Hi Robert. Sorry that your sound has gone into the bit bucket.

Have you still got an earlier kernel you can boot with, and see if the result 
is the same? IIRC there were kernel version/s that had a problem with the 
alsa driver.

Open alsamixer on the CLI, and check that nothing is muted, and sliders are 
up.

Which Fedora version are you using? If it's F8, I might suspect pulseaudio, 
but if sound was working before, maybe not.

Can you download, and run the script below, and post back the link to pastebin 
that is created. This gives a lot of info about your sound setup. (make sure 
to make it executable)
http://bulletproof.servebeer.com/alsa/scripts/alsa-info.sh

Did you have to set any model options for snd-hda-intel in /etc/modprobe.conf?

Just a few things to keep your mind occupied.

Nigel.
