[Pkg-utopia-maintainers] Bug#992839: pipewire: Upgrade replaces PulseAudio with PipeWire, breaking xfce4-pulseaudio-plugin volume control widget.

[Ilan]

Package: pipewire
Version: 0.3.33-1
Severity: important
X-Debbugs-Cc: ilan at decodecode.net

Dear Maintainer,

I just upgraded my Debian Sid/unstable, which *removed* PulseAudio, replaing it with PipeWire, 
and breaking my Xfce panel widget -- volume control xfce4-pulseaudio-plugin.

Audio works, but volume can not be changed, not even with keyboard keys.

I haven't attempted any suggested fixes, yet, because unsure which are 
relevant: pipewire-pulse service? pipewire-audio-client-libraries? pipewire-media-session?

Anyway, this should not have happened! I expect an upgrade to not break my system.

Please advise.
Thanks.
