Bluetooth A2DP audio stops after reconnecting headset

[Dan Dascalescu]

Ubuntu 16.04.1 64-bit. DELL E7450 laptop, connected to an LG HBS900 headset.

1. Pair the headset
2. All Settings -> Sound, set the mode to High Fidelity Playback (A2DP Sink) (otherwise the sound is horrible)
3. Test, ensure "Front Left" and "Front Right" sound as they should.
4. Disconnect the headset via the Bluetooth indicator in the system tray.
5. Connect the headset to another device and play audio through it (I took a call).
6. Connect back the headset to the laptop.
7. Attempt to play audio, say in SMPlayer.

No audio comes through. SMPlayer doesn't advance the seek button.

8. Run `pulseaudio --kill`.
9. Reconnect the headset a bunch of times.
10. In Settings -> Sound, try to set the mode to High Fidelity. Only the Headset mode worked, with mono sound. When I'd change the value to High Fidelity, the active sound device moved to the internal sound card.

After a couple more reconnections, I could finally get A2DP sound again.

However, the sound SKIPS randomly a couple times a minute (bug 405294). Playing the exact same MP3 with the exact same player (SMPlayer) on Kubuntu 16.04.1 doesn't reproduce this problem, despite presumably using the same Bluetooth stack.

Super frustrating.

This is possibly the same as bug: 1608820. Could you try the PPA linked to in that bug report and see if it helps you?
