[Bug 1581241] [NEW] bluetooth headset doesn't automatically configure for a2dp correctly (regression)

[Ethan Blanton]

Public bug reported:

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.
