Thanks, I'll be around today.

Ok. I've done some minor debugging myself, but haven't got much. The 
pulseaudio debug log is here: http://pastebin.se/s3CIWSl0
At the same time I get these messages in syslog: http://pastebin.se/bilI1XGX

It looks like bluetoothd does find the A2DP Sink (and source?!), but 
then there is no callback to PulseAudio to register the transport, 
because this part is only shown for HSP, not for A2DP:

D: [lt-pulseaudio] bluetooth-util.c: dbus: 
interface=org.bluez.MediaEndpoint, path=/MediaEndpoint/HFPAG, 
member=SetConfiguration
D: [lt-pulseaudio] bluetooth-util.c: dbus: 
interface=org.bluez.MediaEndpoint, path=/MediaEndpoint/HFPAG, 
member=SetConfiguration
D: [lt-pulseaudio] bluetooth-util.c: Transport 
/org/bluez/634/hci0/dev_00_18_91_3A_B6_EC/fd3 profile 2 available
