How can I get rid of skipping or choppy playback with my Audigy soundcard?

Hello, all, have a question on the brain - one I can't quite solve myself. Under Slackware 11, (and KDE) my Audigy card works fairly well - except for choppy sound. I reduced some of it by reducing the buffer size to 8 ms, but that didn't cut it out completely. If I use a Slax or Knoppix LiveCD or run SuSE 9.1, there is no problem. Video works fine. I've read something about a different module for the Audigy line, not "emu10k1," but don't remember what exactly.

What else do I need to post, and what else can anyone suggest? Thanks for any help, and sorry for any excessive length on the quotes.

Hmm... what about those outputs in Slax? Then we can see what the differences are.

Comin' right up...
