Hrm...I haven't gotten exactly that, but for a while I was getting random static in different games at different times.
I have the SB Live! 24 bit sound card. When I reset the drivers so that EAX was not on by default, the static went away.
Try disabling EAX or whatever enviroment sound settings you may have and see if that helps.
