[Pkg-utopia-maintainers] Bug#1123875: pipewire: New alsa libs (1.2.15) breaks pipewire (only dummy output and no mic after upgrade)

[Gianpaolo]

Package: pipewire
Version: 1.4.9-1
Severity: important
X-Debbugs-Cc: gianpaoloc at gmail.com

Dear Maintainer,
I had to revert back the following packages:

[DOWNGRADE] alsa-ucm-conf:amd64 1.2.15-1 -> 1.2.14-1
[DOWNGRADE] alsa-utils:amd64 1.2.15-1 -> 1.2.14-1
[DOWNGRADE] libasound2-data:amd64 1.2.15-2 -> 1.2.14-2
[DOWNGRADE] libasound2-plugins:amd64 1.2.12-2+b4 -> 1.2.12-2+b1
[DOWNGRADE] libasound2t64:amd64 1.2.15-2 -> 1.2.14-2
[DOWNGRADE] libatopology2t64:amd64 1.2.15-2 -> 1.2.14-2

to have back my audio sinks and mic. With the new version of the pakages, in fact, pipewire/wireplumber only offers the "Dummy output" and no mic at all. 
At the same time this does not seem to be a pure alsa issue since invoking:

speaker-test -Dplughw:CARD=sofsoundwire,DEV=2 -c 2 -t sine

I hear the expected sound from my speakers, even with the 1.2.15 version of the libraries.

Notice that "aplay -l" and "aplay -L" produce the exact same result with the 1.2.14 and 1.2.15 alsa libraries. 
I am attaching the output of pw-dump command executed with alsa libs 1.2.14 and 1.2.15, in case they could help understanding where the problem stands.

Final note: I have an ArrowLake notebook (Intel(R) Core(TM) Ultra 7 265H - Dell Pro Max 16 Premium MA16250).

Is there anything I can do to help debugging this issue?

Sincerely
  G.
