Closed matqua closed 2 months ago
Hey, thanks for reporting and good work on details. First thing that comes to mind is power source. Can you please measure VUSB and 5v test points? Do they measure proper voltage? Does it stay stable during boot?

Playing audio through Mopidy or sox/play on the command line, the Pi will freeze or kernel fault/panic, sometimes taking out the network/ssh connection or freezing the Pi and requiring a power cycle.

I did have to do an apt upgrade before following the instructions (I could not get to the end of the instructions without the Pi freezing every time I closed the speaker-test)
After that everything seemed fine, aplay -l returns the correct values and the speaker-test command executed fine and would let me terminate it without any faults.
Next set the volume with alsamixer fine.
Next play a FLAC from the local SD card.
File will play fine but upon CTRL-C to play something else, faults/panics in the kernel log/console and the sound device disappears (aplay -l returns no devices)

Testing hardware/software
- I started testing with a Pi Zero 2W but ended up opening the case and sticking a Pi 3B+ on there.
- Initially it was a Pi Zero 2W using the onboard w5500 network connection, then with the zero's wifi
- Next I used a Pi 3B+ with it's onboard ethernet to speed up the testing, also to connect a local console over HDMI
- Power supply is a 100W Lenovo USB-C ( https://www.lenovo.com/au/en/p/accessories-and-software/chargers-and-batteries/chargers/4x21m37477 )
- Two different micro-sd cards
- Imaged with two different computers (Windows & Mac)

play FAIL sox: Sorry, there is no default audio device configured
Please note, this is with the Pi 3B+ still connected rather than the Pi Zero 2W. I don't see any signs of under-voltage occurring with the PI but thought I better still mention it.
Hey @matqua
Voltages look good, so that is out of the way.
I'm no linux expert, and looking through the logs, and it looks like at some point communication with the DAC fails, not sure if no ACK is the reason, or something else. It could be a bug in specific chip, or in the kernel driver.
Can you give me the specific command that triggers the bug and the command that pulls the error log (is it just dmesg
?). I want to try it on my board and see if I get the same result.
Do you happen to have Raspberry Pi Zero 1 to test the same? Asking, since I only have them in stock to do the test on my side.
Can you please also please check if DAC chip happen to heat up (finger test) and if there are obvious issues with soldering (solder bridges, or lack of solder) around DAC chip, as well as Raspberry connector.
@anabolyc No worries I'll setup a Pi Zero 1 W and document the setup step by step shortly

Hey @matqua I followed your steps and I can confirm the same kernel error message each time I play wav. I'll try to look little closer at what can cause it. In my case I never lost audio card itself in aplay -l
, so it is usable even after this error
Thanks @anabolyc
Yes the audio card is still available after using play or aplay. It is only when using Mopidy to play a file does the device disappear.
@matqua sorry, still looking into the issue. struggling to find time for everything
Hey @matqua I think I fixed the issue in the #6 . I tested with Raspberry Pi Zero. can you please test on your side, including other Pi models that you have.
Hi @anabolyc Looks good. Playing local flac files worked fine. Mopidy playing local flacs works well too.
Thank you very much! Great work š
@anabolyc I tested with a Pi Zero 2W
@matqua thanks for testing, I merged the PR and closing the issue.
