You more than likely need ti install a newer version of alsa. Please run
this script and post the link it creates.
If the report shows a version of alsa older than 1.0.14rc3 or 1.0.14rc4, then please download and build from my rpm build environment
here. Just untar it, make and run audio_install as root. It will build rpm packages for your environment (if you have the proper build packages installed).
