sound problem in opensuse 11.2 for intel ich9

in my case, the problem is there is no sound..

and fortunately, the solution was simple.. i just run the following command as root:
cp /etc/modprobe.d/50-sound.conf /etc/modprobe.d/sound.conf

btw, prior to executing the command, there was no /etc/modprobe.d/sound.conf file..

also, i still can not get sound from the earphones at the front side of the tower, i use the one at the back..
