Bug#1027483: linux-image-5.10.0-20-amd64: sound with firmware-sof-intel on Intel Lake stops working with newer kernel

[Malvin Gattinger <malvin@w4eg.eu>]

Dear Salvatore,

> https://wiki.debian.org/DebianKernel/GitBisect

Thank you for the quick reply and suggestion to bisect this. But 
(un)fortunately the laptop where the problem occurs is not my own 
and I have neither the experience nor time to compile and try 
kernels on it. Sorry if this would be my job, now that I made a 
report. I only saw those forum posts so far and was mostly hoping 
to get other eyes on this by filing a bug.

Two more things I can add:

- without "firmware-sof-intel" no audio devices at all are shown 
 by pulseaudio.

- with the 6.0 kernel from bullseye-backports there are also no 
 audio devices at all, even when "firmware-sof-intel" is 
 installed.

kind regards,
Malvin
