Possible DWC I2S kernel driver issue for RPi 5 #5747

Closed nodemand closed 11 months ago

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:

#include <alsa/asoundlib.h>

#include <stdio.h>
#include <stdlib.h>

}

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 commented 11 months ago

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 commented 11 months ago

Thank you so much!

gtrainavicius commented 11 months ago

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

pelwell commented 11 months ago

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

nodemand commented 11 months ago

okay!

pelwell commented 11 months ago

I was too pessimistic - it should be ready now.

nodemand commented 11 months ago

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 commented 11 months ago

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

nodemand commented 11 months ago

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 commented 11 months ago

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

nodemand commented 11 months ago

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 commented 11 months ago

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

nodemand commented 11 months ago

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

pelwell commented 11 months ago

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

nodemand commented 11 months ago

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 commented 11 months ago

it works now! Sorry my bad...

pelwell commented 11 months ago

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

Thanks for the clear and accurate report.

nodemand commented 11 months ago

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...

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

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