[Pkg-alsa-devel] Bug#1092257: alsa-ucm-conf: internal microphone unavailable after upgrading to 1.2.13-1

Package: alsa-ucm-conf
Version: 1.2.12-1
Severity: important

Dear Maintainer,

After a recent reboot, pipewire no longer showed my internal laptop
microphone as available.  The set of pipewire/pulseaudio profiles were
also different.  The internal mic was effectively unusable (except in
the Pro Audio profile, interestingly).

Reverting to an earlier kernel and pipewire packages (known to be
working) didn't help.  This morning, I ran across the following post
which decribes the exact problem I was having (my laptop is a
Thinkpad T16 with MTL Audio HW):

  https://bbs.archlinux.org/viewtopic.php?id=301300

The posts there point to an upstream bug:

  https://github.com/alsa-project/alsa-ucm-conf/issues/472

I didn't see a newer version of 1.2.13 (e.g., a -2) in Debian, so I
reverted to 1.2.12-1 and everything starting working again.

Thanks,

Michael
