[UFO Chicago] static on dsp when screen redraws?

In the reinstall of flynn, I threw in my SBLive! card, and it works
great, except when the screen is active. When I'm playing a
video, or even when mozilla redraws -- like when a new page is loaded
and the whole screen is redrawn -- there is static on the dsp. It
doesn't sound traditionally "choppy", it's sounds more like static. I
should test to see if the static is present even when no sound is
playing... that'd be useful to know.

I wondered if maybe it was an IRQ-sharing issue, but the video card is
on 9 and the sound card is on 10. The cards are also not directly next
to each other, and moving the wires around in back doesn't seem to
make a difference. (Like, moving the speaker wire away from the
monitor cable.)

You guys have any idea what the deal is with this? It's a dual-PII 333
-- it should be capable of playing a 300x400 mpeg without choppy
sound. Or much less, redrawing the screen without distorting oggs.
