SUMMARY
Ever since Wireplumber updated to 0.5.13 there are problems switching Bluetooth headphones profiles. The problem exists both in Plasma 6.5.5 and also in the builds from 6.6 branch. It can bee seen in both the audio/volume plasmoid/widget and also in audio KCM. Looks like the cause is the change in Wireplumber which on profile change does not change sinks anymore but now changes only ports on the same sink.
The specific wireplumber commit changing this is

STEPS TO REPRODUCE
1. Connect Bluetooth headphones
2. Try changing the profile either with Audio Plasma widget or Audio KCM

OBSERVED RESULT
The new profile you select is not selected when reopening the audio profile menu

EXPECTED RESULT
The profile should properly switch and the GUI should properly indicate the new profile
