Set up Bluetooth audio streaming via A2DP as per the instructions at the top of this topic. Everything worked really well except for being unable to adjust the output volume at all either through my tablet or through OSMC itself.
I have OSMC installed on a rasberry pi 2 connected to my TV through HDMI. I switched my tv from the HDMI input source to just watch some regular TV for an hour or so. When I came back to OSMC I couldn’t get any audio output at all, Bluetooth or even GUI sounds. Tried rebooting, that didn’t help. So very confused I shut down the Pi and went to bed.
Woke up this morning and booted the Pi up. Sound was kinda working, but it was very distorted. So went searching through settings. Found the PulseAudio service under MyOSMC/Services and on a hunch tried disabling the service. Now audio works as per normal. Haven’t tried re-enabling the PulseAudio service as i’m kinda scared to.
It seems to me as though the PulseAudio service became corrupted or stopped working correctly. But to be honest I know very little about the subject…
