sound not quite right

Suse 7.3 pro. I have a dell optiplex gx400 with a built in sound card. It detected my sound card and indeed plays.. however the sound is off. It sounds like a 33 rpm record played at 78. ((Boy I just realized how much I dated myself). The autodetection says I have a 82820 Camino 2 chipset with the AC 97 audio controller. When I play a cd, the sound is right. It just happens off when it is a mp3 or wav. or mpeg. Thanks for the help. -- Dr. Roy F. Cabaniss Associate Professor of Business University of Arkansas Monticello http://cabanisspc.uamont.edu/~rcaban
