Today I tried to pair my Raspberry Pi 3 with my Jolla smartphone (running SailfishOS). As soon as the devices are connected SailfishOS routes all audio to the RPi but LibreELEC just seems to route it to trash. So the result is a completely muted phone and the only way to get audio back is to close the bluetooth connection.
Now I wonder why does LibreELEC advertise A2DP when it doesn't work? Or is this maybe just related to the RPi 3 and if so: Anything I could test?
