Default Problem Streaming music in bluetooth headphones

I do not know if it's a bug, but since beta 5 of pecan cm 11 can not play music in my headphones through bluetooth (all functions seem to work good, including file transfer).
My phone normally connects to the car but I can only run a maximum of two tracks .. immediately after the player gets to spend the songs quickly or have FC..
I know the problem is not in the headphones because I connect any other device normally it..
Have formatted the system and tried to clean install but it still fails.
Do not know if it's just me, but I have this problem since beta 5 if I'm not mistaken..
