_control "SoftMaster"
mixer_type "software"
format "48000:24:2"
}

It is the world's smallest music server, you can get high-quality sound with a good DAC. Much lower price.

Sound is very clear and very good musical sound getting from NanoPi-Neo2 by Volumio2

How to add other webradio by hand at Volumio2:just open vi or nano, /data/favourites/my-web-radio
[{"service":"webradio","name":"Smooth Jazz NYC","uri":"http://streaming308.radionomy.com:80/SmoothJazzNewYorkCity"}]
[{ data }] {data} is web-radio-data just like above.off course you can add on gui volumio menu.

######################################################

Finally I got volumio2 Nanopi-Neo2 latest version Just install and detect ES9023 DAC .nothing problem this version is Volumio2.0-2017-11-26-arm7-nanopi2.img.7z
from same forum link.please read and get new archive.show next demo.but if your house has optic line, please use 1G speed of hub for connect Music Server.
as Very nice mini Music Server you can build up and not expensive.is Volumio2 by NanoPi-Neo2 .but un-stable

Volumio2 by NanoPi-Neo2 Volumio2.0-2017-11-26-arm7-nanopi2.img Froze when DSF play ,flac ,mp3 are fine

some friend send me LP to flac file by google strage ,,flac,mp3 even mp4 sound are fine and very clear

Watch from Cantata under Ubuntu Xenial by Rasp P3

From the viewpoint of operability, Ubuntu that installed mpd seems to be the best. If you use cantata or skympc you can quite go back to the library and WEBRADIO etc,
If you use the function in Cantata you can choose music and tuning freely. The sound also improves considerably by editing mpd.conf. The archive underlying any distribution
Since it is mpd, the things to do are the same, so I think that it is good to refer to the editing sample of mpd.conf of the other distribution. SKYMPC can see a fine extension
I can do it, and you can play DSF, DFF etc. I think this is enough.

Step by Step install mpd Music Server into NanoPi-Neo2

(1) get Ubuntu Xanial for NanoPi Neo2 nanopi-neo_ubuntu-core-xenial_4.11.2_20170605.img.zip
(2) nanopi-neo_ubuntu-core-xenial_4.11.2_20170605.img.zip roast by 16G Byte micro SD under roast tool same way with Rapberrypi.etc
(3) then ssh root@192.168.1.28
depend on your IP(LAN),then this is just Ubuntu Server program.must know LINUX.but a little bit. any one can do.
(4)apt-get update
(5)apt-get upgrade
(6)apt-get install mpd
(7)apt-get install samba
(8)apt-get install g++
(9)apt-get install cifs-utiles
(10)apt-get install ncmpcpp
(11)install ympd
(12)apt-get install avahi-daemon
almost these things can do build up Music Server.not difficult to do make good Music Server.then setup mpd.conf and smb.conf after npi-config
each install application some time need reboot.then Switch turn off this mini server because NanoPI does not function reboot correctly.so
manually turn off mini server by power supply switch.
add :added smb.conf [Music] add Music holder on Server.
########################################################
[Music]
comment = Music Folder

read only = no
writable = yes
browseable = yes
guest ok = yes
wide links = yes
create mode = 0777
directory mode = 0777
follow sysmlinks = yes

right now you can get sound from your NanoPi-Neo2 then up grade of MPD 0.19.12 to MPD 0.20.6

Depend on you mind.how about update of mpd. Xenial's mpd is a little bit old now .mpd 0.19.12 is original mpd of Ubuntu Xenial.so going up grade mpd.
from 0.19.12 to 0.20.6 (any version can install if would like to install into your NanoPi-Neo2).first please install as apt-get install mpd then setup
mpd correctly and get sound.then do up date mpd. first make some tempolary directly like tmp . $mkdir tmp in your home directly.home direcrly means
have to add "USER". if your name is "Ben". please add your home directly. as
sudo adduser ben ~ PC asking data of you. finally your PC(Nanopi-neo2 )has home directly of "Ben". /home/ben is your directrly.so login into
your PC have to login as "ben".ssh access is $ssh ben@192.168.x.x or if enable to use Avahi-daemon. $ ssh ben@nanopi-neo2.local can do access
Music Server. then $ su passwd of root "xxxx".
# apt-get install build-essential dpkg-dev autoconf automake libboost-dev libicu-dev
for new mpd install.
# apt-get build-dep mpd
so to do ,,above line can install archive for install new mpd.,source file(archive)to get from
>Music Player Daemon (MPD)from Main Site of MPD then have to compile source file
by "step by step" with command line.please choose mpd source file from above MPD site.first move to /tmp or /usr/src or home directly's tmp.any where.
cd /usr/src
src# wget https://xxxxx.com/mpdxxxxxxxx.tar.gz or tar.xz etc.....any file do you like but same version do you like to install.
src#tar xvzf mpdxxxxxxxx.tar.gz
cd mpdxxxxxxxx
mpdxxxxxxxxx# ./configure
if does not get any problem please to do # make
take time.....then no problem ,, " you get this ""MPD is ready for compilation, type "make" to begin" final of "make"
as root. # make install
will be get new MPD into your NanoPi-Neo2 Server.from 0.19.12 to new version of MPD.then
new mpd is installed at usr/local/bin/mpd
so have to replace path of binary.edit by nano or vi or emacs.
# sudo service mpd stop
nano /etc/init.d/mpd
inside of mpd file ,"watch",,,a part of mpd.. DAEMON=/usr/bin/mpd
replace to DAEMON=/usr/local/bin/mpd then save file then re start mpd daemon.
# sudo service mpd start
#mpd -V
right now you can get now version of MPD into NanoPi-Neo2 Music Server. just do it's.but if does not work I can not insure.
I do not care when does not work correctly.just so sorry but many time I did ,,nothing problem to install new MPD.
if install correct version of mpd please and change path of setup(configure)Ubutu 16.04 with mpd 0.20~ version .
about /etc/init.d/mpd to /lib/systemd/system/mpd.service and mpd.conf setup is /etc/default/mpd so have to read doc where
can got.
Just say Good Luck!! :)

MPD 0.20.6 right now,,,probably sound is a little bit good than before ?????? :)

mpd 0.20.xx Started

Please prepare micro SD of 16 G Byte or more. # apt-get install Please do not mpd. Other libraries you need are # apt-get installed. Since the mpd installed with the
repository is mpd 0.19.12, it is conflicting with the mpd installed at source so the path is incorrect and installation is accurate
It is not possible. The binaries installed by source come from / usr / local / bin. I will introduce the OS first and use old ones. The OS is as follows.
Ubuntu 16.04.4 LTS 4.11.2 Please use this because there is a link somewhere on this site. It is the OS recommended by the manufacturer. AC adapter for large capacity Pi 3 I think that the adapter of
is good. I do not care about I2S DAC, but I think that one using PCM 5102A is good. Please make your own.D.I.Y //translate by Google

Ubuntu 16.04 LTS with MPD 0.20.6 sound is very fine with ES9023 DIY DAC on 1st July 2018

Ubuntu 16.04 LTS MPD 0.20.20　very stable and getiing fine sound so back to mpd 0.20.20

compile again for mpd of 　NanoPi-Neo2 ver mpd 0.20.20 7th July 2018

Compile is not difficult for one. please try to compile mpd archive get from musicpd.org
and" how to" are ,you can find same page
first step is ,to get archive which do you like from "downlod " at left side of view then .ssh access your pi-server # cd /usr/src or any where do you like.
# wget https://www.mpd xxxxxx.tar.gz enter then tar xvzf xxxxxx.tar.gz then you have to compile.
this one of example ./configure --with-systemdsystemunitdir=/lib/systemd/system
end of configure said right now " something like "make".... then you can make then can install mpd into your pi-server.please see instruction of www.musicpd.org.
Note: musicpd.org recently (2018 Aug) seems to have rewritten the install page for beginners. It became easy to read for any one.


for detail: and my mpd.conf is MY MPD just example.
music directly is same as mpd until mpd 0.19.xx and make sure you have to make mkdir #.mpd and mpd.conf have locate at ~/.mpd/mpd.conf and music lib is from
# /mnt/MPD and /mnt/MPD have to link from " /var/lib/mpd/music".mount of NAS and other music server using cifs-utils same as mpd 0.19.xx family.
I can play DSF ,AIFF,any DSD archive as Dop and flac, ogg ,mp3 and any other format.no noise. if did you get noise many case get from communication line .LAN etc.
prefer to use only LAN.if do would like to get good sound without pumping noise from DSD and high sampling music.and if good quality of sound would like to get,please
use analog power supply .do not use AC/DC digital power supply.or Battery is best. and summer time temp is going over 35 dgree C (more than 100 F) inside of room.
if does not have a kind of FAN. probably to get some pumping noise and same noise of scratch noise of Vinil player.please use some kind of FAN. USB FAN is good for cool.
and still you got noise please use good power supply for NanoPi and Raspberry Pi. no use small AC/DC paluse power supply.
Although it is such a cheap music server, you can use the built-in DAC H3 which can use USB DAC and I2S DAC all at once.
Note 1: musicpd.org recently (2018 Aug) seems to have rewritten the install page for beginners. It became easy to read for one.
Note 2: and my smb.conf is MY smb.conf
Note 3: ./configure --prefix=/usr --mandir=/usr/share/man --sysconfdir=/etc --localstatedir=/var --enable-experimental --with-systemdsystemunitdir=/lib/systemd/system --with-systemduserunitdir=/usr/lib/systemd

M.A.L.P MPD Client

M.A.L.P MPD Client for Android --Google APP--

This application is a bit dangerous, if you have any plan, please use with caution. It is also possible to drop the server, sometimes inadvertently erasing the file.
Since it is an android, it can be considered to erase the data of the server after hardening. In my case I deleted the application.



# apt-get install usbmount
Now you can create a USB port under /media/. You can listen to what you recorded on an external PC. First of all we will create a link.
Since usb can be seen with cd /media/, I will link this to the server. This is an example, so the link is different depending on the person.
# ln -s /media/usb /var/lib/mpd/music/Music from the command line. Shared parts can be shared. I explained this above as well.
translate by Google. shown which add USB memory on Nanopi-neo2.

Add USB Memory

This tool does not work fine in this server when using NAS and other server work with together.please remove this application. as #apt-get purge usbmount
be careful to use.when if would like to use usbmount. # apt-get purge usbmount .be carefully to use.sometime does not work fine NAS.

Play DSF by mpd 0.20.90 on 12nd Aug 2018 ,sound is very fine and clear.getting more bass.

Note :mpd 0.20.xx or higher installation is an image of Ubuntu Xienial and installs nothing yet. Please never install with apt-get.
You can install with apt-get mpd 0.19. Since these are different paths, they can not be mixed with 0.20 series.
The above-mentioned MPD of English from this site
Please refer to the installation method. Anyone can use mpd 0.20.xx. mpd 0.20.xx series can play DSF and the setting is simplified.
I think that the sound also gets better. Due to differences in these paths and differences in settings, the 0.19 series archive can not coexist.
I think mpd 0.20.xx is very good and getting good sound from any DAC and it is very stable. :)

Left is FN1242A DAC for RPI and Left is PCM5102A DAC for Rasp I2S but can use as NanoPi-Neo2

Right now using I2S DAC DIY for NanoPi-Neo2 ,sound is very natural and very fine.

Nanopi-Neo2 does not need doing configure kernel. get sound just write alsa at mpd.conf

This circuit(schematic) is just testing for NanoPi-Neo2 24bit 198Khz DAC but discontinue Model IC

Install of NetData "can watch Data Server around conditon from so fa way"

By installing NetaData you can see the status of the NanoP - Neo 2 mpd music server remotely. There are introductions on other sites such as this, let's install first.
I think that installation is possible relatively easily because I use git.
----------------------------------------------- -----------------------------
$ sudo apt-get install zlib1g-dev uuid-dev libmnl-dev gcc make git autoconf autogen automake pkg-config
$ git clone https://github.com/firehol/netdata.git --depth = 1
if did you get error, just $ git clone https://github.com/firehol/netdata.git
$ cd netdata /
$ sudo ./netdata-installer.sh
------------------------------------------------------------------------------
then you can see http://your music server IP:19999 from your local PC
for ex: http://192.168.1.28:19999

I can understand the state of the CPU, but this does not mean I know the state of the sound, but if it is remote, it may be useful for management etc.

Installing last fm

First of all, please register last fm.
Next, access it with ssh and install the next application.
$ sudo apt-get update
$ sudo apt-get install mpdscribble

Then edit /etc/mpdscrobble.conf and /etc/default/mpdscrobble
Edit mpdscrobble.conf file
[last.fm]
url = http://post.audioscrobbler.com/
username = lagartXXXXX
password = xxxxxxxxxxx
# The file where mpdscribble should store its Last.fm journal in case
# you do not have a connection to the Last.fm server.
journal = /var/cache/mpdscribble/lastfm.journal Please edit and save as above. For music servers that do not have WEBUI, register and edit them all in the same way.
/etc/default/mpdscribble file editing
# Whether to enable system wide daemon
MPD_SYSTEMWIDE = 0 "0" to "1" please.
# Whether to enable system wide daemon

I will do as above. Then start with $ sudo /etc/init.d/mpdscribble start. after reboot.automatically started mpdscribble.
If you are worrying about it, you can check it with $ /etc/init.d/mpdscribble status. This will upload the list to last fm,
It may be a dangerous application depending on viewpoint, but it is very useful application. If it is not on the list, it is recommended that you listen to such a song.
just like show next on Last fm site.

MPD is down .so no sound again from mpd 0.20.09

re-install again mpd 0.20.9 , one thing mpd is going change other system.new mpd version is mpd 0.21.3 and they change how to install mpd.no configure Linux known.
so does not have ./configure and make .acutally I do not understand how to install mpd 0.21.3. some day I will tell you here.
so mpd 0.20.9 install again Nanopi-Neo2.just get Ubuntu Xenial into microsd.just same way used be.
setup file located at /etc/mpd.conf I am using as root.get mpd-source and compile then make and make install.same as before.then
#systemctl start mpd for start mpd after install mpd by hand.
then check status of mpd show next.

show mpd start after install mpd from source.if does not get active means show as inactive means not function mpd . so edit /lib/systemd/system/mpd.service
[Service]
Type=notify
ExecStart=/usr/local/bin/mpd --no-daemon most case does not find mpd.conf file so have to add place of mpd.conf show next.
ExecStart=/usr/local/bin/mpd --no-daemon /etc/mpd.conf
then re start mpd or reboot system NanoPi-neo2 music server.if fine work mpd. add next comand for auto start mpd when reboot system.
# systemctl enable mpd from auto start next reboot.
any time you can check condition of mpd.by
# systemctl status mpd

I installed various applications from source, but finally I do not read DSF. After all it became reinstallation of mpd. Stop the root's home directory and save the configuration file as /etc/mpd.conf
That's it. A new mpd 0.21.3 was issued. Instead of compiling with Linux knowledge, this is a method of installing Git or a third party like mpd. Make and install method is 0.20.9
It seems to be until
. I have tried several times, but I do not understand at all, I will wait for someone to install with a pillar. 0.21.3 has many wonderful things written. It is the next generation MPD.

How to use Nanopi-Neo 2 in my case

Because NanoPi - Neo 2 does not have image output(HDMI), it is a one - board PC that is very hard to use stand - alone. It is very convenient to prepare another one. Another one is to install Volumio 2 and use that music server as NAS.
There is no need to be another Nanopi-neo 2, RaspberryPi Zero can be used, even an old personal computer that does not need to be used It is used as a server for step-up in order to be stable. Sound does not go out there
I will put a good quality sound from Nanopi-Neo 2. NAS for NanoPi-Neo 2 which has been sold cheaply recently also does not matter. In a sense I think that it is good to install Volumio 2 on NAS for Nanopi - Neo 2.
in this case using Nanopi-neo2 with Volumio2 and this micro Music server using with other Music Server like moodeaudio and runeaudio music server.In my case Volumio 1.55 is installed in raspberrypi B + as mentioned earlier.
There is 2 Tera USB connected, so I am sharing the archives there.and inside of HDD is separated each category of Music and Artist.off course I can play music saved on my wife's PC 's share.
even google strage music too.
this MPD Music server does not have WEBUI so must be use SKY MPC and Cantata. I am using mpd 0.20.9 and using DIY ES9023 I2S DAC getting good sound.

What should I do? Installing new mpd

Meason builder seems necessary. It seems that these are usually executed by GUI, and how do you install it on a PC without HDMI like this server? The project has been on for quite some time
It seems there was a problem, but. First you need to click on the link below to study.Why did that happen? That's because the MPD currently present depends on Debian, as the Debian package moves to Meason Builder.
mpd is built with Debian's package. The archive depends on Debian Linux, saying the source, which is the cause.

The Meson Build system

Install Subsonic on NanoPi-Neo2

Install Subsonic on Nanopi-Neo2

Actually if one's would like to install into Ubuntu this Music server need install Jave .but terminal said
add-apt-repository does not have...so getting error. then have to install repositry for java before "software-properties-common"
$ sudo apt-get install software-properties-common python-software-properties
$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
$ sudo apt-get install oracle-java8-installer
you have repositoy in your Ubuntu so can install java.
any way , Madsonic and Subsonic need Java, both are using Java.which is best I do not know depend on you like.one thing can not use with mpd.
This will install Oracle - Java 8. The problem is to change from Subsonic to Madsonic. Unsubscribe Subsonic unnecessary.
I think that it is better to use purge, but since you can not delete the directory you created yourself, you can delete it entirely by setting $ rm -R / directory. Both subsonic and Madsonic are relatives.
The installation method is exactly the same with exactly the same structure. I do not think you can use either, but you can not put in two, MPD can not mix. When sound is output with MPD, the load is heavy and the sound is interrupted. It is positionally close to MDDA
It is existence. Just to be sure, if you compile the source you can UN-install. For Ubuntu uninstallation, use # apt-get purge xxxxx 1 or # apt-get remove. In the case of Madsonic
Please use
Ver6. Archive in 2016 and two years ago, I think that it is the most stable. If you have a host PC, please download the file to Windows, Mac, Linux.
After that, will create a shared folder on Ubuntu side of Naonopi-neo 2. Drag it to the shared holder using samba. will install from that holder. That is, wget is affected by protect etc.
Since I can not download the archive, that is where saved this is Google's archive server, so can not use WGET here, so let's install it like this. I hope wget can be done
This is because downloading of files from this like google server can not be done.doing #apt-get then stop install terminal said $sudo apt-get -f error ,,,,,please try (run) $ sudo apt-get -f
then re-install resoisitory java. after $ sudo apt-get update.

How to use Streamripper

streamripper http://62.210.75.134:8000/stream/5/ - u 093800 -r -R2 http://62.210.75.134:8000/stream/5/ Write from the command line like this.
There are cases where the $ streamripper URL is good and not so. If you can not get in there, please put in the middle and the scoop.
$ streamripper URL -u 093800 -r -R 2 URL starts ripping, but if you are in the middle of a song, skipping will be entered. Ripping starts from the beginning of the next song.
For Debian series you can install with # apt-get install streamripper. For Fedora Core you can install with # dnf install streamripper.
You can record songs on any Internet station. In the case of Nanopi-neo 2, it is good to create a recording directory of the shared directory and enter it in command within it.
I think that SKYMPC is good for IP acquisition, but any Internet radio application can do it. In my case I am using Nightingale installed on Linux.

It is a very excellent application.

When ripping CD started using Linux, I used Asunder recently with grip

CD :Krystian Zimerman's CD

Sometimes I can not rip it. I can do ripping this time, but it stops on wav many times on wav. I managed to rip it somehow by changing the extension. It is not NAS or rip the body PC
If you copy to other Music Server, you will get an error. Only 2 songs in 6 songs were copied and the other songs were not completely copied. I tried ripping with ripping taken to the NAS side
While ripping is possible, although playback on the NAS side is possible, playback on the other Music Server side can not be done, the CD player has failed a few years ago and he is not using the CD player and then the PC The attached Rector
So, I listen to ripped sound source as Flac. Although it is Zimerman's piano that I purchased, why can not I listen, why? And wav extension has disappeared except in the holder. So I will add extensions.
I think the filer is good. Add the WAV extension to the songs existing in the shared part. Then use local VLC to play and see. If you can play it I think that you can play through NAS.
Put the 6 songs in 1 to 6 folders and transfer the file. I converted it to DSF but it was able to save it well. When you copy it the extension will be deleted. So I could not recognize it as music.

I2S DAC DIY

I2S DIY DAC ES9023 Sabre for NanoPi-Neo2

Schematic Diagram ,very simple and get good sound

This CD UCCD - 51088 is a CD of Claudio Arrau 's piano. It is a label of DECCA.
Recording is on 1970 in Berlin. I think that the way to play the piano is alive with his recording at the young age.
I did not know that Liszt's songs are so romantic. I have several Liszt CDs, but I listened to this song and recognized it again.
It's a very good recording. I think that I bought a good CD. Please ripping with Asunder by Linux to wav. flac will generate an error.
often get error of Name of album so please use to try Rythmbox for ripping.you can get good results.
Track names and album names may not appear in Asunder. It does not appear unless a list is registered in CDDB, but in Linux case Amarok has an example to read, so if you do ripping with Amarok
It might be good. This may also be read or not read. If you do not read album names with Grip or Asunder, try using Rhthmbox.

Just update from WebUI volumio2 for NanoPi-Neo2 2019

MINIDSP is displayed, it is no longer Volumio 2. In other words, this OS is thought to be developed by MINIDSP. Searching for MINIDSP will hit orphaned manufacturers. Manufacturer called MINIDSP company
Displayed. This company sells applied products of one board PC. You can find out by searching. There is also a branch office in Japan. However, it seems to be only this site.
Like this corporate pick-up company, the operating system is charged. That is, it is suggested that it will not provide Nanopi-Neo 2 OS. Volumio is supposed to be responsible. To say that you are charged development slows down
It is suggested that there is a possibility of extinction as it is. Volumio 2 Volumio 2 of Nanopi - Neo 2 has become MINIDSP. If a problem occurs, please reset it to Factory reset.
Nanopi - Neo 2 It is hard not to update on volumio 2. With the version of MINIDSP, reading of files does not go smoothly. Since various troubles will occur, be careful.
Please note that updating Nanopi - Neo 2 Volumio 2 will force it to MINIDSP.

MPD is root @ NanoPi-NEO2: ~ # mpd-V
Music Player Daemon 0.20.9
So I am using MPD 0.20.9 final version of mpd.of version 0.20.XXX family.
The controls are SKY MPC and Cantata. The album information is displayed in Cantata, so I use these two MPD Clients.
The Internet can be selected by Cantata, and SKY MPC is indispensable for the selection of fine music. Enjoy high-quality music with the NanoPi-Neo2 and the ES 9023 DIY DAC. There is no need anymore
You can enjoy music by listening to music very much by using a combination of NAS and other Music Server in the home LAN.
There are almost no extensions that can not be played back. You can play DSF beautifully as DoP.

About SPDIF of Nanopi-Neo2

How good is TKZ for putting out a good archive, but the output other than I2S is somehow an open collector? I realized that to say. To something site
It was written. Although there is a pull-up resistor on the RX pin of pin GPIO11 next to SPDIF by remote control, it does not come out in any state because it is not attached in this nano pie
If you attach a pull-up from + 3V of 3K ohm to this pin, that is, the pin next to the pin of SPDIF, a dirty waveform appears, so let's apply this pull-up resistor.
I think I will add a waveform shaping circuit to this output with an inverter. You will now be satisfied with the output of SPDIF. Of course, let's use Volumio2 which can do SPDIF of TKZ. The following is
Circuit and waveform. To be precise, it is far from the SPDIF waveform, but I think that I will try.I made a sound when I connected it directly,
but I think that it is correct to shape and connect the waveform as well because the level drops.SPDIF was made with NanoPi-Neo2. :)
The pull up resistor is a 10K resistor(painted ■ ) connected from the + 5V of the SPDIF output. One resistor is enough. Has added a buffer just in case. I use an inverter, but can be use NAND,

SPDIF Test by Nanopi-neo2

then ,, out put is a little bit not enpugh level so can not drive to SPDIF DAC, so added TTL buffer by SN7404 inverter . same as above schematic. wave form show next and
small TTL unit.and got good result.TTL out is around 4v pp.wave form is quite good.

 

SPDIF out added TTL Buffer

My Mistake Pull Up Resistance

I thought something was wrong. First of all, the sound is strange. The position of the pull up resistance. I didn't write anything on the schematic, so I could get some hints from the temperature sensor's schematic. It is a position of pull up resistance.
As it is an open collector, it seems correct to put a pull-up resistor on the output. The need for the invar circuit has been eliminated. So let's bring it directly. The pull-up resistor can be connected by connecting resistor 10K to + B3.V as shown in the circuit diagram.
There is a very beautiful hide pattern like below. By the way, if the load is connected, the Peak to Peak will still fall, so it is safer to leave this inverter attached. You can play DSF DoP without any problems.
If you don't mind, you don't need a buffer circuit, but the load is heavy and Naopi-Neo2 may be broken. The buffer circuit just changed the position of the pull-up resistor as it was.
With Volumio 2 SPDIF,
Above all, I think it's great that you can use your own DAC close to you. Thank you very much, Mr. TKZ. As Volumio 2 has no freedom, I think MusicServer only with MPD is good. In my case, DAC uses FN1242A
So the sound is very similar to the ES9023. This is a feature of the 24bit DAC, it feels very good. I'm listening to Satie now, but it sounds good and it sounds great.

It is a very beautiful waveform. Waveform from SPDIF of NanoPi-Neo2

when does not use ssh by volumio2

Note: If you have more than one Volumio on your home LAN running, you can not access it if you try to access a new Volumio 2 with ssh, or you can not pass the password.
if can you see by Browser like firefox etc. first enable ssh where is volumio.local/dev
click ssh one time.then you can access by ssh.

ssh root @192.168.1.12 -l volumio

I think you can now connect. IP is each person different IP depend on condition of Modem.

My DAC made on 1st Dec 2009 connected with Nanopi-Neo2 from SPDIF

Demonstration SPDIF By Nanopi-Neo2

As a result, I added an inverter. Even if the output from Nanopi-Neo2 GPIO is connected, the waveform will be disturbed, but playback is possible. I think it is better to put a buffer. Add an additional circuit in the Rapberry Pi experience
Because there was an experience that power was not turned on when there was a risk of high temperature due to the burden on the main body, if it was possible with only one resistance, I added a buffer with one IC. The waveform is beautiful. The image is attached below.
I have uploaded the operation status to YouTube.

NanoPi-neo2 SPDIF out and using DIY DAC

People who use
Nanopi-Neo2 may also use Music Server. In other words, since there is a shared part, various drivers can be experimented by rewriting /boot/sun50i-h5-nanopi-neo2.dtb.
Copy all Volumio2's / boot / database from above to INTERNAL. Copy these *. Dtbs to the workstation. It is good to rewrite this *. Dtb when necessary. Copy to the shared part of that OS
Rewrite /boot/sun50i-h5-nanopi-neo2.dtb. You can copy it with the cp command. This *. Dtb is important, so save it in some important folder. Thank you, Mr. TKZ.

Although the TOS link was invented by Toshiba, the meaning of TOS is also a meaning of throwing. Transmission method of optical fiber has jitter etc.
Also, the transmission speed is not fast, and metal cables are generally considered to be faster. The TOS link also differs depending on the device, but at best it will be up to 98Khz.
We recommend using metal cables.

Volumio2 for Pine64 64bit Single Board PC and low cost

How to make Pine 64 sound with little information

When I searched internet, it was described that SPDIF works from Volumio 2, but it was unclear how to connect. ... Well, I think you all know that there is an Euler port.
I made a drawing, so please try it by referring to it. I think it is finished with one resistor and one capacitor. Please experiment to see the value of the capacitor. A beautiful hide pattern is output.
The output of SPDIF is available, so it can be connected to an external DAC. I was able to put out the sound normally. I have uploaded to youtube. More if you can use MoodeAudio or RuneAudio
It's useful, but it has increased usage considerably because only USB DAC can be used. Other I2S seems to have come out. The waveform is very beautiful.
Raspberry pi 3 feels faster than before. The sound has also changed.
It is actual feeling to say
. I think that the waveform of the SPDIF is also very beautiful and influences the sound. I also feel that there is less jitter. For a long time, the sound was not satisfactory except for the USB DAC, but I saw the waveform by looking at this Euler port.
The I2S waveform is also beautiful, and it seems that the master clock is also out. Although it is necessary to analyze, it became a very favorite board. If you have a good DAC, you should try it.
It is good point that power consumption is low. However, this is only possible on Volumi 2 OS. Listen to the sound all day long, the sound is good, the sound is clear. RaspberryPi 3 does not have SPDIF, so if you do not connect HAT
These operations can not be done, but in case of Pine 64 SPDIF comes out from the body as it is, so it is very convenient. I think the jitter is also less.
If you replace the latest version of Volumio2's mpd binary, mpd will be the latest. Copy and use the latest version of rapberrypi 3 mpd. Copy to Pine64's volumio2 /usr/bin. under ssh .
then Music Player Daemon 0.20.18 (d3559e8-dirty) to Music Player Daemon 0.20.6 then easy to replay DSF as DoP.
PINE 64 It can be connected to any DAC with a little processing like one sheet.
There are DACs without USB, some with an SPDIF input, and some older receivers have a DAC input attached. They come alive.
You can enjoy music with Music Server and external DAC. Of course you can also receive internet radio. However, a LAN is required, and a line to which the LAN is connected to the Internet is required.


Pine 64: About Music Server
1) I2S signal is emitted.
2) get a Master Clock.
3) get SPDIF.
4) Dedicated OS is Volumio 2

This allows you to get sound with any I2S DAC or SPDIF. It also has a built-in DAC.all of get from Eluer Port.

I am not sure if it is used properly, but I think it is correct usage that SPDIF will produce a beautiful wave.

You can get the signal from SPDIF. We recommend that you try to validate on your own. I2S is also out, so I think it can be used normally.

Pine 64 uses I2S I2C DAC, and SPDIF uses Euler port. This solves everything.

After compiling for a long time, the temperature of the main body exceeds 120 degrees, and finally I can not start. You have to bring time-consuming source to compile.
It is the fate of a small one-board PC. Nanopi-Neo2 was dead.

For now, it was mpd 0.21.6 for Nanopi-Neo2. Installation of this wonder is 0.21.8, but the display is 0.21.6.

Sorry, I feel like I'm getting a sound, but I can't get a sound, and I think it's possible to install it in the Xenial version as well.
After compiling for a long time, the temperature of the main body exceeds 120 degrees, and finally I can not start. You have to bring time-consuming source to compile.
please turn off leave alone 1 day then turn on probably start again. However, compilation of mpd 021.8 in Ubuntu Xenial is at high risk, as it is likely to break micro SD during compilation.
DietPi can be upgraded, but upgrading with Ubuntu Xenial can break the OS. I made three micro SD cards unrecoverable.

Application for NanoPi friendlyarm is a lazy maker. The support system is not good. This is true for all the products made by Chinese. Even Chinese-made, English-speaking country's support is required.
In short, Chinese products are at risk. I think it would be nice if there was a support group in English-speaking countries other than China. There is a company called MINIDSP, which makes applications and products for a fee.
I think that I can not discharge the application free of charge because of this kind of relationship. It's always a dirty Chinese way. Still, Pine 64 would be better. The NanoPi-Neo2 is small and attractive, but has a limited operating system, but there is no point,
MiniDSP is an introduction to AboutUS with a picture of an Anglo-Saxon, but this is a fake and just a homepage for a show.they should be use a dirty Chinese face photo.

NanoPi-neo2 becomes ICECast Server

Use NanoPi-Neo2 as something else. A file server is available. A music server is also possible.
Since the OS is limited, it was the ICECAST server that wanted to look for something. Reference image
Attached. Please go to see the reference link yourself. My site restricts access from IP in Japan. Sorry if you can't see it.

Would you like to install with Ubuntu Xenial? Anything is fine, this is the startup screen

IceCast Start by Nanopi-Neo2 on 11st Aug 2019

Mopidy installation

Initial screen with Mopidy installed on Ubuntu Xenial

First, let's install pip.
Save get-pip.py with wget.
#python get-pip.py: Hit the left command in the same directory.
# apt-get install curl
#curl -kL https://bootstrap.pypa.io/get-pip.py|python
Please make sure you have root privileges. Enter ssh as root. Change the root passwd.
#pip -V
You can install with pip. You can install mopidy on any version of Ubuntu. Refer to the links below
Please install it yourself. This makes Mopidy possible with Nanopi-Neo2. From now on, I will report along with the experiment. Sure first
# apt-get update
# apt-get update
Please do
#sudo wget -q -O /etc/apt/sources.list.d/mopidy.list https://apt.mopidy.com/xenial.list
The last .list is stretch.list on the introduction site. Please change it to xenial.list.
Please install referring to Installing and using mopidy .

Display of Cantata on Fedora Core 26 Linux

Cantata on FC22 Linux or later does not display the cover as expected, so I installed an old version, but the result is the same
It seems to be related to libraries and QT on workstations. It seems that the best result is obtained by compiling with git by supplementing the library.
Here, I tried git installation. First, install git on the OS. Once you get the source URL with git
$ git clone in a suitable holder https://github.com/CDrummond/cantata.git
Run this way. This will create a cantata directory, then $ mkdir build after $ cd cantata and then $ cd build
Compile in this. How to compile is described in INSTALL, please read carefully and compile. Because we use QT5
QT5 needs to be installed.
If you use Raspbian, you don't need to compile, you can get a nice display with a nice display.

mpd 0.20.9 MPD Server built up

By Cantata 2.4.0 version git mpd 0.20.9

Install Dietpi Music Server mpd 0.21.5

Basically, it is the installation of MPD server. Sound is relatively easy if you have a USB DAC. Raspbian Buster's mpd was 0.21.5, so DietPi Buster's mpd is 0.21.5.
Dietpi seems to be built on Armbian, and sound can be produced with a solid operation. First, let's install the basic application. How to install is the same as Ubuntu Xenial.
mpd does not need to be compiled, you can install binaries and install the latest mpd. DSF can be played easily with DoP. If USB DDC is inserted in USB, it is automatically recognized at the time of installation
makes it easier to install applications. There are many media server applications available, so it's a good idea to select and install them.
The sound setting uses Dietpi-config and Alasamixer. alsamixer cannot be installed, but the configuration image appears in Dietpi-config, so you can use it to configure the driver.
In my case I used Dallas's DDC, but I chose it because it appears in the driver list. Make detailed settings in /etc/mpd.conf. Same as the item set in xenial, but m
I wrote and set it referring to /etc/mpd.conf of moodeaudio. moodeaudio's mpd is 0.21.xx or more, so I think it should be written in the same way. The setting is different for mpd less than 0.20.18
Please be careful. DSF DoP playback can be played without any problem. We provided a small server for Raspberry Pi and Nanopi-Neo2, but say that Nanopi-Neo2 sounds better.

#systemctl restart mpd.service
#systemctl status mpd.service

If you get an error, edit it little by little, Use Dietpi-config and Alasamixer for sound settings

Dietpi Step by Step

Todaye started compile mpd 0.21.9 by hand on Nanopi-Neo2 Music Server with Dietpi on 27th Feb 2020

compiling mpd

mpd is now 0.21.9. An error occurred in this state, so I copied mpd.conf locally and it was OK.

The details are OK after copying to root/.config/mpd/mpd.conf and restarting the MPD.

Play DSF as DoP

mpd 0.21.9 on 1st Mar 2020 I compiled and installed the source with Mason and ninja, but it is unknown from this version, but only one Client is allowed
You cannot open two on the same LAN, this is important. It is not possible to launch a client with Cantata. Apparently, there is only one Client for versions over 0.21.xx
However, since it can be done with MoodeAudio, the operation is up to 0.21.16. After that, there is only one Client. The reason was to reduce the load.
The display on Cantata can be done in detail. The same goes for sonata.Then I installed it again this year. dietpi Buster. it has more than one Client.
Even if I run two or more Client, it does not freeze, I can use this.
I don't know whether it became because I was careful at the time of installation, or because I added max_connections "128".

mpd client can use 2 more of them. nothing promlem to use 2 more mpd clients

Volumio2 Nikkov Version 2020 Oct 29er

Volumio2 play Jazz

Dietpi SPDIF sound is low

Extracting DTS from TKZ's Volumio2

First, extract the SPDIF driver for TKZ's Volumio2, just the SPDIF of the DTS extension. Copy it into Dietpi's /boot/dtb/allwinner/. This Dietpi uses Buster, so mpd 0.21.5. Volumio for Nikkov and TKZ version of MPD cannot compile MPD, it's not possible to compile MPD from old Ubuntu.
I'm using it, so I can't compile the library and install a new MPD. The sound is satisfactory enough.
The Nikkov version of Volumio2 has mpd version 0.20.12. Edit the ArmbianEnv.txt and it will recognize the driver. It's not automatic, you need to rewrite the file.
You can set it up by ssh, but when you write to the microSD, you need to add an empty ssh file and edit this file outside Nanopi-Neo2.
The MPD is also 0.21.5 and the playback of DSF will not be a problem.

Now we will compile and install mpd. As usual, you will have to download the mpd source and compile it. The method of compiling and installing has been changed.
This is a change in the method of installing mpd from source since 0.21.XX. In the case of Dietpi, there is only root, so please add a general user. In this state, use
In this state, use #. sudo is not recognized. Please install git,g++, C++, C++17 ,C++11,C++20 cmake,ffmpeg,curl,avahi-daemon,sox etc. before you do the following.

The best way to listen to Internet broadcasts is using the mpd Client with mpd.

The best way to listen to Internet broadcasts is to use the mpd Client with mpd. mpd Music server does not use the WEBUI, so you need to create a holder on the server to store the list of stations.
You can save the station data of PLS extension in the holder and select the station from there. The data is shown below. The data is shown below, unzip it in a specific holder and use it.

Since it is different each time, read and understand the DOC in the source and install it. I think you can update it every time.

There is nothing special in the circuit diagram, only one capacitor and a good non-polarity capacitor Muse is good and only a pull-up resistor. Cut the universal board into small pieces and header Attach
and you're done. The hardware is only Nanopi-Neo2 and RCA connectors. I attached an IC for the buffer, but the sound gets worse, so one capacitor is enough.
I don't think this capacitor is necessary either, but it's not good if there is a transformer on the DAC side, so I put in a capacitor for the time being.
After that, please make a good DAC. I think you can buy it. Since the master signal is output, I think you can move it with I2S.

That's all

Music Server Comparison

Comparison of Rune Audio mpd 0.22.6 and Diepi 0.22.6. The sound is exactly the same and the finish sounds the same. Dietpi Nanopi-Neo2 sounds the same as Rune Audio. Both use external DAC with SPDIF
Dietpi Buster mpd 0.22.6 whose sound has improved just by updating the MPD.

Create m3u Create playlist

$ ls * .mp3 | sort> playlist.m3u

That's it. If you open the terminal and enter the above in the holder, m3u will be created automatically. Because I have Linux
This is easy to make. playlist name make proper name of file

The internal file is m4a, but please change only the extension

Playlist makes

Dietpi mpd 0.22.6. I feel that the sound is better than Volumio2 and Moodeaudio 7.2. Volumio3 has mpd version 0.20.X. That's because I'm using Ubuntu Jessy.
You can't cross the 0.21.x wall unless you make it Buster. Moode Audio also has mpd of 0.22.X, but DSF cannot be played. Here, DSF can be played by Runeaudio and Dietpi.
Dietpi also uses Buster, so it is up to 0.21.5, but you can compile the source and install mpd of 0.22.6 or higher. It is very stable. Rune Audio on Raspberry pi 4 is from samba
There is a method that cannot read the music of other servers because it cannot be installed. Mount with Cif-utils without using Samba. Nanopi-Neo2 music server can be used with mpd Client
I need it, but it plays music very comfortably. I use it every day and it is very stable. The sound depends on the DAC, but I think it's a great music server. The price is also the lowest. It ’s small and it does n’t get in the way.
No I think you can use it with a DAC, or you can use it by outputting a signal with SPDIF.

Cantata and mpd

show you ssh from Fedora Core linux x64 Introducing the screen accessed by ssh and Cantata. mpd is the latest version of mpd 0.22.6 that was compiled and installed.
To use mpd freely, be sure to install Cantata on your main PC. With Cantata, you can freely control Dietpi mpd Music Server. mpd 0.22.6 is
Great application. With Nanopi-Neo2 and Cantata with mpd installed, you can listen to music broadcasts from around the world, and of course, play music stored on your workstation.
It is possible. You can play music from the hard disk connected to the LAN and music from the NAS. You can also control Runeaudio, Volumio2, etc. with Cantata.
The workstation uses Fedora Core Linux. Cantata also installed the file that compiled the source.

Downloaded from Cantata 2.4.0 Github with the source compiled and installed

Music file share update (Cantata)

First, transfer music files from another PC to a server with a hard disk through Samba Share. After that, click Refresh Data base of Cantata
Update the file. It takes time depending on the size of the file. You can see that an icon like a gear appears on the right end. If it is spinning, it is being updated. If it stops, the update is complete.
Please open the nearest folder and update. If the music server can be updated, it can be read from the mpd client. If only reading is complete and there is no sound
The directory containing the music files is not mounted, so please update the connection or mount it from the ssh command line using Cif-Utils. I think there will be a sound.
There is a sign of update in the blue mark. Click the shaded icon at the top of this to bring up the settings menu.

using cantata and control Nanopi-neo2 Music Server

NetData Install

$ sudo apt-get install netdata
can install Nanopi-Neo2 and Raspbian Buster too.

dietpi-cloudshell command

This is a new command I found. Please see the link as it will be introduced. There is a setting to read NAS in this, so please try it.
In my case, the one with the hard disk is MoodAudio Rapberry pi4.
Two hard disks are 2 Tera. In my case, this is mounted with cif-utils. The following is the command.
$ sudo mount.cifs //192.168.1.3/81EC-DFF5/ var/lib/mpd/music/Music2 -o noauto vers = 2.0 iocharset = utf8
$ sudo mount.cifs //192.168.1.3/A4C0-F0F0/ var/lib/mpd/music/Music -o noauto vers = 2.0 iocharset = utf8
The above operation is no longer necessary. Please try. Actually, I think that only the above operation is the best result. Please implement cloudshell at your own risk.
I'm not sure if this works, but there is an item to mount in this cloudshell. In other words, I think it will be an automatic mount.
This cloudshell command has one mount. cif-utils The df -k obtained by manual mounting is as follows.

Last Fm Review

First, register on last fm.
Next, access with ssh and install the following application.
$ sudo apt-get update
$ sudo apt-get install mpdscribble

After that, edit /etc/mpdscrobble.conf and /etc/default/mpdscrobble.
Editing the mpdscrobble.conf file
[last.fm]
url = http://post.audioscrobbler.com/
username = lagartXXXXX
password = xxxxxxxxxxx
# The file where mpdscribble should store its Last.fm journal in case
# you do not have a connection to the Last.fm server.
journal = /var/cache/mpdscribble/lastfm.journal
Please edit and save as above. For Music servers that do not have a WEB UI, register and edit in the same way.
Editing the file in /etc/default/mpdscribble
# Whether to enable system wide daemon
Please change "0" to "1" in MPD_SYSTEMWIDE = 0 .
# Whether to enable system wide daemon
MPD_SYSTEMWIDE = 1
Do as above. After that, start it with $ sudo /etc/init.d/mpdscribble start. Binaries are under bin, so reboot
It will start, but if you are uncertain, you can check it with $ /etc/init.d/mpdscribble status. This will upload the audition list to last fm.
It may be a dangerous application depending on how you look at it, but it is a very useful application. If it's not on the list, I'd recommend listening to a song like this.

Netdata installation Dietpi

Dietpi NetData is already included in Buster, so installation is easy

sudo apt update
sudo apt install netdata


sudo emacs /etc/netdata/netdata.conf


[global]
run as user = netdata
web files owner = root
web files group = root
bind socket to IP = 192.168.1.X //// your music server IP at home

This will save it. I only use emacs, so please install emacs.
$ sudo systemctl restart netdata
$ systemctl status netdata

In case of Dietpi, please do not install the application with Dietpi-software. In this case,
it is different from the general Ubuntu path, so it can not be set smoothly.
Please install according to Buster. You can install NETDATA.

2021.5.24 on the morning happen strange things

At midnight, my MPD got caught before I fell asleep and went to bed. If you remove two hard disks, some people have formatted them because they have been invaded from the outside. Moode Audio is dangerous.
This is the fourth time. About 50,000 songs have gone somewhere. It seems that some of them have been copied. Sometimes the music is playing from the lower floors as if I heard it somewhere.
In this condominium, the owner of a former PC cram school called MR Ichikawa lives downstairs and sometimes breaks into my server. Last night I forgot to remove the HDD before going to bed.
Did you format it? It was pure white. Did you format it rather than delete it? This is his fourth time. The same thing happens in the previous apartment
There were several times. There is no sound. When I looked at the mpd source on the site, it was mpd 0.22.8. Maybe there was an update this morning?
He immediately downloaded mpd 0.22.8 tar.xz. I wget using ssh in Nanopi-neo2. It took about 5 hours to compile.
You can use the library that was originally installed, so I think it will take about 6 hours to install in rare. The sound has improved. I realize it.

play by new mpd 0.22.6 on 24th May 2021

The source is being compiled
mpd.conf this time

mpd is now 0.22.8

mpd update Dietpi

If you are using Dietpi Buster, be sure to make a sound. samba, cifis-util, C ++, ffmpeg, Gcc, cmake, boost_1_67_0 or the latest
I think that the boost that is already installed is old, so please download the latest boost and unzip and install it.
doc mpd After confirmation
Install the library as described on the mpd site. If you get an error during compilation, follow the error and do what you need to do.
This includes installing libraries and creating directories. Please delete the mpd installed by apt-get.
Start by downloading the source of the latest mpd file. Make a suitable holder and download the source in it.
After that, the installation will start according to the description of mpd. The OS on which mpd can be installed is Ubuntu Buster, Dietpi Buster, and Armbian Buster.
In the case of Nanopi-Neo2, it will take about 7 hours to install mpd. This is the total time including the library. This time to 5.22nd 2021
Applies to the updated mpd 0.22.8. Anyone can install it if you install it step by step. All of this is done by accessing with ssh.
I think it is very convenient to have samba installed for testing. Relatively easy from the impressed Dietpi Buster music server
I think you can easily update mpd.
systemctl restart mpd
systemctl status mpd
if do you have error please fix part which has error.then restart mpd again to try.

Trouble occurred

1) The sound is quiet,
2) Volume control is not possible,
3) The sound is hard
That's the point.
/boot/armbianEnv.txt
you look at spdif has been removed. Sun50i-h5-nanopi-neo2-spdif.dtb in /boot/dtb/allwinner was deleted.
Maybe Dietpi did something wrong and deleted this file. Expecting dietpi-software will be a big deal. The directory will also be deleted.
This was a big problem. If there is a problem with the music server, we recommend removing the hard disk. There is a possibility that music and songs will be deleted when the OS deletes the directory without permission.
Therefore, it is necessary to install the TKZ driver introduced earlier again. Please re-edit armbianEnv.txt as well.

status mpd has started cleanly

Volume could not be adjusted because there is no mixer type "software"

very stable mpd 0.22.8 and getting good sound but this one need good DIY DAC

Just same way of raspberrypi .this case is Nanpopi-neo2 and using Dietpi.almost same way to get update mpd

mpd 0.22.8 by Nanpopi-neo2 sound is very good on 3rd June 2021

About 100 songs were ripped with flac, the album art is beautiful

While connected to your home LAN, search for an image with another browser, look at the label, and cut it with shutter.
The save destination is a hard disk on the LAN. Save it as Folder.jpg.
After ripping, save it in a folder. You can copy it. The resulting image is the image shown above.

Testing sound by DIY DAC FN1242A 198Khz 24 bit

It's not relatively difficult to post a video, but it was quite useful because there was Adobe flash before,
but I shot it with mp4 made by Smartphone and the video is as it is I don't ride.
Therefore, edit it so that it can be seen on the net. It will take a few minutes. I use an application called AVideomux on Linux. You can now see it online.
Why don't you put it on Youtube?
It is copyrighted and cannot be posted on youtube, and even if it is uploaded, it will be muted,
so it is posted on the site like this. This is also a violation of copyright law.

Suddenly I have no sound, I've been on IPV6 since yesterday, and a guy downstairs called Ichikawa is misbehaving through my LAN. It's an imperfect connection to the apartment.
Warning: The unit file, source configuration file or drop-ins of systemd-journald.service changed on disk.
Then I looked at the site and it says to do # systemctl daemon-reload, so I did that and the sound came back.

mpd update doing now from mpd 0.22.8 to mpd 0.22.9 on 1st July 2021

for install .took about 3 hours and a half then mpd 0.22.9 on 1st July 2021 by Dietpi

This is the state of Netdata. I wish I had shown this during compile

Installing mpd

First, download, unzip and compile the following: mpd 0.21.x. The compilation method has changed since then. This is due to the origin of Debian Linux.
Download the necessary mpd sources from the mpd site. Do something like: $ sudo wget ftp://xxxxxxxxx.org mpd-version.tar.xz. This will download the source.
This source can be downloaded by creating a folder and using # wget within it. Before doing so, you need to install the following libraries.
tar xf mpd-version.tar.xz
cd mpd-version
In any case, you need:
a C++17 compiler (e.g. GCC 8 or clang 7)
Meson 0.49.0 and Ninja
Boost 1.58
pkg-config
Each plugin usually needs a codec library, which you also need to install. Check the Plugin reference for details about required libraries
Then run the following.
apt install meson g++\
libpcre3-dev \blur
libmad0-dev libmpg123-dev libid3tag0-dev \
libflac-dev libvorbis-dev libopus-dev libogg-dev \
libadplug-dev libaudiofile-dev libsndfile1-dev libfaad-dev \
libfluidsynth-dev libgme-dev libmikmod-dev libmodplug-dev
libmpcdec-dev libwavpack-dev libwildmidi-dev \
libsidplay2-dev libsidutils-dev libresid-builder-dev \
libavcodec-dev libavformat-dev \

libsqlite3-dev\
libsystemd-dev\
libgtest-dev\
libboost-dev\
libicu-dev \
libchromaprint-dev\\
libgcrypt20-dev

These are the library installations. You do not need to do this more than once.
# meson .
# meson . output/release --buildtype=debugoptimized -Db_ndebug=true

# meson configure output/release
# ninja -C
# ninja -C output/release
This is the equivalent of compiling.
# ninja -C output/release
# ninja -C output/release install
If there are no errors, you can now install.
Uninstall the old binary installation just in case.
The uninstallation of the mpd installed this time will look like this.
# ninja -C
# ninja -C output/release uninstall

# ninja -C output/release uninstall
# systemctl restart mpd
# systemctl restart mpd
# systemctl status mpd
# mpd -V
# systemctl status mpd
# mpd -V
If you don't get any errors with
, it's working fine. These processes can be done from a terminal on another PC using SSH, I think Putty or Tera Term can be used.
It is easiest to do this from a Linux terminal.
# systemctl status mpg
# systemctl status mpd What the heck is this?　This will show you the status of mpd in your server. This command will also give you error information if mpd is not working.

There are some minor settings, let's use them! I think it's a useful mpd client

And the URL will be as follows.

I installed myMPD most of the time ago, but it didn't work properly, so I installed nginx this time and it works fine.
I now understand what standalone means.
There is a setup, but if you modify the default, you will get an error, so use default.
It literally became a Dietpi Music server. The only problem is that it starts randomly selecting songs on its own and doesn't stop.

What is it? Is it my imagination? I feel like it sounds better this way. Maybe it's just my imagination,

new mpd 0.22.10 on 6th Aug

change log is show https://raw.githubusercontent.com/MusicPlayerDaemon/MPD/v0.22.10/NEWS
always same way compile by note of documentation of them. this mpd is 0.22.10 please carefully is not mpd 0.22.1
for up date mpd. please uninstall old version of mpd and this time is 0.22.9

new mpd 0.22.10 6th Aug 2021 / install 20th Aug 2021

What is the difference between the latest mpd and mpd before 0.20.9

The sound has improved, the album image has been imported better,
DSF files can be played without detailed settings.
You can play it without decompressing the compressed music file such as Zip or tar.xz. It's easier to manage music files.
Download the source, compile it and install it on your system. You can always use the latest mpd. With just a few tweaks, you can create a great music server.

Since debian Linux changed the method of compiling the source, it is not possible to compile the conventional method after mpd 0.20.9.
The mpd org site has detailed installation instructions.
Please install by referring to the site. The library will never need to be reinstalled, so save it on your server.
Also, the required libraries need to be installed each time. Please keep all the sauce
Necessary for uninstalling.

mpd update 0.22.10 install 20th Aug 2021 Nanopi-Neo2 Dietpi Buster

new mpd on 24th Aug 2021

The new mpd was updated on August 24, 2021, so download the source and compile it. It will be mpd 0.22.11. It's a small update, but let's compile it using SSH.
The compilation method is shown in the DOC of mpd.org, so look at this and compile the source. When the binary is ready, we will replace it with a new version.
Please uninstall the old version first.Compile takes several hours
After that, install a new binary.

mpd is being compiled using ssh

Play by mpd 0.22.11 on 2nd Sep 2021 by Nanopi-Neo2 Dietpi Buster

I fell asleep during compilation and my wife turned off the router on the server during that time, so I was wondering what was going on, but it was okay. First, uninstall the old version
I have installed a new version of mpd. You can update with systemctl daemon-reload. The album art of myMPD loads faster. The sound is good.

Very impotant Note: If would like to use NanoPi-Neo2 as Music Server please lean Linux first.if do not know Linux.

my desktop shown by photo

this is Main Amplifier always using these Amplifiers. 300B Single Ended Amplifier

always something to do ......

Note: I feel that the MPD has become 0.20.xx and the sound is very good. Since the version of mpd is the same as Moodeaudio, RuneAudio, volumio 2,
the trend of sound is the same. Because there is no interface on the contrary, the sound is also
It might be good. I do not have a UI, but I think that there is no inconvenience if you use it with other clients. "quite stable".
MPD is fully stable with Nanopi-neo 2 even RaspberryPi 2, 3.
I think that the sound trends are more vivid than those who do not use the dedicated OS for Music Server because there is gloss in the sound. Please do try it :)
It demonstrates sufficient stability. Although moodeaudio, runeaudio sometimes freezes, it does not freeze, this MPD does not freeze, you can listen to music stably for a long time.

Although I spend a lot of time, I think the sound is good enough for MPD alone. The problem is that the OS is limited.
It is a disadvantage that even if a new version of Linux is released like x86 Linux does not work.
It is a very limited standalone Music Server. In order to put WEBGUI, the ability to combine servers is necessary.
It is best to use a client. I think that it is a safe line to use Raspberry Pi. If you say
Why? Does "Raspberry Pi foundation" not issue Arm 7 or Arm 8 of PiZero? I think that Pizero is limited in use and limited.
There is not a good translation if it is cheap. There are lots of doubts.but try to build up small Music Server not so bad.
I am very happy using NanoPi-Neo2 with mpd 0.20.90 by ES9023 DIY DAC.
