You might need to check your KMix or the similar thing in GNOME to make sure your "Front Speaker" is not mute.

If it doesn't help and you might need to edit "/etc/modprobe.conf" file as root.
Modify the line from "options snd-hda-intel index=0" to "options snd-hda-intel index=0 model=acer", refer to "/usr/share/doc/kernel-doc-2.6.24/Documentation/sound/alsa/ALSA-Configuration.txt" for details.

Reboot and try.

So, do you hear something from your speaker? Don't test it via system-config-soundcard, it never works.

Well, I forget the default installation won't include kernel-doc.

You can get that reference via:
yum install kernel-doc

Then try to read documents again. You don't need to modify that document, it's just a reference telling the available options of "model=".

That's might be a bug, which was probably fixed on
Mar 28 alsa-plugins-pulseaudio - 1.0.15-3.fc8.1

You could perform an update to get that :
yum update
