Does anyone know a solution for remapping or reutilizing the Bluetooth AVRCP control buttons for a set of bluetooth headphones (LG Tone HBS-700 specifically) on the LG stock ROM? All I want is for the play/pause, forward/previous track buttons to work on my headphones with the SiriusXM app. I came from CM11 and it worked perfectly there. When SiriusXM was playing, the buttons would affect it, and so forth with other music player apps when they had control. Now that I'm back on trying stock ROM, it of course doesn't work because LG's ROM is a piece of junk. Any recommendations?
