i had similar problems on Jaunty and i solved everything with this tutorial:


it's pretty complete. On my machine every application uses now Pulseaudio
mixer, except Pd which makes happily use of Jack.
Starting qjackctl from terminal (before using pd) terminate automatically
Pulseaudio - avoiding *snd_pcm_open (output): Device or resource busy*.
Once you close jack Pulseaudio will be initialize again automatically when
another application ask for it.

hope this help..
