Sound sys does work

I've been looking for a solution to this problem myself. I installed f9
on a new AMD Athlong X2 Dual Core processor with an NVidia audio card
(according to lspci = Audio device: nVidia Corporation MCP61 High
Definition Audio (rev a2)). I could get sound when I booted and when I
logged in, but Firefox and the media players couldn't make a sound. I
found a security option on the "System => Preferences => System =>
Authorisations". There's a set of options for "pulseaudio" that is
disabled. I enabled them all, rebooted the machine, and the sound now
works.
I'm not sure a reboot is required. I know it didn't work right away.
Maybe a logout/login is all that's necessary.
Hope this helps.
