SUMMARY When I plug in the bluetooth headset, or change its profile from headset to audio playback, all sound devices become muted: not system dynamics only, but headset itself too. Also today is muted during Skype call, when plasma taskbar component glitched. STEPS TO REPRODUCE 1. Connect, disconnect or change configuration of bluetooth headset (B703/HN-B701 in my case) OBSERVED RESULT Previous sound device is muted, sound device, connected sound device is not EXPECTED RESULT All sound devices is muted, so user have to enable needed devices manually SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Neon 5.19 User Edition, Plasma 5.19.3 (available in About System) KDE Plasma Version: 5.19.3 KDE Frameworks Version: 5.72.0 Qt Version: 5.14.2
That's strange. If you install and open the 3rd-party PulseAudio Volume Control app, do you see the same behavior in that app?
I installed pavucontrol-qt and turn off plasma management by 'killall plasmashell'. In pavucontrol-qt initial sound state after boot is still muted, but after first connect, headset volume was 100%. I saw this logs in konsole after plasmashell restart: file:///usr/share/plasma/plasmoids/org.kde.plasma.bluetooth/contents/ui/FullRepresentation.qml:121:13: Unable to assign [undefined] to

Thanks for the info. I wonder if Bug 422948 is related in any way.
Is this still a problem?
For now, I can connect my current bluetooth headset without any issue
