Pulseaudio Volume Control won't open (but sound works fine)

[Amurko]

So sound works fine on my system but I can't adjust any of the settings.

So I try to open the Pulseaudio Volume Control app and an error message pops up:

"Fatal Error: Unable to Connect to Pulseaudio: OK"

I recently reinstalled.. this problem was present before AND after reinstalling. Reinstalling did not help at all.

Running Ubuntu 11.10

Where to I begin the troubleshooting?

Try purging pulse config files.

rm -r ~/.pulse ~/.asound* ~/.pulse-cookie 
sudo rm /etc/asound.conf

Reboot
Ignore any 'No such file or directory' errors
No joy? Use the alsa-info-script to provide detailed information.
Run this command in a terminal:

wget http://www.alsa-project.org/alsa-info.sh -O alsa-info.sh && bash alsa-info.sh

Choose the upload option and provide a link for the output.

If you didn't get this working, have you tried

pulseaudio -D

if that works, this should help http://shuffleos.com/3496/how-to-enable-all-applications-in-startup-applications-ubuntu-11-10/
