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.

That's a little concise for any assistance. :-)
Suppose you went to get your car worked on. The mechanic asked you
what was wrong and you said it is not working. That tells him
something so general that there is no way he can fix your car.
At least he has the car, so he can test it himself to see what is
wrong. We don't have your computer. All we have is what you tell us.
Try aplay -lL in a terminal or console and see if your sound card
is found.
If it is,
type alsamixer in a terminal or console and make sure that the
sound has been turned up. Alsa defaults to silence on start to
protect your equipment and your ears. You should be able to do this
from a menu in your desktop as well.
try aplay -v -Dplughw some.wav and see if any sound occurs.
Go to this link,
http://www.alsa-project.org/alsa-info.sh
and download and run the script there. It will scan your machine and
put the output on a website. It will give you a link that you can
post back to the list so we can see the sound setup for your machine.
