Internal microphone does not work with 5.12 (Tiger Lake, X1 Nano)

[Nico Schottelius]

Hello,

it seems that the internal microphone does not work anymore with
5.12.6/5.12.7. I am somewhat sure it used to work within the 5.11.x
series and that sound did not work at all on 5.10.

I have uploaded the hardware information on

http://alsa-project.org/db/?f=f1a2b32db122695b2cf736db27cb6ed2fa8a9042

The microphone of a plugged in headset however *does* work.

Is this a known bug/regression and is there anything I can do to debug
it?

Best regards,

Nico
