Comment 26 for bug 284994

SOLVED!

At least for my A2DP audio sink (Nokia AD-42W).

1. Set up device in pairing-mode

2. "sudo sdptool browse" and then enter the bluetooth PIN code into the popup window.

OR

"sudo hcitool scan" to get the device id xx:xx:xx:xx:xx:xx
"sudo sdptool search --bdaddr xx:xx:xx:xx:xx:xx y" where y is your service type (in my case y=A2SNK).
Then enter the bluetooth PIN code into the popup window.

Finished.

For A2DP devices (Bluetooth Audio Devices):
Create ~/.asoundrc:
pcm.bluetooth {
 type bluetooth
        device xx:xx:xx:xx:xx:xx
        profile auto
}

If you are getting distorted sound output (e.g. when using a bluetooth mouse) then uncomment last three lines in /etc/bluetooth/audio.conf:
[A2DP]
SBCSources=1
MPEG12Sources=0
