Update :

I've just tested the kernel 5.10.4 from ELRepo.
Unfortunately nothing changed - still no sound.
Ah, sad.  Can you run 'git bisect' between 5.9 and 5.10 to determine the
commit that caused the problem?

The problem is that one driver was replaced with another driver. git
bisect wont really help to narrow down why the new driver does not work.

Christian can you run the alsa-info.sh[1] script on your system and send
back the result?

You say sound is not working, can you clarify that a bit? Is no sound
card registered? Is it registered but output stays silent?

Hi,

from reading provided files it seems that you use snd_intel_hda driver, it should be possible to git bisect it between 5.9 and 5.10 as it wasn't replaced.

Catpt driver is used on machines using DSP.
