[BUG] No audio with 1.5.1 and kernel 5.7.9-1

[Enerccio]

After updating to a new kernel, sof audio no longer outputs anything. I think I managed to get my output from my thunderbolt 3 dock with jack working, but without dock no audio from speakers or built in jack.

can you share the result of alsa-info?

Nothing really suspicious @Enerccio
Can you try speaker-test -Dhw:0,0 -c2 -r48000 and see if the streaming progresses? if it does then it's a codec configuration issue, maybe a wrong set of mixer settings or the codec pins themselves not well configured.

I am assuming you can hear audio playing when you use blacklist snd-sof-pci and force the snd-hda-intel driver to be used with a kernel parameter.

[Enerccio]

No sound input from speaker-test.

I tried older kernel, 1.4.1 sof, forcing snd-hda-intel, no sound. I had big update this morning so something might have fucked it up.

[Enerccio]

However, this is not a hardware problem. If I disable all drivers and boot to qemu running windows, sound is working 100%

https://pastebin.com/FGae8gPz this is what I upgraded this morning

[plbossart]

Alsa-lib and alsa-ucm-conf could be the problem, but that wouldn't explain why you can't hear anything with the legacy snd-hda-intel driver. You really need to get to a point where the legacy audio driver plays audible audio, at which point we can look into SOF-related issues.

[Enerccio]

I set it up with https://wiki.archlinux.org/index.php/Lenovo_Yoga_c940#Linux_5.5_and_later so I am not sure if legacy audio driver should even work after 5.5 though

When I block sof and unblock other drivers, I get only dummy output

[Enerccio]

When I boot with legacy intel drivers:

Ok you were right, it was alsa,

warning: downgrading package alsa-lib (1.2.3.2-1 => 1.2.2-1)
warning: downgrading package lib32-alsa-lib (1.2.3.2-1 => 1.2.2-1)

warning: downgrading package alsa-ucm-conf (1.2.3-2 => 1.2.2-1)

and I have sound back. Why would alsa cause this though?

[plbossart]

@perexg can you help here? which versions of alsa-lib and friends are currently recommended, or are you aware of potential issues with 1.2.3.2? I know there's been a lot of changes recently but haven't tracked version numbers. Thanks for your help!

[perexg]

Please, show the pulseaudio debug log for the latest alsa packages.

@Enerccio any update?

No update for a month and missing input, so closing. Reporter, please reopen if this issue is still valid.
