[pulseaudio-discuss] A2DP - Bluetooth source to alsa sink audio routing

[Cristina Cristea]

Already have it. That and this patch: 
http://gitorious.org/pulseaudio/mainline/commit/4163b44f1fd39be030dda282417f1aa167e7cb55
Without the second one my PulseAudio would crash when trying to connect 
to my phone with the following error:

E: module-bluetooth-device.c: Assertion '(size_t) decoded == 
a2dp->frame_length' failed at 
../../src/modules/bluetooth/module-bluetooth-device.c:1467, function 
a2dp_process_push(). Aborting.
I attached a more complete log.

Thanks,
Cristina
