On a fresh boot
- bluetooth device connects, with sound enabled (I configured bluetooth to default to bluetooth sound device on connect)
- video playback does not stop
- Sound is played perfectly fine.
After a suspend to ram and suspend
- bluetooth connects, but sound is not enabled
- video playback stops
- Workaround: I have to switch from A2DP to HSP/HFP and back to A2DP.
- After applying the workaround (manually, every time), video playback continues, sound plays fine via BT.
I've just updated to HWE kernel 4.8.0-36-generic. But that did not change anything, compared to 4.4 kernel.
To sum up: It's related to suspend/resume, at least sometimes. And Kernel 4.8 does not fix it.
Tracked it further down (ubuntu 16.04).
