Ola Salvatore.

As this only happened since F8, I'd suspect Pulseaudio, and I did have 
problems with Pulseaudio with F8 on one machine. No sounds, but as soon as I 
disabled Pulseaudio, the sounds came back. To disable it, simply remove the 
package, alsa-plugins-pulseaudio.
yum remove alsa-plugins-pulseaudio

With the package above still installed, open alsamixer in a terminal as user. 
You will only see one slider, the pulseaudio one. Open alsamixer as below, 
and you will see all controls available for the soundcard.

alsamixer -D hw:0

There may be something that is now muted since F8, and needs to be unmuted 
(the M key toggles the mute/unmute). Left, and right arrow keys for scrolling 
through the controls. Some may need to be pushed up. The usual ones are, 
Master, PCM, Front, CD, if they exist. If a switch (external amplifier, or 
external speaker) exists, try toggling that, while some audio app is playing 
something.

Would you post the output from the following commands please.

cat /proc/asound/cards
grep ^Codec /proc/asound/card?/codec*
/sbin/lsmod | grep snd

All the best.

Nigel.
