Possible DWC I2S kernel driver issue for RPi 5 #5747

Describe the bug

I'm on a RPi5 4GB running Raspberry Pi OS 64bit Bookworm and my application hangs on ALSA function snd_pcm_readn when I try to read and write from and to the same device. This occurs on an IQAudio Codec Zero sound card and on a HifiBerry DAC+ADC Pro as well. When I select a USB sound card as the output and one of the others described for input everything works like it should.

Here's my code:

I have the same issue when I switch to PortAudio as an ALSA wrapper. Then my application hangs on Pa_ReadStream. And I'm using one of the basic PortAudio examples (paex_read_write_wire.c) as the basis of my application.

The issue also occurs when using alsaloop or aplay and arecord in 2 different shell sessions.

As soon as I start aplay, arecord exits with a 2221 input/output error and the HW pointer stops moving. This exact behavior is also seen when using a HifiBerry DAC+ADC Pro on the RPi5.

For. more information see the issue I opened in the alsa-lib repo and PortAudio repo.
And the raspberry pi forum.

Steps to reproduce the behaviour

Start arecord in one SSH session with:
arecord -f S16_LE -r48000 -c2 -D plughw:Zero,0 -F0 --period-size=256 -B0 --buffer-size=4096 test.wav
and aplay in another with:
aplay test.wav -f S16_LE -r48000 -c2 -D plughw:Zero,0
And a 3rd SSH session where you watch the status of the capture with:
watch cat /proc/asound/card0/pcm0c/sub0/status

I can reproduce your findings.

pelwell · 2023-11-28T12:21:56Z

There was a bug in the DMA configuration, which I had to add to the 6.1 driver. Things have changed significantly in newer kernels so I need to review my changes in rpi-6.6.y etc. (and possibly back-port some of it), but for now #5757 should fix rpi-6.1.y.

Wait about an hour for the auto-builds to complete, then you'll be able to install a trial kernel by running sudo rpi-update pulls/5757.

nodemand · 2023-11-28T12:34:48Z

Thank you so much!

gtrainavicius · 2023-11-28T13:03:54Z

The full duplex playback and recording on Pisound works with pulls/5757.

nodemand · 2023-11-28T14:14:32Z

@pelwell I'm getting the following error in the output when executing sudo rpi-update pulls/5757:

pelwell · 2023-11-28T14:31:13Z

Give it a while - 20 minutes, say - I pushed an update in response to a comment on the previous version of the patch.

nodemand · 2023-11-28T14:32:06Z

okay!

pelwell · 2023-11-28T14:38:20Z

I was too pessimistic - it should be ready now.

nodemand · 2023-11-28T14:49:18Z

Well, I'm not getting any errors, but where there was sound before when starting aplay test.wav -f S16_LE -r48000 -c2 -D plughw:Zero,0 there is nothing now....no sound.

EDIT: Then I played back the file test.wav, that was recorded with arecord -f S16_LE -r48000 -c2 -D plughw:Zero,0 -F0 --period-size=256 -B0 --buffer-size=4096 test.wav on my Mac, but there is only silence...

pelwell · 2023-11-28T15:00:45Z

Is that because you've overwritten your test.wav with silence recorded by arecord?

nodemand · 2023-11-28T15:01:56Z

Yes, I have overwritten it. And I checked. There is sound coming out of the audio source I used as input for arecord.... So why is there silence?

pelwell · 2023-11-28T15:02:21Z

Did you try playing another file? Have you used the same soundcard and configuration on an older Pi and had valid recordings?

nodemand · 2023-11-28T15:06:09Z

I just tried another wav and it won't play back with aplay and mplayer says: Audio device got stuck!
And no, I don't have an older working config and neither do I have a decent older Pi; only a Model B+ ;-). But I will try and re-install Raspberry OS now...

pelwell · 2023-11-28T15:16:00Z

Is this new behaviour? Has playback ever worked before? sudo rpi-update will revert to a kernel without the trial patch.

nodemand · 2023-11-28T15:17:50Z

Yes it is. It worked right before the patch, just not recording and playback simultaneously...

pelwell · 2023-11-28T15:49:46Z

Which Codec Zero alsactl configuration file are you using, the one that used to give you good recordings?

nodemand · 2023-11-28T15:52:07Z

hahaha, yes that is exactly the thing I did not run because it generates an error with me and I thought it did not work because of that so I did not run it anymore...

nodemand · 2023-11-28T15:52:26Z

it works now! Sorry my bad...

pelwell · 2023-11-28T15:59:05Z

Excellent. I'm merging the patch, and it will appear in future releases.

Thanks for the clear and accurate report.

nodemand · 2023-11-28T16:01:21Z

Only one more thing. I cannot run my application because it depends on libasound2 and libasound-dev and portaudio19-dev. And I'm trying to install libasound-dev, but it tells me:

sudo apt-get install libasound-dev

This used to work. Is this as a result of the patch? Not sure what to do now...

pelwell · 2023-11-28T16:07:41Z

No, it really can't be, therefore this is not the place for your question.

Are you sure that libasound2-dev doesn't work?

okay, I really thought I had updated everything. I had not. It must be time to stop now... Thank you sooo much!
