Hi;

Can someone assist me with the interpretation of the provided data
and how to proceed with getting pulseaudio working?

Thanks,

Default pulseaudio: no sound, Fedora 12, what debugging/diagnostic info is needed to solve this problem?

Hi Rick;

I simply had pulseaudio on mute :-)

Of course I found that out by using pavucontrol from the command
line as that is not in my menu.

Thanks for the help!
