SuSE 9 and sound

HI All, I just reinstalled SuSE 9.0 after I screwed up the video and it started that boot loop again. Anyway, I cannot figure out what program I used to get the sound going. I opened something and mesed with the volume under 3D (it is muted by default) and it worked fine. I opened everything under 'Multimedia' but nothing seems farmiliar. Did I miss something in the install? Which program was it (so I can install it)? Thanks Russ
