Public bug reported:
The microphone on my DELL Precision 5690 doesn't work after upgrading to
the Linux image 6.11.0-17 from 6.8.0.52 - Ubuntu 24.04.2 LTS.
When I go to the audio panel, the microphone seems to be receiving a
saturated signal, and it continuously fluctuates (see video). When I
record, I hear a crackling sound.
This is not the first time this issue has occurred; it happens with
every new kernel since at least the kernel 6.8.0.41.
I tried purging and reinstalling PulseAudio, PipeWire, linux-firmware,
and ubuntu-drivers-common, but it didn't solve the problem. I am unable
to install sof-soundwire.
