[Bug 2141723] Re: microphone silent with snd_soc_avs

I can reproduce this issue in Kubuntu 25.10 (questing) under Wayland (if
that matters?). The issue started when updating from linux-
image-6.17.0-12-generic to linux-image-6.17.0-14-generic. Under linux-
image-6.17.0-14-generic it goes away when I blacklist the driver
snd_soc_avs.

** Description changed:

Something caused `blacklist snd_soc_avs` to be required on
6.17.0-14-generic. 6.17.0-12-generic was working as it had
`snd_hda_intel`.

2) The version of the package [they] are using

Bad version: 6.17.0-14-generic

3) What you expected to happen

The microphone should always work in Chrome, Firefox, and Brave.

4) What happened instead

> During calls, people cannot hear me. I can hear them perfectly. Sometimes browser shows "Mic not found". Happens with and without headphones. Restarting PipeWire sometimes temporarily fixes it.
> Hardware appears functional. ALSA layer is functional. [comment: probably config not data worked] PipeWire source node exists. Browser does not create capture stream. Restarting services sometimes restores mic temporarily.
