[Elephone P9000 ROMs, Kernels, Recoveries, & Other ] BlackLodge:
I also found the BT bug. I tried with a JBL speaker that I have and same behavior that others descripted: It is able to pair without problems, but later there is no sound. If I disable BT on the phone, everything works fine again.

This speaker worked perfect with CM13.

Here a logcat of the moment I press play, in case it helps [MENTION=6236982]Deepflex[/MENTION] understand what is going on:
