Ok, well doing some research (not fully tested yet- debating about doing this on my main machine or not) but here's a link to get sound working in Win 2000 and XP for some older DOS games. http://www.3drealms.com/tech/vdmsound.html
Looks like it'll work for any DOS game that you might want to try. Here's a tidbit about 3D Realms DOSbox that might also work with other games (again, have to test these things)

"DOSBox - Program which allows Windows 2000 & Windows XP to run our older titles which normally have problems on those operating systems.
ap92vid.zip - 1992 Interview with Scott Miller & George Broussard from NBR Television. (Real Video - 6101k)
dmbelltoll.zip - Unreal User level by Keith Schuler for Planet Unreal Level Design Contest (352k)
waveptch.zip - Sound patch needed for some older Creative Labs sound cards for games that use General MIDI. (9k)
Older Downloads (which have been somewhat supplanted by DOSBox)

moslo15.exe - Mo'Slo v1.5 (DOS) - Needed to help slow down your computer for some of our really old games.  Also useful if you are having problems with our old install program. (25k)
cpukil205.zip - CPU Kill v2.05 (Windows) - Needed to help slow down your computer for some of our really old games.  Also useful if you are having problems with our old install program. (605k)"

Or the link if that helps.  http://www.3drealms.com/downloads.html
