Sound is really low after installing openSUSE 11.1

When i installed opensusen 11.1 my sound works but it is really really low. like i can barely hear it. it was loud and ok when i had windows vista. if someone could help that would be great.

Try going to YaST > Hardware > Sound > Other > Volume and move the “Master”, “PCM” and “Speaker” (if there is a speaker) up to 95%. Then close YaST. Then go to your mixer (kmix if KDE, alsamixer/amixer if gnome) and move “Master”, “PCM” and “Speaker” (if there is a speaker) up to a high volume setting. Test. Also check your surround sound volume settings if/where applicable.
