Comment 31 for bug 1897965

Yeah the changelog sounds like it's talking about this issue being fixed:

pipewire (0.3.19-3) unstable; urgency=medium

  * Team upload
  * Don't enable audio-related plugins by default.
    Using pipewire for audio is considered experimental for Debian 11,
    and in particular the with-pulseaudio flag file will result in
    PulseAudio and Pipewire fighting over Bluetooth devices.
    - If you're experimenting with pipewire-pulse, please see
      /usr/share/doc/pipewire-audio-client-libraries/README.Debian
      for details of how to re-enable these.

but looking deeper at the debdiff I don't understand how it was done.

Let's assume this is indeed fixed in hirsute...
