I found the following fix for the high pitched ASUS M2NPV-VN sound
problem.  The fix is described in:
	http://www.planetamd64.com/lofiversion/index.php/t23938.html
	http://quaggaspace.ort/a8nvm/

Essentially, add the following line in /etc/modprobe.conf:
	options snd-hda-intel position_fix=1 model=3stack

Ubuntu distro has /etc/modprobe.d/alsa-base that this options line
goes into, but I couldn't find the file in FC5 so I stuck it in
/etc/modprobe.conf.  If anyone knows of a better place to put this fix
please let me know.
