In this case you will have to download the script and install the application in the Root or General User. There are many paid applications that are available, and I'm sure this one is well done.

Raspberrypi digital out without HAT
Raspberrypi does not have audio analog out .because originally pwm out then low passfiler by active filter IC ,then get Audio.please see nex URL
Circuit Editor for Linux by Kicad is best
You can use Qtbsch for x86, but these applications are not available for Arm processor PC .so have to choose the other side of application.
Kicad is good for raaspberrypi work station. Kicad is family of KDE and Plasma so have to install plasma desktop into Raspbian.
$ sudo apt-get update
$ sudo apt-get install kicad
that's all.and you can use by Raspbian

Select your DAC from Overlay
For Raspberry pi, you can select the I2S DAC by editing /boot/config.txt. The driver is in /boot/overlays/ and you can use your DAC by editing the config.txt file.
You can use Nano or Emacs to edit them. In my case, I use Moodeaudio, which looks like this
pi@moode:/boot $ cat config.txt
Hifiberry is expensive in Japan, so I use justboom-digi, and the DAC is a homemade 198Khz 24-bit DAC. I'm very happy with the sound.

Circuit diagram creation application for Raspberrypi 4 Raspian
I tried using various applications for ARM, but all of them are difficult to use, isn't it easier to use? There are quite a few digital circuits, but I don't have a library of vacuum tubes. For X86, Qtbsh, Calduas, etc. are very good, but
On ARM, these applications can't be compiled, I think Kicad is good, but it's complicated, so let's use Inkscape here. I think it's very good. The library contains the parts of the schematic made with Qtbsch, which are commonly introduced.
I will use it. Since these can be saved as png originally, make a lot of parts library of PNG file. Cut out the schematic parts and save them with a PNG extension. After that, I will create it with Inkscape. It lacks the freedom of QtBsch,
Well, there is nothing that can't be used. Save the library as SVG or PNG. The save directory is under .config /inkscape /symbol.
Circuit diagram drawn with Inkscape h5>
For LibreCAD Arm
KiCad is complicated to create components, and even if components are created, detailed settings cannot be made. Basically, since it is CAD for PCB, I think that there is no freedom to create a circuit diagram. I think Inkscape is easier to use.
The component still needs to be crafted with other image editing CAD. There is a drawback that it cannot be saved as a part. There is no better CAD than QtBsch, but since Wine cannot be used on ARM PCs, it is an application for Windows.
cannot be used. Let's use LibreCAD. You can install it with $ sudo apt-get.
For Linux, copy the system library into the home directory. It will be .config /inkscape /~. The library opens commonly used schematics in GIMP and displays them in Inkscape.
Make a copy of the library from the schematic. The extension at that time is SVG. If you copy the symbol of the part into the symbol set, it becomes a library of electrical parts. Then draw a schematic using Inkscape
I will go. There are problems such as how to draw lines, but I think it is a usable tool. Once written, save it as SVG or export it as PNG.
The Tool closest to Qtbsch was found.
$ sudo apt-get update && apt-get install geda pcb gerbv
In other words, there was a gschema. It is a circuit diagram Editor that I did not notice after installing it before. You can edit the library lightly, and the lines are easy to stick, so it is a circuit creation editor just like Qtbsch. Lighter than anything else
Also, it is said that you can edit for PCB creation. I think you should make a lot of libraries. I think it is very good that straight lines are easy to draw.
It's basically GEDA. I think it's very light.
qcad is light.
No matter what you use, it's heavy and you can't get a straight line. Even if you can draw a straight line, the line doesn't connect. It's the same that the parts and the straight line don't connect. Kicad is complicated, it doesn't draw lines well, and it doesn't have individual parts.
I can't draw acorn-shaped vacuum tubes or circles clearly, the library is too complicated to enrich the library. In such a case, I easily lose to Qtbsch, and it is difficult to write on an ARM PC. LibreCAD and Qcad are very similar.
But I think Qcad, which has a lot of libraries, is good. The library can be created with Inkscape. If you're writing on an ARM PC, I think it's better to install 64-bit (formerly XP or Windows 7 PC) Linux on an older Intel PC and then install Qtbsch.
Qcad can be installed with $ sudo apt-get install, so please install LibreCAD and use it properly. I think Qcad is light.
Start drawing Qcad tube schematics
Editing with gEDA Circuit diagram creation
It is a circuit diagram creation by gEDA. This application is the lightest, but it is very difficult to write because I am used to Qtbsch, but I was able to create a circuit diagram. It was like this when I started using Qtbsch. The sym file is the part. The part creation application
No, so copy the base and delete it to make a new part. The attached parts are large and will protrude from the circuit diagram, so reduce the size to less than half and make the parts. First, open the file manager at the root and click on his sym file to open gschem.
There is an original part, so first delete it, leaving only the name. After that, I will patiently make parts. Save the most frequently used parts together in the tube amplifier parts folder (pseudonym). Close the root file manager and start from the beginning
I will draw a circuit diagram using the created parts. You can also draw a circuit diagram on an ARM PC, that is, Rasbian. I think that only long-suffering people can do it. I will make small parts when I have free time. The parts are
In my case, I saved the vacuum tube library in /usr/share/gEDA / tube. I don't think I'll use it because it's difficult to use, but I tried it.daefaults is black backside so can replace to white paper.
Not only Arm, but also foreign schematic editors are useless. If you want to write schematics in Linux, you need to use Qtbsch.
If you want to draw schematics on Linux, please install QtBsch on your x86 PC and draw schematics on it. If you want to draw schematics on Linux, you should install QtBsch on your x86 PC. It can't be used in applications that can't draw straight lines and intersections accurately.
I can't use it in my applications.
Rechallenge Pi-Zero W Music Server.
This PI-Zero is an Arm6, so it is slow and lacks a LAN port.
This PI-Zero is an Arm6, so it's slow and doesn't have a LAN port, so I need to add a LAN port to use it.
If you want to use it as a music server, you still need a LAN for the speed setting.
The Nanipi-Neo2 is much easier to use, but there are very few operating systems that can be used with this PC board, such as Armbian or Dietpi.
If you want to use it as a music server or for other experiments, you should use Pi3+B or higher version.
If you are looking for a music server or other experiments, please choose Pi3+B or higher version of Raspberrypi. We have found that small one-board PCs are very difficult to use.

Using Rune audio in the background using as Archilinux Music Server.
This is Runeaudio, a 3rd party version that is very heavy and the menus are not very detailed, but it uses Addons and Cantata to serve as a music server.
It's not so much that it's difficult to build, but that the menus are not very detailed, so you need to be familiar with the normal RuneAudio to get it to work properly.
So I use Cantata and SKYMPD together. I don't use Webui, only the mpd client.Music Player Daemon 0.22.4
Cantata is so easy to use that it can be used as a fully featured music server for Archlinux.
control by cantata and install radio by comand line sound is very much good archilinux sound
This operating system works by editing mpd from the SKY MPC and ssh command line. In other words, the detailed settings are configured using ssh. You can check the operation with runeaudio's WEBUI, but
I think cantata is the easiest to use. This is the fastest way to use RuneAudio. The sound is Achilinux sound. I use Moodeaudio as my NAS.
The Moodeaudio has a 2 tera hard drive, which I mount with CIF. If the connection is stable, this will allow me to transfer music from other servers to this one.
You can listen to music from other servers through this Archlinux music server.
# mount.cifs //192.168.1.2/a4C0-f0f0 /mnt/MPD/Music -o vers=1.0 iocharset=utf8
You can now load the music files from the NAS. For the internal share holder, type # chmod 777 /mnt/MPD/Music or similar from the command line to grant permissions.
so this version has HDMI can use monitor show Album picture. The sound of rAudio is very similar to the sound of Dietpi's compiled version of mpd 0.22.3. rAudio is Archlinux, but Dietpi sounds very similar to the sound of mpd compiled from source.
I think the previous version of rAudio sounds better, but it has the same tendency as Dietpi.
I've installed a new version of rAudio, and the low frequency sounds are much better.
The sound is exactly the same as the compiled version of Dietpi.
I'm not sure if this is a good thing or a bad thing.
You will need to build it with ssh. For internet broadcasting, create a Webradio directory under /mnt/MPD/, download Radio.tar.gz from outside and add it with Addon.
At first, I couldn't log in with ssh, but then I found a description in Github that said #root passwd is ros. This will allow you to edit via ssh.
New rAudio from github,
Rune Audio play DSF as Dop

passswd ros for root : new rAudio by ssh
Brand new rAudio github from

I've been using the FN1242A for a long time.
I've been using the FN1242A for a long time and it's a very easy to use voltage output DAC.
I think it's very easy to use.
I've been using the FN1242A for a long time.
The disadvantage of this Runeaudio (rAudio) is that it can't select music or stations, you can use SKYMPC to select music, Cantata is also fine.
if you have some problem mpd can not start .you can see error massage on WEBUI of RuneAudio.so use ssh can edit mpd.conf file.
The sound of this mpd and the mpd compiled version of Dietpi are very similar. It's hard to tell which is which in a blind test.
mpd should be compiled with the latest version of the sources.
I think that mpd has everything you need.The presentation of RuneAudio (rAudio) is very good.
a small shock can cause it to stop working.
RuneAudio has a disadvantage in that it is not stable enough to run in a distribution that stops working at all. In addition,
the use of new files for everything makes the library incompatible and unreliable.
This is one of the reasons why the development of RuneAudio has been halted. You need to be off the net to use it properly, and Samba is not perfect.
Since these applications have been removed, the RuneAudio music server cannot be used as a music server, and even if it could be used, it would not last long.
The sound is better and more stable with the Dietpi mpd version compilation. The unstable RuneAudio,rAudio. This has always been the case.
RuneAudio is not a regular version, but it can be updated with Pi Zero and a few. Pi4 is not possible. This is because it is not synchronized with Archilinux.
Zero, A, B, 2 and 3 can be updated.
When I actually update it, mpd is the latest 0.22.6. In Dietpi, it will be 0.22.6 depending on the compilation. I think you should also install emacs.
RuneAudio Linux is Archlinux so standalone music server.does not mount any NAS.
Update by SSH
RuneAudio and any Archlinux family does not have smbd so can not use as Music Server is bad point
Raspberry pi B play by mpd 0.22.6 update pi4 can not Update h3>
In the end, SAMBA cannot be done. It's a stand-alone music server. If you use Cantata etc.,
the music of the work station will be read. You can also use Cifs-utils to read the hard disks of other music servers.
So, load the hard disk currently mounted on MoodeOS. As an example, access with ssh.
RuneAudio: ~ # mount.cifs //192.168.1.3/A4C0-F0F0 /mnt/MPD/NAS -o vers = 2.0 iocharset = utf8
This will load the Moode Audio hard disk. The control uses SKYMPC. Cantata is fine. Let me introduce two images.
Load with Cantata. Basically, the settings are made using the terminal.
Since the WEB UI is heavy, display it + set it slightly.
The sound is the sound of 022.6 mpd. This is a unique sound of Runeaudio.
Introduce Raspberrypi pico
raspberrypi pico as micro controller・C/C++、MicroPython only can not use Linux
assignment of pico raspberrypi
If I left runeaudio alone, I think I'm updating it without permission, and I'm also changing the WEB UI without permission. Something is easy to use. However,
Samba doesn't work, so I use CIF to link with other servers. For Webradio, create /mnt/MPD/Webradio as explained before and unzip Webradio here.
You can build an internet radio by configuring with Addon. Webradio can be wgetted from my site or brought from other external sites.
please use slimjet browz for control .slim jet get from
Slimi Jet browzer see good
Volumio3 is not buster In other words, mpd remained as it was. Why doesn't Volumio use Buster? does not have "no development ability??"
It remains mpd 0.20.18. Better yet, I think it's better to use mpd 0.20.9. If this is the case, the DSF will not skip.
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
The cover can be displayed because there is a play list
Playlists are automatically generated by various methods such as Moodeaudio and Runeaudio, and each link etc. pulls in the carver image.
Generally, if you save it in a folder with a cover called folder.jpg
The image comes out, but I think that there is a hidden code in MP3 and WAV and it pulls in the carver.
I think it's also good to register on last.fm. However, these dangers extend to the hard disk
Because it searches, the cover may be displayed through Google from the label or Amazon, and if you are playing the music you are listening to in the room,
that is, the music on the hard disk, the same song will be displayed from the Internet radio.
What you hear is a very strange phenomenon.
Be sure to change the password as some people access it from the outside even if it is not connected to Wifi. OS is both Mood and Volumio2 Rune. The music server doesn't stop suddenly, so if someone accesses it or tries to fix it
It will stop in case of so it is recommended to change the password. Defaults are high risk and the contents of your hard disk can be stolen or deleted. be careful.

MKV youtube file sound conversion
MPD 0.22.6 can basically play anything. MKV used on youtube can be played in the same way as mp4. No format conversion required, although early MPDs couldn't play in any format
You can play the default mpd of Ubuntu Buter that is currently used in any format. Now MKV is easy to convert to MP4. If it can be converted to WAV, it can also be converted to DSF based on it.
The easiest way to use MKV is with VLC. The sound is very good even with MP4, and when played with Mood Audio, it is displayed as Mpeg.
VLC sound convert from MKV to wav
youtube MKV saved file play by MoodAudio 7.1
I think that people who have a site are in trouble due to the abolition of flash player.
I think the person who owns his site was very confused by the abolition of Adobe Flash Player at the end of 2020 last year. This was a fairly complicated script, but I played it using an embedding called fladance.
It was said that it can be played in HTML5. That said, you need to study HTML5 and you also need an application.
There has always been an easy way. So let's introduce it here. Youtube has a copyright relationship, so permission is not given and I upload it to Youtube by trial and error.
It usually doesn't go smoothly. h4>

This video needs to be edited with Avideomux because the same MP4 could not be played on the smartphone MP4. I got an error in the mp4 before edit.
For that purpose, edit the video to fit the website.
I'm using Avideomux of Fedora core Linux very much usefull application for edit video
If you do not edit the video taken with your smartphone to introduce the video, you will not be able to introduce it on this site and an error will occur. I edited this operation in detail more than 5 years ago.
Recently, thanks to youtube, I didn't edit these and just uploaded the video to Youtube. Since the flash player has been abolished, it is necessary to edit the video again.
In my case, I use Avideomux. I use it to edit AVI and MP4.

I won't introduce it here, but it seems that there is also a product version called Raspberrypi 400. I will introduce the link.
Because it is a collection of Benkei, the performance has not improved. It is unavoidable that it only operates slowly. Kano seems to be Raspberry pi OS developed by micro soft?

RuneAudio cannot read music from other servers because SAMBA is not enabled, so mount it as follows.
RuneAudio: ~ # mount.cifs //192.168.1.2/6e24-5d74 /mnt/MPD/USB -o vers = 2.0 iocharset = utf8
//192.168.1.2/6e24-5d74 is another running music server or NAS. In my case, I use a 2tera hard disk for Moode Audio, so I use it as a music source.
Arm of runeaudio archlinux has a poor library and is useless It is difficult to download the first OS and then modify it, isn't it?
This OS is up to now. I don't think Archilinux should be used just because it sounds good on an OS with a lot of instability that changes every day,
which is the reason why development has stopped.
I think it's good for making sounds, but I think it's a good idea to install a new version of Runeaudio each time.

When I searched for
, I noticed that there was an x86 Emultor. It has Box86 in pi-apps.
I thought this was an emulator for Arm, and when I searched for it, I arrived at this page.
Please try it first. Let me do it too. Now that QtBsch has the potential to work, it's great news. With this, various applications for windows may work. may be ???
I think it's justified to use a Linux application for x86. Well, what happens, it takes a lot of time to install.
Mainly games for x86, but there is a description that it works quite well. Now if the schematic editor for X86 etc. works, you don't need other workstations of Raspberry pi.
install by git much better then source install because take a time to install library. so much better use git.please install git before start github.

how to use Slimjet
Slimjet used in multiple languages. I will write it in the edit of the site like this, but to make an English version, save this as txt. does not have a menu to open the file in slimjet, possibly
Perhaps there will not be found. Enter the "/" slash in the URL entry window to see the directories on your PC. Find the desired file in it and translate it into the desired language.
I can point out some differences in translation, but it's better than Google. Right-click on the screen and you will be asked if you want to translate, so select the language. This will give you a better translation than Google.

Installing Emicrock for win32 on Box86.
I installed emiclock using Winetrics, or to be more precise, using the Wine file manager menu. The application is emiclock for 32bit.
Download the 32bit application for windows and save it in the holder. After that, just select the application from the menu. The installer came up. Maybe you can do it.
I thought. After installing it, emiclok was ready. It stuck to my desktop. Thanks everyone, the instructions on the Qiit site and well, it was helpful.
This is good enough for me. I'm going to go ahead and install various applications. What did you do in the end? A spell
sudo systemctl restart systemd-binfmt Is this the one you installed? I checked the starters with this and it was starting fine.
Traduce by Deepl
emiclock is working properly.
Refer to Qitta's website and install winetric and others.
When you install the software, you will see icons in the menu and you can follow them to install the applications.
Bsch does not seem to have an icon, so you will need to create one through the path.
I'm not sure if you have to install it each time, but you can search the net for a library of symbols.
I have a reasonably updated version on my site. VA is Visual Analyser, which is a 32bit application recommended for Linux Wine.
Icons and configuration are reasonably well done. I will try to make it cheaper to use.
Wine menu show above.

Visual Analyser for windows 32 bit and Linux 32 bit version.
I've been using it for half a day, and it still doesn't work very well, sometimes it just freezes. I think they are useful. I'm not sure if it's a good idea, but it's a good idea.
I think it's great to be able to draw schematics smoothly and 100 times more flexible than Kicad or other drawing applications.
I'm using the windows 32bit version of the application.
I'm using a 32 bit version of the application, so I can run it just fine.
I think you should use a larger monitor and a regular PC key board. I'm using a 16" LCD. If you have a little patience.
I'm sure time will tell if the Windows version of Office is stuck or not. I think it's good enough to be used as a toy for both children and adults.

Installing Bsch on Raspberry pi4.
Here is the latest version of Sugyodo's BSCH binaries and library 6.2021.
First, download bs3vp16050rtl. Unzip it and save it in the wine directory. wine maneger will specify the file. First, install the included RUNTime called C++. Then
Install the Bsch book file, RUNtime is not specified on the file, Microsoft C++ will be installed when RUNtime is installed. This is RUNTIME. Then install Qtbsch.
. When the installation is complete, a BSCH window will open, and you can open an existing file or create a schematic. This is the BSCH for Windows. You can now create a schematic.
By the way, you need to install LCO and other Bsch families each time. You can install them each time. It's not clear whether it will work normally if you pass it through, but it's a good idea to use it every time you install it.
I think this is a good idea. This is the first time that Bsch can be used freely on Raspberrypi Raspbian Buster.
You can write it like this.
Bsch 32bit windows version.
GMPC and Raspbian Buster
It's a great breakthrough to run Bsch on Raspbian Buster, thanks to WineHQ who developed wine. I think WineHQ has done a great job.
It's great to be able to draw tube circuits and digital circuits on the Raspbian Buster with the monitor attached, just like on an X86 PC.
I've been using the Raspberry Pi4 for a while now, and I'm sure it will be able to run Windows 10 soon.
I can use it as a SUB PC like this without any problems. No power consumption.
You can watch Youtube and of course Netflix and Hule. I've been using it for a few years now.
This is definitely a useful PC for children.
I was able to install photo shop .Itune and Mario Bros game for Nintendo. This part was edited on 24th June 2021.
This is the Microsoft version installed on the Raspberrypi 4 Rasbian Buster by Wine 5.
I'm using Visual Studio Code to edit this. I'm not sure how to use it yet, but Visual Studio Code exists for Linux, but not for Arm.
When you install Wine, you can use it on the Raspberrypi4, and to install Bsch, you need to install RunTime, which is also a free C++ application from Micro Soft.
This is a recent development by Micro Soft, which is aware of Linux. I'm not sure if this is a good thing or not, but it's a good thing.
Now let's try to transfer the file from the Raspbian Buster terminal using GFTP. I used VisualStudioCore for editing, but it was too slow,
so I used BlueFish. There is no problem with the transfer, but other operations are a bit sluggish.
Since I am using LXQT, it might be better to use LXDE or ICEWM, or even JWM or Flwm. The window manager needs to be lightened.

TASCAM Hireso editor Let's try it out .
First things first.
Prepare the WAV file and transfer it to the Raspberry Pi4 B's Raspbian Buster using SAMBA.If you have SAMBA enabled, you can download the file from a music server.
Start up TASCAM's Hi-Res Editor. Import your music files. Then EXPORT. You will be asked what you want to set it to, so set it to 2.8 Mhz.dsf.
All you have to do is EXPORT. Depending on the capacity, the conversion will be done at a very slow speed. Reading takes a lot of time,
but EXPORT also takes a lot of time to make DSF.convert from wav to DSF is a lot of time to take .x11 64bit do about a half of minute but this Case

case of Nanopi-neo2 Music server OS is Dietpi Buster
I still have a few hundred albums left, but I'll put the cover image in the folder
she is best looking for any Music Server
this is only sample for help configure file of mympd.conf located /etc/mympd.conf
Under Current by Bill Evans and Jim Hall
Modify Nanopi-neo2 as above, just attach one resistor and capacitor OS uses Dietpi Buster
This is the only one attached and removed I2S DAC then add header terminal
Basically, the music file of the PC using NAS or Raspberry pi is mounted and the music file is read. Playback is performed on this Nanopi-Neo2. You can also attach a DAC to the Nanopi-neo2,
Since it has an SPDIF output, you can play it by connecting it to your existing DAC with an SPDIF input. In other words, you need an external DAC. In my case, I use my own 24-bit 198 Khz DAC.
Let's try install windows 11 into Raspberrypi 4
Windows 11 for Raspberrypi4
Currently, raspberrypi4 moodaudio is installed. I make sounds only occasionally, what are you using it for? I am using it as a file server. Because it's hard to use,
I don't think the sound is so bad, but I use it quietly as a NAS or file server because it gets stuck in the GUI. The hard disk has 2 terabytes.
The sound source is used by producing sound from the Naopi-Neo2 Music server on another LAN. Since Nanopi-Neo2 has few ports etc., from the SPDIF output of Nanopi-Neo2 to a self-made DAC
I'm connected. For Nanopi-Neo2, Dietpi Buster is the OS. mpd has been compiled and is now 0.22.11. The mpd Client is controlled by using Cantata and SKYMPC of myMPD PC together.
mpd is 0.22.11. When the latest version comes out, I compile it and always use the new version of mpd. After 0.20.X and above, it became possible to play music files with many extensions.
You can also play MKV and ZIP. ZIP can be played even if it is solidified without decompressing anything. That is the feature of the new MPD. DSF can also be played as a DoP without writing a special script.
Voumio2 still uses old UBUNTU, so mpd has not been updated, MoodAudio is a version of MPD close to the latest version. In my case Moodaudio is used as a file server
I think it is fully functional.
Recent Raspberry Pi: Since it is not an application shop, Raspberry pi without a master clock has no purpose to use, for the time being, 3 units are always operating, but a file server and
I use it as a music server. I've been unemployed due to the influence of Corona, so there's nothing I'm looking for in Raspberry Pai. I don't need expensive DACs, and I have DACs I made a long time ago.
If that DAC breaks, it will run a raspberry pie music server. Raspberry Pai 4 has SATA hardware 2 Tera, so run that file with the latest Nanopi-neo2 mpd.
With only one music server, things can be used satisfactorily. Nanopi-Neo2 is a weak but very good music server. The controls use SKYMPD and Cantata. There is a self-made DAC Nanopi-Neo2
I am enjoying music by transferring with SPDIF of
. This is also a technique that cannot be done without a Raspberry pi4 file server.
Edit images with Microsoft photoscape
I am editing an image using MicroSoft photoscape. You can do the same with the Raspberry pi4 Raspbian buster. The application is installed using Wine.
There are various items, so I think it's good to master them.
Old version of Raspberrypi B+ does not play new Volumio2 so using ver old
Rune Audio new version 0.6
I can create Rune Audio from Archilinux, but I don't have such knowledge, because Archilinux has a complicated method and may damage the hard disk, so I made it a general method. prize.
Here is how to download a general image. First, download the image from the link introduced and burn it to a micro SD.
Let's bake using Echer. The partition is then spread with gperted. This time it is Raspberrpi B + of the old board. Burn Rune Audio0.6 to this.
Remove RaspberrypiB + from the music server and repair it. I installed the latest version of Volumio2, but Samba share was not recognized and saved, but I could not play it.
This music server will be provided to acquaintances. Currently, there are 3 music servers running at home, so this is enough. There are two Nanopi-Neo2, two Raspberry Pi, and one Pine64.
SPDIF output is 3 units. Only one DAC is installed. SPDIF connects to a self-made DAC at the output. This is enough. DSF is for PCM only because there are not many sound sources and there is no chance to hear it.
A PCM sound source is sufficient.
Rune Audio 0.6 new version does not work so this is old version 2020 h3>
mount is used by mounting a temporary NAS from Moodeaudio's hard disk. Rune / Archilinux does not enable samba, so mount it using cif-utils. You can use it with this.
Or attach hardware or USB memory to USB to play music. WebRadio imports WebRadio from the outside.
The method is as introduced earlier. First of all, play music by mounting the hard disk
mount.cifs //192.168.1.3/6e24-5d74/ /mnt/MPD/NAS -o vers = 2.0 iocharset = utf8
The new version did not work. This time it is Raspberrypi B +, so it may work with other versions.
How to use fdisk
# fdisk: /dev/mmcblk0
Welcome to fdisk (util-linux 2.30.2).
The contents set here are retained only in the memory until the write command is executed.
Be careful when using the write command.
Command (help with m): p

If you have been using Linux for a long time, you will understand. It's the Linux world that starts with cutting the HDD partition.
This is an example of micro SD, but the same is true for HDD disks. This will delete and create a sector. You can see it by looking at help. Set with the
command. Delete is d, p is a command to look inside the partition. This technique is the same for DOS.
And cut a new partition with n. Then cut off from the primary. You will be asked interactively how to do it automatically
Please decide the address of the partition. The sectors are numbered and the memory is set accordingly. After setting
It will be saved q just leaves this fdisk. Hand it over to the kernel with w and save it. At this time, an error code appears on the screen
Since it may appear, a note will be issued at that time, that is, an error will occur if it does not connect well with the kernel of the PC.
Since you cannot proceed with the process after that, please reboot the PC to make the same screen. I think it's normal.
You can also fill the partition with this operation, but here, do not use this and use Gparted again to set and format
Please go. Even if you can't format it with Gparted, it often works well if you delete it with fdisk and reassemble the partition.
You can use fdisk and Gparted to initialize HDD and micro SD. I think you should try it many times.

Raspberrypy B and Pi-Zero 1000Bps LAN adapter
People who have Raspberrypi B or A (without LAN), Pi-Zero people will feel the need for LAN and the LAN speed is slow at 100 Bps with old-fashioned Raspberry Pi.
Pi-Zero is about 1800 yen including tax with this LAN adapter Yamada Denki. You can buy B + from the beginning, but if you don't know, you can get 1000bps with this adapter.
If you have trouble with skipping sound, just plug this adapter into USB to improve speed.
The built-in LAN port is no longer needed. I think it is convenient and useful for Pi-Zero.
How to use VNC control
Run Raspbian using VNC
First, let's show the image you are using, you can run Raspbian.local on your main PC. It's very easy, so I think you should try it. I think you can use Raspberry pi more than 120% h4>
It looks like it is controlled by Fedora Core 26 64bit using VMC
By doing this, you can watch and operate the games installed on Raspbian Buster and the videos of Hule and Netflix from the main PC (Windows, MAC OS, Linux WorkStation. Of course, you can operate anything.
"Settings" of Raspbian Buster of Raspberry pi4 --- "Settings of raspberrypi" Then set VNC to "Enable" This operation is set on the PC side of Raspberry pi4.
After that, please install "VNC View" on the client's PC side. By doing this, if you are connected via LAN, you can study Linux using VNC even on a Windows PC.
The game can be a slow game, but it seems impossible to play the video. The image quality is poor and the movement seems to be sluggish.
You can check the operation of VNC. Applications installed on Linux and other operating systems
I think it is better to uninstall and install a dedicated and highly compatible application. You don't have to use Samba to transfer files, etc.
If you use it as a server
Internal editing is ready. On the Raspberrypi side, there is no need for a monitor, mouse, or keyboard other than the initial stage. Please try it.
I think it will be an easy-to-use TOOL depending on how you use it.
If the menu is displayed with $ sudo raspi-config, enable VNC. Open a terminal to this and execute.
When the menu is displayed with $ sudo raspi-config, enable VNC. Open a terminal to this and execute.
Download and install the VNC View application for each OS Install this on your main PC
Just show you how to by 2 of photo's and please try do it. very easy to do.
this setup by Raspbian Buster by small PC
this configure set up ssh firstname.lastname@example.org
The above image is an image taken from a Linux PC, that is, a shot screen taken from the Linux screen of Fedora Core 26
VNC can be operated remotely not only on Linux terminals but also on PCs with different OSs.
If you can not install it with the initial settings, I think that it is a very useful TOOL when the teacher will teach you remotely.
Music server and myMPD that can be done without Raspberrypi
mpd 0.23.2 and myMPD by Nanopi-Neo2
myMPD by Nanopi-Neo2 Dietpi Buster on 22nd Nov 2021
In the case of Nanopi-Neo2 etc., it is necessary to develop independently using Dietpi, Armbian .
Ubuntu are not supported. That's a risk, but depending on how you think about it
You can create a music server as shown above. In the case of Nanopi-Neo2, SPDIF can be output directly from the port, so you can use your own DAC. Since the master clock is out
You can also use a DAC that is normally distributed. It is not necessary to rely on I2S DAC, but you also need to compile MPD etc. by yourself. You can also use the new MPD.
apt-get install samba-vfs-modules Bullseye is a debian-generated Samba error-free, invisible failure, unauthenticated issue. Therefore, files cannot be exchanged.
I was in great trouble. The same is true for Armibian, and when I saw it on the net, it was avoided and I was in trouble because there was no report.
If you install samba-vfs-modules described in the blog of the person who moved to Atlanta, USA
It can be avoided, but the entire OS will be enabled, but I don't think it can be used.
As I said somewhere, the Samba error reminds me that sharing would cause security issues and would be abolished. So I have to avoid it in some way
Debian isn't too lazy, Samba just made sharing unusable, not an error. I don't know what to do with this, but it's pretty good in Armbian, so Armbian got his 4.8.
Maybe you're still using it. If you renew anything, you will not be able to reinstall it. The previous version is python3, but this Bullseye is python 3.9, so the previous version is
I can't compile even the source.
winbind: Is it a shared program to be embedded in Samba? The conventional Samba had these built-in. Starting with 4.13, this winbind is required. In this application
It will be possible to use it in the same way as conventional samba. For CentOS
yum -y install samba-winbind samba-winbind-clients ← winbind installation
It is said to be
, so you can find an application that does the same thing in Debian. There are other settings.
myMPD + Nanopi-neo2 Music Server 30th Dec 2021 just show you good
This site has the following page, so please have a look there. Use the new Bullseye.Next Page
Raspberry pi4 comes with Bluetooth
Moodeaudio has a Bluetooth function, let's use that function and pair using a smart phone. Music stored inside the smart phone
The image shown below is the one that is transferred to Moodeaudio and played from the music server. Sound can be played normally.
It goes without saying that Raspberrypi has various other functions, and it is a music server that you can use freely and conveniently.
Moodeaudio is listening to music stored inside the smart phone
Volumio3 is very fine and Music Server by Volumio3 is very good and mpd is 0.21.18
CEO Raspberrypi doesn't mention anything
However, it is said that there is a global shortage of goods, and it seems that production has been suspended due to the shortage of goods.
This is true. The price is rising accordingly.
In the market in Japan, the arrival is undecided at retail stores, major bases RS, etc. until April. At least no lathberry pie is sold in Japan. This is said to be the effect of Convid-19.
In addition, there is a fact that it is used for medical equipment related to the heart and respiratory organs, and it is said that the spread of embedded Linux equipment is related to the shortage of goods. Amazon and others sell at several to 10 times the regular selling price.
If you stick only to the music server, it is a fact that you can make a music server with Nanopi-ne02 at a low price even if it is not a Raspberry pie, and it depends on your ability as a hobby.
The question is to study Linux. I'm an active office worker over 71 years old, a home experimenter, and a garage maker. It is even poorer. But in a world where you can build your favorite audio cheaply
Is it because of mpd? Mpd will make the sound even better. Let's get better sound from your music device amplifier and speakers
Nanopi-Neo2 mympd and mpd is 0.23.6 on 6th May 2022
Nanopi-Neo2 Music Server mpd 0.23.6 new version mpd
Raspberrypi Zero W by Bluetooth with MoodeAudio Sound depends on the DAC, but I think it's an easy-to-use method.
Moodaudio 8 by old Raspberrypi B and show by Microsoft Edge Linux version
Moodeaudio ver 8 is a problem that samba share cannot be done
MoodeAudio 7,8 cannot samba share, so the shared part can only be USB or mounted. That would reduce the convenience.
This is because Version 8 uses Bullseye as the original OS, so Samba cannot be used. However, other mounts are not possible. When I tried to mount it, it was rejected
Why? Speaking of which, Debian Linux, the OS that is the basis of this OS, can install Samba from the new Linux distribution, but it has been removed.
I'm guessing that the Samba share was removed because the number of people using Linux for the music server increased and the security deteriorated.
This has been an OS that cannot be shared by Archilinux for several years. After migrating from Buster to Bullseys, I realized that Share was not possible.
So I will use the wsdd method based on the same experience as Armbian Nanopi-neo2. Since it will be 100% successful, please use this method to secure the Share part.
I will post the Link, so I will install it referring to it. You can also transfer files with Moodaudio 8.
By doing this, you can mount the NAS and access it from your PC, please try it, and you can use many internet sites with Cantata.

Using Moodeaudio 8 with Samba Share mpd 0.23.5
You can use samba share with MoodeAudio 8
Production of Raspberry pi has stopped. It is the influence of Corona Covid19. The whole world is spoiling China. It's very regrettable. The world is flooded with Chinese products and problems are piled up.
The countries and the United Nations that do not resolve them politically have finished their role. Production of the Raspberry pi has stopped worldwide. When will the Raspberrypi 3B + be resold?
I think it is the responsibility of the nation that even Japan has no products made in Japan due to the fact that the manufacturing industry in the world has left it to China. It will be very important to be reviewed.
If you use it only for music, Nanopi-Neo2 is enough. Two music servers made with Nanopi-Neo2 are in operation. Call for early remanufacturing of the Raspberry pi. A set of hugs by these turmoil
Sales and price increases should be avoided. What about the plan to give PCs to children around the world at the lowest prices? I just want to avoid raising prices with human ego.
moodaudio 8.x uses Debian Bullseye
Bullseye OS has disabled samba. Therefore, I made the Shre part unreadable. Here, we will incorporate a server called WSDD into these servers. As a result, even with Moodeaudio 8, NAS mount
is now possible. I think that WSDD will be incorporated by Default in the future. This integration makes it easy to enable Samba. Please try it.
I think this is good news for Debian-based operating systems. I use Fedora Core 26 for my workstation. It's been a few years since the end of support, but I was using a technique other than Samba. External application
I don't know if it's called
or RunTime, but it came with an application other than Samba. Well, it is a Debian system, but I will tell you the method below. I think it's good news. It is obvious when you look at the image above.
There is an example of this process seen somewhere. I'll give you a link so you can test it yourself. There are no particularly difficult settings. Just in case, I will write it as a memo here as well.
solution for samba
Bullseye + cantata Music Server and Samba
1] Connect to it directly in explorer by it's ip address - for example:
 Win10 can use mDNS to connect to the server - addressed by it's host name with a .local attached at the end:
Just make sure avahi is installed on Ubuntu:
sudo apt install avahi-daemon
If you really want Win10 to be able to discover your server you really only have 2 options:
[A] Win10 uses something called WS-Discovery ( WSD ) to discover hosts. Samba doesn't do WSD but with a bit of work you can make it work:
Download the folder:The person who stated that it will work with a few operations wrote the method. Download and install wsdd.
Rename the python script:
sudo mv wsdd-master/src/wsdd.py wsdd-master/src/wsdd
Copy it to bin:
sudo cp wsdd-master/src/wsdd /usr/bin
Copy the systemd service file to /etc/systemd/system:
sudo cp wsdd-master/etc/systemd/wsdd.service /etc/systemd/system
Reload the service:
sudo systemctl daemon-reload
Start the service:
sudo systemctl start wsdd
Enable the service so it starts at boot:
sudo systemctl enable wsdd
[B] Enable NetBIOS on both Win10 and Ubuntu - This is something Win10 is trying to get away from since it considers it a security issue:
In Win10: Control Panel > Programs and Features > Turn Windows features on or off > SMB 1.0/CIFS File Sharing Support > SMB 1.0/CIFS Client.
In Ubuntu: Edit /etc/samba/smb.conf and right under the workgroup = WORKGROUP line add this one:
server min protocol = NT1
You would think that a simple restart of the service would be enough - and it might be in your case:
$sudo service smbd restart
But NetBIOS is a relic of a bygone era and you might have to reboot the box.
NetBIOS is a nasty thing to work with so you may need to do some other tweaks to get it working.
Moode Audio 8 + wsdd samba music from NAS using samba
This is the screen for operating Raspbian Buster from Fedora Core Linux using VNC Viewer. Wine is installed on the Raspberry pi side, and the light application for Windows is
It is ready to work. The image below is the login screen. Basically, if you can see the network, you can use VNC.
It is in the state of Network, and it is not displayed because Windows 7 is not turned on. In the case of Bullseye, it will be a little different
If you are using Raspbian Bullseye, you may not be able to do VNC without installing wsdd. Please understand that. First, install WSDD and configure the settings
I think it will be after
Recently I use Google Translate. Please understand that the meaning may not match.
I hope Google's accuracy will improve, but it seems impossible. Thank you for your understanding.
Raspberrypi B+ Music Server
Raspberrypi B + Music Server Old element 14 Raspberrypi B +
Sony does not manufacture any new products, so I don't think the domestic version of Raspberry pi will be available in stores for the time being. If you only have a music server, you can also use Nanopi-ne2, so please use that.
on 20022 july , due to the influence of Covid 19, Raspberry pi B + 3B + Zero w 4B is no longer sold in Japan. Production will be discontinued for several years.
It is an unstable country with unstable domestic politics and no political party to dominate. Prices are rising, and it is regrettable that Pfizer's vaccine will kill more people. Japan will end as it is.
This music server can be manufactured with a commercially available DAC hat, and can also be used with a high-end DSD playback board. Since the latest version of MoodeAudio 8 or later uses Bullseye, knowledge of Linux is
Required. I don't think you can install and use it sufficiently unless you can type at least commands. Even old people can do it, so make some effort. In the output part in the circuit
Please add a non-polar capacitor of about 2.2uF 16V to the output. Also, if you have Zero W, you can easily use Bluetooth with Moode Audio.
Since it is a Bluetooth receiver, you can operate it in the same way as the sound bar. Now you can pair your smartphone with your smartphone.
I'm so sorry about English etxt is traduced by Google from Japanese tetxt.
Music Server schematic diagram for Raspberry pi B+
Whoever made the Raspberypi Zero is either stupid or dumb
Even if it's made small, it's difficult to build, and since it doesn't have a LAN port, you'll need to attach a LAN adapter. The same goes for A+. why did you make something like that
Should we? I don't understand, I didn't make it smaller to improve performance, I just made it smaller by removing the stuff that came with the Raspberrypi B3+. It's good for use as a board
Because it is small, if you attach a peripheral device, it will be too big and it will not fit in a small case, so there is no advantage.
Nanopi-Neo2 is small, but the LAN port and USB are normal size. Moreover, it is 64bit, and you can work without any inconvenience. It is because GPIO is divided into two systems
It's easy to work with, and it's great that the master clock is available. The raspberry pi does not have a master clock, so if you want to make it a music server, you have to use limited hardware.
The external attachment is not too large. The Raspberrypi 3B+ is a masterpiece, but the others are just garbage. It is also out of production due to the corona virus. Dreams like this
Is it over? Mr. Sony, please take care of him, Mr. Raspberry Foundation. Sony cannot make new products because it depends on China.
This sentence was translated by stupid Google.
only one I have Raspberrypi Zero w (zero inside) as Music Server with I2S DAC
this is last one which I have pi4 but sold to Germany Audiophile . 12nd Aug 2022
It's August 2022, and there are no longer any normal-priced Raspberrypi boards in Japan. At prices more than 10 times higher than the normal price and retailers who own a large amount
It is now available for sale. Even in the regular version, the name is changed and the price is raised to a commercial level. Dream children's Raspberry Pi's gone, with adults egos
Low cost boards are gone. I think it will take 10 years to get back to normal. In the meantime, will it be out of print, and will the dream PC disappear in a dream?
There are boards (HAT) that can be used for 4G such as LTE boards, so if Raspberrypi is resold, it is expected that it can be used for phones. but no available.
The United Nations no longer exists if the WHO does not question China's full responsibility for causing the corona Covid 19 and fleeing. The earth has become a satellite of the ego.
In a sense, has the earth entered its apocalypse? It is unfortunate. Japan is also anarchy. Koreans in Japan can do whatever they want. Where are USA's powers going?
Is it wrong?
A Raspberrypi is required to create a music server, but if you understand Linux even a little, you can use Nanopi-Neo2, Beegle-bone, or even Aruduino. Traduce by Google
I think that ony's inability to announce new products is closely related to the fact that these official versions of Raspberrypi are not being sold.
Sony's demise and Raspberrypi go hand in hand
Am I the only one who thinks they might be related?
