I'm noticing a problem with Bluetooth playback. Galaxy s3 running CyanogenMod 10.1 nightlies. My Bluetooth seems to crash during playback, usually when the third or fourth song begins. When it happens, the scrubber in DSub doesn't move, but the action button will reflect whether it would be playing or paused when pressed. After this happens, If I attempt to play music from a different program through Bluetooth, it does the same thing. If I attempt to turn off Bluetooth, the Bluetooth settings menu freezes at "turning off Bluetooth" and a reboot is necessary to turn it back on.
Other music programs do not incite this series of events. I will I include a logcat if you wish, though my untrained eye couldn't pick out any relevant information last time it happened.
