Hi David,

If you're already familiar with elrepo then I'd suggest you try their 
updated alsa sound drivers.

yum --enanlerepo=elrepo install kmod-alsa

and reboot.

Also, don't forget to check your sound device isn't muted. The ALSA docs 
state:

Note: All mixer channels are muted by default. You must use a native
       or OSS mixer program to unmute appropriate channels (for example a
       mixer from the alsa-utils package).
