I have the latest rSAP 3.0.5 version under suspect to cause some issues streaming music via a2dp to BT speakers / headset?!
I'm running my Note 3 (SM-N9005) with LineageOS 7.1.2 for a few month, now.
But since a few weeks I seem to have the issue that I can't pause / skip / ff / start the playback with my BT devices after I activated the rSAP driver.
The commands reaches the phone as the menu and back button area on the phone flashed up for a few seconds, while pressing the knob on the e.g. headset, but has no action.
Due to my limited testing so far disabling the driver once activated doesn't help, but I have re-flash the LineageOS image via TWRP.
