I have isolated a method for making things work, for others who may have similar problems:
1) Connect headset by turning it on. 2) Set headset to headset (not a2dp) mode using blueman-manager 3) Disconnect headset from blueman-manager 4) Reconnect headset from blueman-manager; it will show Audio Profile: off 5) Set audio profile to A2DP At this point, it generally seems to work. Shorter sequences have not yet reliably worked for me. Some parts of the dance can be done in pavucontrol, but it's easiest to do it all in one place. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1581241 Title: bluetooth headset doesn't automatically configure for a2dp correctly (regression) Status in bluez package in Ubuntu: New 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.
