I recently tried using my old Ubuntu laptop (2012 13" MacBook Pro) to watch a movie. I connected to a Bose SoundLink Mini II, but I started experiencing audio quality issues. Approximately once every couple of minutes the audio would either drop completely or sound convoluted for about 1-2 seconds. The symptoms were identical on both Impish (21.10) and Jammy (22.04).
In an online forum, I found a comment that suggested that switching from the default PipeWire session manager (pipewire-media-session) to WirePlumber resolved a similar issue for someone else. Being unfamiliar with either of these applications I did some reading, and decided to give it a try.
Once I installed
libspa-0.2-bluetooth and enabled wireplumber, my sound audio issues disappeared!
The required commands were:
apt install wireplumber libspa-0.2-bluetooth systemctl --user --now disable pipewire-media-session systemctl --user --now enable wireplumber
It appears that multiple different Linux distros have taken the stance that “WirePlumber will probably replace pipewire-media-session, someday”. For me, that “someday” is today.
If this helps you to resolve your own audio issues on Ubuntu, please leave a comment with your experience and any additional technical details you can share that might help others!
 Jammy is unreleased at the time of writing.
 Upstream PipeWire currently recommends WirePlumber over pipewire-media-session.
libspa-0.2-bluetooth is considered experimental according to the package description.
 It wasn’t immediately obvious to me that
libspa-0.2-bluetooth was required with wireplumber. The above commands aren’t exactly what I did while troubleshooting, but I think it accurately describes the required commands to reproduce my “fix”.
