[Pkg-utopia-maintainers] Bug#1032880: pipewire: mic input broken by recent changes

[Ralf Jung]

Package: pipewire
Version: 1.2.7-1+b1
Followup-For: Bug #1032880

Dear Maintainer,

I think I am running into the same issue: the internal microphone of my ThinkPad
P15v Gen 3 does not work any more. I am fairly sure it used to work at some
point, but I cannot say exactly when that was. I tried downgrading my kernel,
which did not help. As others found above, I noticed that switching the profile
in pavucontrol to "Pro Audio" provides a working microphone. I have no idea what
else this option does, I am not an audio pro. ;) But I assume the basic mic
should work with the default settings, so I am treating this as a bug.

The microphone is shown as "unplugged", which is odd because yes there is no
microphone plugged in, but also the laptop has an internal microphone and that
one cannot even be unplugged.

I do have firmware-sof-signed installed (which I am mentioning because some
other online discussion I found made it sound like that could be relevant).

In the buggy state, "pactl list cards" outputs:
