 I have BlackBerry 9780 and I am connecting it with my ARM based board
 which is having pulseaudio version 0.9.21 and alsa 0.9.21. After having
 successful A2DP  connection between Black Berry and my board sound starts
 coming from the audio jack of board but quality of sound is not very good.
 It has lot of disturbances in it. When I saw logs in /var/log/messages
 than it shows following logs:-

 Oct  1 19:08:35 localhost pulseaudio[657]: alsa-sink.c: ALSA woke us up to
 write new data to the device, but there was actually nothing to write!
 Oct  1 19:08:35 localhost pulseaudio[657]: alsa-sink.c: Most likely this
 is a bug in the ALSA driver '(null)'. Please report this issue to the ALSA
 developers.
 Oct  1 19:08:35 localhost pulseaudio[657]: alsa-sink.c: We were woken up
 with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or
 another value < min_ava.

 All worked fine when I am using my Ubuntu desktop to send audio stream to
 board. This is happening specifically with BlackBerry phone. Please help
 me to fine tune it. My configuration files of pulseaudio are attached.
