Hi,
I've tried it exactly like you described but after a reboot LE shows some error messages at boot time (something about beeing unable to start pulseaudio service) and I am not able to connect my phone via bluetooth anymore.
My default sink is called a little bit different (it's a hdmi output) but other than that my I tried to follow your steps exactly
Got an idea?
I concur with your suggestion: It would be nice to be able to do this via GUI witch would be less prone to human error.
What really baffles me: One would think that playing audio from your mobile device via KODI in e.g. your living room, where a nice sound system is connected, would be a more useful scenario than playing audio from your KODI to a bluetooth speaker.
Yet bluetooth receiving is quite cumbersome to set up and you only see very few a forum posts here and there about it.. Most of them pretty old.
