</div></div>Ive never experience such problem, in any case it does not look like a<br>
Bluetooth problem since you get the transport configured and loopback<br>
is loaded as well, btw are you sure your sink is working<br></blockquote><div><br></div><div>Yes, I think so. I was able to play an mp3 file using mplayer while the pulseaudio instance was still on.

</span>Perhaps it is related to udev rules, iirc Ive replaced mine with the<br>

properly.<br>
