[PD] Ubuntu. PD, Pulseaudio problems

[Marco Donnarumma]

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

http://ubuntuforums.org/showthread.php?t=1130384

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..
