Hello,
I have been trying my luck with bluez5.21 (built from source) and
pulseaudio (built from pulseaudio/vudentzs-mainline:hfp-ofono-5.0). My
intention is to get my Ubuntu 14.10 installation to be a handsfree unit.
But, I had trouble getting HFP and A2DP to work.
bluetoothctl shows that the 'Audio Source' and 'Audio Sink' profiles are
registered:

The debug log of pulseaudio had a bunch of messages similar to this :
D: [alsa-sink-CX20590 Analog] module-loopback.c: Requesting rewind due to
end of underrun.
D: [alsa-sink-CX20590 Analog] alsa-sink.c: Requested to rewind 65536 bytes.
D: [alsa-sink-CX20590 Analog] alsa-sink.c: Limited to 46336 bytes.
D: [alsa-sink-CX20590 Analog] alsa-sink.c: before: 5792
D: [alsa-sink-CX20590 Analog] alsa-sink.c: after: 0
I: [alsa-sink-CX20590 Analog] alsa-sink.c: Tried rewind, but was apparently
not possible.
Here's the complete debug log (when I tried to switch the audio sink on my
phone to bluetooth):

There were similar messages when I try to make a call using the test
scripts in ofono.
I'm not sure if it's relevant but - I had to uncomment few lines in
default.pa to load the alsa-sink and alsa-source (instead of relying on the
auto detect) modules to get audio to work on my ubuntu installation with
pulseaudio running. Otherwise, the null-sink was being picked up instead of
alsa-sink.
Any thoughts on why this is happening ?
Thanks,
Prathyush
