microphone does not work after suspend mode – depending on kernel version

[midrow]

Since the kernel versions 6.8 I have the problem that after suspend mode the microphone does not work, pavucontrol settings change on their own and sometimes wireplumber uses up to 100% of one CPU core. Before the first suspend everything works fine, and the output devices also work afterwards.

The system is up to date, but I stick to the kernel 6.7.10-1-siduction-amd64. In the last months I've searched the internet for hours for ALSA, pipewire, wireplumber etc. but no trail led to a solution.

What has changed since kernel 6.8 (a module) that my machine can't handle it.
