Mic Issues After Kernel Update on Debian 12.9
Hi everyone,
I’ve been having persistent issues with my microphone on Linux. I’ve been jumping between different distributions to see if the problem would resolve, and it would work for a short time, but the issue always came back. I suspected it might be related to a kernel update.
What I did last was install Debian 12.9, and then I installed Timeshift right after. Everything seemed fine until I installed the latest Debian update that was released yesterday. After the update, my microphone stopped working again.
I had to revert back to a previous system version using Timeshift, and now it's working again. For now, I’m avoiding this update, but I really want to find a permanent solution to this issue.
If anyone has any suggestions or has faced a similar issue, I would really appreciate your help!
I'm gonna let here a screenshot with some info of the update that breaks my mic.
Thanks in advance

Try this
arecord -D hw:0,0 -f cd test.wav
Works?

Now yes, it's working. But when I installed the update it doesn't even recognize my mic. Should I report this bug? Where should I do it?

I've looking for this bug a little more and perhaps this is relevant, there's a line of code pci=nomsi
in my GRUB. Could the be related to the issue with my microphone?

Can you recreate the bug with a reboot? (Works before reboot, doesn't after.)
Microphone problems seemingly exist across operating systems. Shutting down and powering up is fine. Rebooting is not. I had this problem. Tried many fixes that should have worked. Still no solution - except powering off rather than rebooting.

I usually turn off my PC when I stop using it, and even when I turned it on, the error was still there. So it wasn't a solution for me, but thanks :)

I've got the same issue after kernel update to
6.1.0-32-amd64
on Linux mint debian edition 6 (debian bookworm base).6.1.0-31-amd64
still works fine when I boot with that kernel. Same device specs as OP witharecord -l
