[Q] bluetooth sound not sync with picture topic

Step to reproduce the problem

1. Stop a film with power button to turn off the screen
2. Reopen the app
3. The sound is not in sync with picture

It happens only with bluetooth headset. Sometimes, fast backward or fast forward can make the sync problem too.

Work around : switch to hw codex for a moment (so no sound) then switch back to hw+.
Bluetooth headset : sony SBH20BLACK

Thanks
