[Pkg-utopia-maintainers] Bug#998221: wireplumber: Headset not working after upgrade

[Luc Maisonobe]

Package: wireplumber
Version: 0.4.4-1
Severity: normal

Dear Maintainer,

Since upgrade to piupewire 0.3.39-3 and wireplumber 0.4.4-1, my Sony WH-1000XM4
doesn't work anymore. It worked flawlessly a few days ago.

After an initial problem with libspa-0.2-bluetooth not installed was solved,
the headset did connect and stay connected, but no sound was produced.

The sound parameters in gnome showed the device in the list for output devices
and the test button.
When pressing this test button, the popup window only showed a single button
"Mono" for the test and not the regular "Left" and "Right" buttons I was used
to. Pressing the button did not produce any sound.

The popup windo also showed a new to me configuration list with three possible
selections:
  - Headset Head Unit (HSP/HFP)
  - Headset Head Unit (HSP/HFP, codec CVSD)
  - Headset Head Unit (HSP/HFP, codec mSBC)

All thee selections show the same behaviour : one "Mono" button for test and no
sound at all.

Looking at journalctl, I get the no messages with Headset Head Unit (HSP/HFP)
or
Headset Head Unit (HSP/HFP, codec CVSD) configurations. However, when using
Headset Head Unit (HSP/HFP, codec mSBC) configuration, I get tons of messages
from wireplumber:
  sco-sink: mSBC buffer overrun, dropping data
