Try this!
1) Pair the headset and run pavucontrol the pulse audio volume control panel.
2) Go to configuration
3) Change to off
4) Change to a2dp
or
pacmd set-card-profile cardnumber off
pacmd set-card-profile cardnumber a2dp
Opening unity-control-center sound will switch it back to hsp
Here is some output from unity-control-center when I open it with the
bluetooth playing and when I try to switch it to a2dp
{code}

Title:
A2DP works randomly

Bug description:
Hello,
There is a problem with the bluetooth mode A2DP. When I connect my
bluetooth headphone, sometimes I can activate the A2DP mode (which
gives a good sound quality) and sometimes I can't (nothing happened
when I change it in the configuration window), and I need to switch to
HFS/HFP (bad sound quality). Note that some logs are attached.
I found on the internet a work around which is to put in
/etc/bluetooth/audio.conf a line
Disable=Socket
It seems to work (well it's hard to say for the moment because I
didn't have the time to do much tests), but I would like to know what
Socket is supposed to do.
Would it be possible to solve this bug when Socket is activated too ?
Thank you,
Tobias.
