I'm sadly having what seems to be a regression possibly related to Plasma 5 to
6. Now often when wine or proton applications initialize audio , e.g. when I
startup EA App inside Steam at launch, or something like REAPER's windows
version ( https://reaper.fm/ the trial is free and unrestricted) at any time I
press "play", the following happens:

1. Audio drops out completely for a split second.

2. A visible notification is shown like my bluetooth device just freshly
connected

3. Audio profile is degraded to something horrible, it sounds like the worst
quality headset telephony codec.

4. Sometimes a second later it resets back to what bluetooth profile I had
before, usually high-quality playback only "AAC". But sometimes it also just
doesn't. This can be checked in plasma's audio device panel, where it will show
the telephony codec "Headset Unit ... mSBC" profile in case it didn't reset
properly.

This also happens when another application is already playing audio in
parallel, which sadly makes this disruptive.
