Comment 13 for bug 1065380

I've found this (mostly) fixed using the backported pulseaudio ppa from a recent WebUpd8 post about system-wide equalizer support:

Headset connects automagically, however sometimes the volume control isn't connected to the bluetooth sink, but the output always gets sent to the proper sink.
