To install pulseaudio was the best thing I did since I enabled vdpau suport.
It is running great to my needs: I'm now able to use my bluetooth headset, my webcam mic, and the system is perfectly integrated. When I anwser a skype call, the amarok player pauses itself untill the call finish. Just skype can't use the headset, but I'll work on it later. Thank u. -- João de Matos Linux User #461527
