mic issues after upgrade to Debian 11

[L Dimov]

My mic used to work fine under Debian 9 and 10, but after upgrading to 11, people tell me that the audio coming out of my mic is really scratchy and bad to the point where if I do a video call, I'd have to use the phone for the audio part. Not sure where to even start with this... Is there an easy way (is it possible) to revert to the previous driver, somehow, the one that was there in Debian 10?

Thank you in advance for any suggestions.

To help us find the cause of your problem, it would be nice if you
could provide us more information:
- your sound setup (do you use alsa, pulseaudio, jack...)
- which mic device/driver is in question (mic connected to your sound
card which is X, mic from your webcam which is Y...)
- what program do you use for communication (Zoom, Teams, Meet, Skype,
Telegram...)

> It is the built-in mic that is now problematic, with anything I try, including with a variety of various sound recorders in GNOME. I just tried a plug-in mic, and that one works, so I will be using it from now on for meetings, but it is rather unfortunate that I can no longer use the built-in mic in Debian 11, as that same mic worked fine with the previous two stable versions of Debian.

What's the output of 'cat /proc/asound/cards'?
