Raspberrypi, without HAT, can't output SPDIF output because the clock that becomes the master clock is not output. SPDIF works without HAT in these one-board PC's
Only the Nanopi-neo2 and the Pine-64 are known at the moment. As far as I experimented, only these two models can be used. SPDIF is available, so you can use commercial DACs.
The sampling frequency of the USB DAC is up to 24bit 96kHz for the mid-range DACs, but using this method, you can use a DAC with a sampling frequency of 96kHz or higher. It does not require a HAT. The following is a list of

how to get sound from SPDIF from pine64 one borad PC
When I searched the net, it was mentioned that SPDIF works from Volumio2, but I didn't know how to connect it. But I didn't know how to connect it. And I found out that there is Euler port, as you know.
You may try to build it with reference to the drawing I made. I think you only need 1 resistor and 1 condenser. You can experiment with the value of the condenser. A beautiful hide pattern is output.
SPDIF output is coming out, so you can connect it to an external DAC. I've uploaded the video to youtube.
Although it is useful, but:) I was only able to use a USB DAC, so the use has increased considerably. The other I2S seems to be out too. The wave form is very beautiful.
Compared to Raspberry pi 3, I feel that the start up is faster. The sound has also changed.
The waveform of I2S is coming out nicely, and it seems that the master clock is coming out too. I need to analyze it, but I like this board very much. If you have a good DAC, you need to try it.
The low power consumption is a good point. However, this operation is possible only with Volumi2 OS. After listening to the sound for a day, the sound is good, the sound is clear, the RaspberryPi 3 has no SPDIF, so you need to connect a HAT to it.
Although these operations are not possible, in the case of Pine64, SPDIF comes out of the main body as it is, so it is a very convenient thing. I think that the jitter is also small. Because the master clock has come out, it is possible to connect the IC of DAC as it is.
Make a copy to Internal. Copy the copied mpd from ssh to /usr/bin/ from the command line, and you will be able to play the dop etc. smoothly. The sound also changes.
Now you have mpd -V, Music Player Daemon 0.20.6.
With one piece of PINE64 and a little processing, you can connect it to any DAC. They come to life.
You can enjoy music with Music Server and an external DAC. Of course, you will be able to receive internet radio as well. However, you need a LAN, and the LAN must have a line connected to the Internet.
About Pine64 :Music Server
1) The I2S signal is being output.
2) Master Clock.
3) It outputs SPDIF.
4) Dedicated OS is Volumio 2
You can pull out the SPDIF. You can use a DAC that can receive the SPDIF signal as it is.
.
This allows you to get the sound of any I2S/DAC or SPDIF. It also has a built-in DAC.
At the same time, it is possible to adjust the level of the audio signal.
.
With the above thinking, you can get a clean waveform from SPDIF with normal output.
.
You can get the signal out of SPDIF. I2S is also available, so you should be able to use it normally.

How to generate SPDIF in case of Nanopi-Neo2
Archive is based on Mr. Takajin's Volumio2 and mpd server files, and although Nanopi-Neo2 has a limited number of application sources, it will be available for experiments.
.
SPDIF output of Nanopi-Neo2
No matter how good TKZ's archives are, the non-I2S output seems to be an open collector, doesn't it? That's what I realized. On some website.
It was written. The remote control mentions that there is a pull-up resistor on the RX pin of the pin GPIO11 next to the SPDIF, but this is not attached to this nanopie, so it doesn't produce voltage under any conditions.
Trying this pin, that is, next to the SPDIF pin, I installed a pull-up from 4.7 K ohm +5V to this pin, and I got a dirty waveform, that is, let's put this pull-up resistor on it!
I'm going to add a waveform shaping circuit to this output with an inverter. Now you will get a satisfactory SPDIF output. Of course, I'll use TKZ's Volumio 2 which can do SPDIF. If you have the following
Circuits and waveforms. I think it's far from SPDIF's waveform to be exact, but I think I'll try it. When I connected it directly, I could hear the sound, but I think it's better to connect it after shaping the waveform because the level goes down.
I was able to do SPDIF with NanoPi-Neo2. :)
With a pull-up resistor installed, there is about 3Vpp of the output SPDIF waveform
.
GPIO output Although the waveform is dirty and the level is low, I confirmed that it can play noisy music by connecting SPDIF to it. So I added 2 stage amplifier. I added 2 stage amps by using inverter IC.
You can do this for less than 100 yen. In the output as it is, the playback sound comes out of the noise. However, this is a proof that SPDIF can do it.
Pull up resistor is a 10K resistor that is connected to SPDIF's output from +5V (red ■ ). One resistor is enough. But to be sure, a buffer is added. I'm using an inverter, but NAND is also fine.
Add a TTL buffer amplifier to SPDIF out for testing
.
Make an inverter, either Nand or Inverters. The power supply is TTL, so the power supply will be +5V.
.
My Mistake Pull Up Resistance
I thought something was wrong. First of all, it's the position of the pull up resistor. The position of pull up resistor.
It seems to be correct to put pull up resistor on the output because it is an open collector. And you don't need an inverter. So, I'll use a direct connection. You need to connect a pull up resistor to +B5.V as shown in the circuit diagram.
You can see a very beautiful hide pattern as below. By the way, when you connect a load, Peak to Peak will be lowered, so it's better to leave this inverter on.
If you don't care it, you don't need buffer circuit, but there is a possibility that Naopi-Neo2 will be damaged because of heavy load. I changed the position of the pull-up resistor without changing the buffer circuit.
Beautiful waveform...from NanoPi-Neo2 SPDIF
.
If you can't do ssh
Note: If you have more than one Volumio in your home LAN and you try to access a new Volumio2 via ssh, you cannot access it, or it won't give you the password.
You should be able to make a connection in this way. If you can't make a connection, first try volumio.local/dev in your browser. Click on the ssh icon just once. This icon will not appear on your computer even if you click it.
Since nothing works, just click once and SSH can be recognized by Volumio2 SPDIF.
It is wonderful to be able to use my own DACs in my neighborhood. In my case, using FN1242A for DAC
The price has jumped up a bit, you can't buy it for 2600 yen, what's going on? 30thMar 2019. I was going to buy another one if it was 2600 yen, but I decided not to. Before, it was exactly $3,000 with the heat sink.
I'm not sure if this is a good idea or not, but it's a good idea to buy the RaspberryPi3 B+ at Marutu. It is not the same, but why did you raise the price? In a one-board that is not easily accessible.
It's gone. This is a dirty practice. It's a monopoly business. By the way, the TOS link was invented by Toshiba, but TOS also means to throw. Fiber optic transmission methods are jittery, etc.
There is a risk of . It is also possible to adjust the frequency range of the signal to match the frequency of the device.
My DAC made on 1st Dec 2009 connected with Nanopi-Neo2 from SPDIF
3 digital input(SPDIF) + 1 analog input
Demonstrated SPDIF By Nanopi-Neo2
As a result, I added an inverter; even the output from the GPIO of the Nanopi-Neo2 can be regenerated, although the waveform is disturbed when connected to the load. I think it's better to add a buffer, and in my experience with the RapberryPi, if you add an additional circuit.
I had an experience of not being able to turn on the power when there was a risk of high temperature due to the burden on the body, so I added a buffer with a single IC if possible, even if it is just one resistor. The wave form became beautiful. You can see the pictures below.
I uploaded the operation status on YouTube.
.
The FN1242A is the DAC that plays the signal from the SPDIF output with my homemade DAC
.
Diverge this DTB, i.e. use it
I assume that people using Nanopi-Neo2 are also using Music Server, which means that there is a shared part in /boot/sun50i-h5-nanopi-neo2.dtb. If you rewrite /boot/sun50i-h5-nanopi-neo2.dtb, you can experiment with various drivers.
By the way, I think you should add the bind_to_address "0.0.0.0" somewhere in /etc/mpd.conf. This may prevent it from stopping from time to time.
I have found the ES9023 to be a good DAC. It is impossible to get it in Japan at regular shops, but it is possible to import it from China. The price is about 18,000 yen for 10 ICs.
The actual unit price is about 200 yen per unit, but if you go through an importer, the price will be about 2000 yen per unit.

The above is a single board PC, 64-bit version, very similar to NanoPi-Neo2. The price is low, so it is useful. I got data from various sites.
Recent development: I'm installing ninja, meson and other necessary applications for mpd upgrade on Nanopi-Neo2. Anybody? I'd like to see a feature on this.
I can't compile ninja 0.15, so I can't move on. meson compiles fine, but I'd like someone with some knowledge to show me an example.
I can't compile MPD because I changed the installation method, did something go wrong with the previous method?
See ninja install here Ninja install It will take some time to compile. .
Before that I will bring the source files from git, but you need to install git before that. Please refer to Ninja Build-org for more information.
Download the source. You will need to install the necessary libraries first. In this case I used Dietpi Nanopi-Neo2 Arm8 as the OS.
I downloaded mpd 0.21.8 for mpd for now. I found that the compile could be installed as documented on the mpd.org site, but the

The comments on the mpd org site also have a note of caution. You should install 0.50, meson is make instead of make and ninja is make install.
volumio2 rebuilds only mpd if you want to use the old application. I'm sure it will work. If you want to use USB DAC, you can use any version of volumio2.

Install OS on Pine 64 +A type
However, Akizuki's early 2-gigabyte Pine64 +A model number is old and there are very few OSs that can be installed on it. The new OS is dead. To make it a music server, sound will not come out unless the driver is installed.
Armbian can be installed, but there is no sound. There are no matching drivers. I used Dietpi Bullseye below. Volumio can also be used, but mpd 0.22.6
You can't use the latest mpd with . Dietpi Bullseye for Pine64 developed by the developer of Volumio seems to be good, but suddenly I can't decompress the tar xz file. I am troubled.
I tried to install xz-utils, but it doesn't compile. In other words, I couldn't decompress it, so I ported the file decompressed on another Dietpi to this Dietpi and then tar xvf ,,,,,,..xz again,
It turned out OK. It is an incomprehensible phenomenon. After installing many related applications, I was able to unzip. I'm not feeling well Dietpi...
So I did it again, but I still couldn't decompress the file with the xz extension.
# apt-get install xz-utils
I can't install it, so
# apt-get install aptitude
Install. next
# aptitude -y install xz-utils
I tried to unzip it, it was OK. First, unzip the source and compile mpd.
Can't ssh from Linux terminal
I think there are times like this. It's a terminal that uses only ssh, but the above image is the processing when it looks like the right.
# rm -R .ssh
If you do , you will be able to ssh normally.
If there are multiple Volumios on the LAN, it will be as follows.
# ssh root@volumio2.local -l volumio
You can access it by entering .
And I did a compilation of mpd, much shortened. It's mpd 0.23.8. From now on, we will build a music server.
Dietpi Pine 64 Bullseye mpd compile in progress
How to install Dietpi on pine64 and create a music server
The method is the one introduced on many pages. First, download the latest OS from Dietpi's website. Unzip it and install it as usual.
Install mpd and samba. Do not use Dietpi's method. It will conflict. Use Dietpi's OS as Debian. It will definitely work.
WebRadio uses the latest MoodeAudio Internet radio list. This also includes logo information.
The settings are getting rough. Detailed settings are not required, but basic settings make it convenient to use.
If you have a board, I recommend creating it.
1) Build samba yourself
2) Build mpd yourself
3) Install the libraries required to compile the source
4) Once you have successfully produced sound, refer to the Linux Audio Foundation and install Niginx and myMPD.
If you install according to the instructions,
myMPD will be successful.
