[newbie] Sound Card Problem

[James McDaniel]

I recently installed mandrake 10.0 on a dell dimension 4100.   I replace the crap sound card they packaged with the box with a soundblaster live! mp3 (not the 5.1).   after I installed Mandrake and started KDE the sound card when nuts and then just started make a high pitched squeal.  It never stopped.  I had to turn off the speakers.   help?   j.
