Oh, ok, that really is SB compatible. (I used to have an ESS1869
card). When I read the sound-howto I learned that most

With my sound card I originally had the wrong DMA channel configured.
When I played a sound (with, eg, xmms) it was horrible. It sounded
like a record player that was jerking forwards and backwards (the same
portion of the stream would be played in slow-speed several times
before it got to the next portion). Also, when I tried to "stop" in
xmms it would take several seconds for the noise to actually stop.
One time I decided it was time to solve this problem so I booted
windows and recorded every single option and setting in its config.
Then I went back to linux and found that I was using the wrong DMA
channel. I corrected it and the sound was beautiful after that.
That's about the extent of my sound card experience, but make sure you
aren't using an already used DMA channel and IRQ.
