Better Bluetooth A2DP support on Linux

[Felipe Sateler]

Hi,

Sorry for the late reply. I started writing and then dropped the ball.

It is a very good argument. As a matter of fact, I cannot use my own
bluetooth headset because it is not supported by pulseaudio in HFP mode.
But I cannot commit to maintaining a forked pulseaudio. I simply don't have
time.

I'm sorry, but I'm very time-starved. I cannot push for anything. I'm at
this point a passive follower. If such a fork materializes, I can take a
look. But so far I have not even been able to try out pulseaudio with your
patches! I simply cannot be part of a group taking the lead.

BTW, have other distributions showed interest? Perhaps such a
forked-pulseaudio already materialized by now?
