Bug#993389: libcanberra-pulse: Add pipewire-pulse as alternative dependency to pulseaudio

[Patrice Duroux]

Hi,

Some «recent» package update broke libcanberra working nicely with the PipeWire
pulse server.
My system is having the following:

$ dpkg -l | egrep '(pulse|pipewire|canberra)'
ii  gnome-session-canberra                0.30-7+b1                           amd64        GNOME session log in and log out sound events

ii  libpipewire-0.3-modules:amd64         0.3.35-1                            amd64        libraries for the PipeWire multimedia server - modules
ii  libpulse-mainloop-glib0:amd64         15.0+dfsg1-2                        amd64        PulseAudio client libraries (glib support)
ii  libpulse0:amd64                       15.0+dfsg1-2                        amd64        PulseAudio client libraries

ii  libpulsedsp:amd64                     15.0+dfsg1-2                        amd64        PulseAudio OSS pre-load library
ii  pipewire:amd64                        0.3.35-1                            amd64        audio and video processing engine multimedia server
ii  pipewire-bin                          0.3.35-1                            amd64        PipeWire multimedia server - programs

ii  pipewire-pulse                        0.3.35-1                            amd64        PipeWire PulseAudio daemon
ii  pulseaudio                            15.0+dfsg1-2                        amd64        PulseAudio sound server
ii  pulseaudio-module-bluetooth           15.0+dfsg1-2                        amd64        Bluetooth module for PulseAudio sound server
ii  pulseaudio-utils                      15.0+dfsg1-2                        amd64        Command line tools for the PulseAudio sound server

Simply running:

$ /usr/bin/canberra-gtk-play -f /usr/share/sounds/freedesktop/stereo/bell.oga

does not provide me any error nor sound.

Then (force) removing libcanberra-pulse gives me back again the sound output.
Note that I do not know in such case if the sound goes through gstreamer or
alsa. But even removing libcanberra-gstreamer package, I am still getting the
sound.

Moreover:
$ paplay /usr/share/sounds/freedesktop/stereo/bell.oga
is working fine.

Conclusion:

Even if pipewire-pulse provides pulseaudio, not sure that verything will be fine
regarding libcanberra.
Otherwise everything is fine with pipewire-pulse.

Wishes,
Patrice
