Hmmm, symtoms point to a sound issue.
However, to start with I've learned through experience that the later detonator drivers are not really designed with the TNT chipset in mind. Sure they work, but not as well as some of the older dets.
I run TNT2's at work, and we've gone to the Det. 7.58's I believe for Win2k. Go to
http://dangerousdog.com/downloads/dets/index.htm and you can get all the different versions. Try the 7.58's and see if that solves the problem. If it doesn't look at updating your sound drivers, or check for any IRQ sharing, especially between your video and sound cards.
