Pi 4B not working with Hifiberry DAC2 HD #357

Closed richardpringle closed 3 years ago

richardpringle commented 3 years ago

I had everything working beautifully before plugging in the DAC.

I tried some things from #296 to no avail. The aux output isn't working either anymore.

Here are the logs from the audio container:

The audio jack doesn't seem to work either.

... so the device is there as Sink #1 (which is different than in #296 where it was Sink #0). So it's being detected at alsa_output.1.stereo-fallback.monitor instead of alsa_output.dac.stereo-fallback.monitor.

(I have two Pis and two DACs so I don't think any of the hardware is faulty)

richardpringle commented 3 years ago

To update: when I hardcode alsa_output.1.stereo-fallback in the start.sh script, everything works perfectly (although I still get one of those 24.11.20 13:39:49 (-0500) audio E: [pulseaudio] main.c: Sink alsa_output.dac.stereo-fallback does not exist. instead of two).

I'm actually not quite sure what happens when I use the one-click-deploy with Balena-cloud. Before manually pushing edits, would Balena-Cloud have picked up new versions from this repo? Or would I have had to upgrade manually anyway?

And another question (feel free to get me to write this in a forum somewhere)... are there more configuration options? I see from this

that the resolution is 16bits and the sample rate is configured to 44.1kHz. From the datasheet, it looks like this board can handle a resolution of 24bits and a sample rate all the way up to 192kHz, is it possible to change these values?

shawaj commented 3 years ago

@richardpringle did you change the dtparams to say audio=off instead of audio=on ?

aandroide commented 3 years ago

i bet it's the latest pulseaudio update causing the problem. you can try to downgrade pulseaudio and restart: sudo apt install pulseaudio=12.2-4+deb10u1 libpulse0=12.2-4+deb10u1 pulseaudio-utils=12.2-4+deb10u1 libpulsedsp=12.2-4+deb10u1

richardpringle commented 3 years ago

@shawaj, tried, didn't help

@aandroide, I could downgrade, but that's just as much effort as hardcoding the name of the Sink

shawaj commented 3 years ago

@richardpringle with the audio=off set is it still sink 1 not sink 0?

shawaj commented 3 years ago

Aha I've spotted the issue I think.

The udev rules don't currently have an entry for snd-rpi-hifiberry-dacplushd https://github.com/balenablocks/audio/blob/master/udev/95-balena-audio.rules

Relates to #296

Will submit a PR to fix this later.

shawaj commented 3 years ago

@richardpringle until the PR is merged, you should be able to get this working by following the instructions here https://github.com/balenalabs/balena-sound/issues/377#issuecomment-752152387

shawaj commented 3 years ago

Duplicate of #377

shawaj commented 3 years ago

Closing this issue now in favour of #377

Necessary changes were pulled to the audio block in https://github.com/balenablocks/audio/pull/49

You can update by using git pull and balena push -c to rebuild if using balena CLI to build again without using cached images.
