Title:
bluetooth headset doesn't automatically configure for a2dp correctly
(regression)
Status in bluez package in Ubuntu:
Confirmed
Bug description:
I have a bluetooth headset capable of several modes of connection
(headset, handsfree, and a2dp). In 15.10, once I had correctly
configured it for a2dp once, applications using pulseaudio could use
it freely each time it was connected to the machine.
In 16.04, upon connection, applications that attempt to use it appear
to hang waiting for something. I have to fiddle with its settings
(and sorry I can't be more specific, but it's not clear to me exactly
what sequence fixes it; I change it to/from headset and A2DP in
blueman a few times, do the same in pavucontrol, etc., and at some
point it starts working) for several minutes to get it working in a2dp
mode. It appears that after connection I can put it in headset mode
and start playing to it immediately, but of course the audio quality
is horrible.
Once I've fiddled it into working, it works until disconnected, and
upon reconnect it behaves the same as before I fiddled it into
submission: a2dp connection, but clients accessing it hang.
