Although not optimal, you may have to disable the onboard sound and
install an inexpensive sound card.  I have found this necessary at times
when I could not get the onboard chipset to work correctly.

Also, you might play with the order drivers are loaded. Sometimes that
can make all the difference in the world on the output.

I also would strongly recommend you update to the 2.6.6-1.435.2.3 kernel
and other packages as well before you do anything else.  If you have not
updated packages since the install of FC2 there are a lot of packages
that have been  updated, including the kernel (twice) and most of the
alsa packages.
