This is just a quick post covering a sound problem I encountered when running OpenSuse 10.2 with Nvidia nForce 430 and Asus M2NPV-VM. The solution that worked for me is to open the /etc/modprobe.conf.local file and make sure it includes the ‘options line below
# please add local extensions to this file
options snd-hda-intel position_fix=1 model=3stack
This did the job nicely. I found the solution here, which has a lot more detail.
