[Pkg-utopia-maintainers] Bug#1004016: pipewire 0.3.43 upgrade automatically selects broken profile

[Alexander Clausen]

Package: pipewire
Version: 0.3.43-2
Severity: normal

Dear Maintainer,

After upgrading pipewire (and related pipewire-pulse packages etc.) from
0.3.42-1 to 0.3.43-2, my audio input from my webcam was suddenly not working
anymore (as in: WebRTC-based applications were complaining about not
being able to use microphone input). In `pavucontrol`, under "Input Devices",
it was impossible to set the device as the default input - it always switched back to
"monitor of built-in audio analog stereo" or something like that. After
some trial and error, I found out about the "Pro Audio" profile, and it
turns out, this profile was somehow selected (without user interaction).
Switching my webcam back to "Mono Input" made it possible to use again,
as in before versions.

Reading the pipewire FAQ, it seems the "Pro Audio" profile is not really
meant to be used for devices like webcams:

https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/FAQ#what-is-the-pro-audio-profile

Would it be possible to not switch to it automatically, or only switch
to it for devices that are actually compatible with this profile?

Thanks,
Alexander
