[Galaxy S II Android Development] Forsquall:
Same thing happens for me when using a stereo bluetooth speaker.

It works OK after a fresh reboot, but then fails after some uptime. The same i9100 and speaker were OK on CM12.1, while the same speaker is OK with a Nook HD on CM13.

[MENTION=6159291]Lysergic Acid[/MENTION], here's a logcat when it's failing, in case it helps:

In case it helps, here's a logcat from MXPlayer giving a black screen in HW decoder mode. It repeats over and over while playing. This is different from the "runFimc" error that caused the same effect on CM12.1
