I have OSMC installed on a Raspberry Pi 2 and configured to act as an A2DP sink for streaming audio from my smartphone. After installing the December update, this stopped working. I tried re-pairing the phone, but this made no difference.
After some investigation, I was able to find the problem and get audio working again and I was encouraged to share the solution here.
/etc/bluetooth/audio.conf and replaced it with the following contents:
[General] Enable=Gateway,Source Master=true Disable=Socket AutoConnect=true [Headset] HFP=true
After rebooting and re-pairing the device another time, things were working again.
