My bluetooth headset BM-8810 is connected and usually can be used as a playback device. But sometimes it doesN't work: it can be connected (see 2.png) but cannot be chosen as a playback device in Systemsettings/Multimedia/Sound_and_video_settings/Devices as it is grayed out (see 2.png). As I experience, it happens after suspend and resume my computer. After suspend, turn bluetooth off and on is needed to connect the device but still not connected as an audio device. I am using KDE4.14.9 on OpenSUSE13.2 Reproducible: Always
I'm sorry, but KDE 4 is unmaintained. Also this looks like issue with BlueZ or PulseAudio and not Bluedevil.
