Did I loose a Kernel driver ?

fresh install of what ? Ubuntu, Suse, Mandriva, Fedora, FreeBSD, Slackware, Other ?

did you try running alsaconf as root from the command line ?

The install is FC 10. I ran the command and it still does not work.
Thanks

did the command run successfully ?
did it show any errors ?
did you check the Audio mixer settings afterwards to ensure the sound wasn't muted ?

you need to give back more than "nope, didn't work" We can't see what is happening on your end..

Sorry about that. I run the alsaconf and the system reports back that it has no cards. No supported PNP or PCI cards found.

Then Probing Legacy ISA cards ... then I see these errors

modinfo: could not find module snd-cs4232
modinfo: could not find module snd-cs4231
modinfo: could not find module snd-es1688
modinfo: could not find module snd-sb8
Then

Probing legacy cards.. This may take a few minutes..
Probing: opl3sa2 : FOUND!!

Then it configure the opl3sa2 ....

The audio for the Dell is Sigmatel9205 , thats what the bios says.
Then this message

Loading driver...
/usr/sbin/alsaconf: line 678: rcalsasound: command not found
Setting default volumes...

Then this
Now ALSA is ready to use.
For adjustment of volumes, use your favorite mixer.

Have a lot of fun!
