Bluetooth not working

[mooncosmique]

I have UT on a Nexus 4 and cannot get the bluetooth headset I have to work. Oddly, I was able to listen (but not talk) on Skype but after upgrading software on phone I can't get any audio to work. Both the headset and phone say that it is connected but still no audio. I have unpaired and re-paired and restarted phone but so far no luck. The headset is Plantronics Voyager 5200

Thanks

Same here (Nexus 5) it seems is a pulseaudio issue, can't switch profile to headset_head_unit when trying to use bluetooth headset/car kit microphone

profiles:
		a2dp_sink: High Fidelity Playback (A2DP Sink) (priority 10, available: unknown)
		headset_head_unit: Headset Head Unit (HSP/HFP) (priority 20, available: unknown)
		off: Off (priority 0, available: yes)
	active profile: off

I manage to force it to switch to A2DP but of course no mic

profiles:
		a2dp_sink: High Fidelity Playback (A2DP Sink) (priority 10, available: unknown)
		headset_head_unit: Headset Head Unit (HSP/HFP) (priority 20, available: unknown)
		off: Off (priority 0, available: yes)
	active profile: <a2dp_sink>
