Comment # 10 on bug 1207129 from Alexander Osthof

I've tested with your packages and got mixed results. Sometimes I was able to
record with 'arecord' after stopping wireplumber, sometimes I even had to
restart pipewire for a successful recording, sometimes nothing worked. I could
really find a pattern to reproduce though.

In any case, when trying the headset in conferences (Jitsi, Slack, Teams) it
performed poorly - either the volume was low, the volume jog was more or less
in binary mode (vol+ = max, vol- = mute). So, I cannot rely on this headset
(yet) for conferences. After nearly a day of trying various combinations of
settings I gave up.

My colleague who's running Gnome on Leap 15.3 (IIRC) had no issues at all with
my headset - plugged in, detected, both speakers and mic worked without issues.
So it seems there are some parts in KDE (which I'm running on top of Leap 15.4)
which make things worse.

I'll pause testing/debugging now but I'll try once more when Leap 15.5 is
available. In any case, thanks for looking into this issue Takashi, very much
appreciated!
