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 https://gitlab.freedesktop.org/pipewire/wireplumber/-/commit/da831fdc65babbc41140cf5ccd85237b9a801b83 See also this bug report: https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/5053 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 SOFTWARE/OS VERSIONS Linux version: 6.18.5 KDE Plasma Version: 6.5.5 and also development versions KDE Frameworks Version: 6.23.0 Qt Version: 6.10.1 Wireplumber version: 0.5.13 Pipewire version: 1.5.84 ADDITIONAL INFORMATION
