Odd thing is, the audio works at initializatoin (the thunderclap) and on the main screen (where you choose zones), but not in any zones (even those with custom audio like MetalGear CTF). I'm temporarily using this ancient 'puter, a Dell Optiplex GXa. It has a Crystal Audio soundchip and, unfortunately, there do not appear to be any drivers for that are more recent than the ones included with Win2000 (believe me, I've looked). My only other game that I have that will run on a system this slow, my old Master of Orion II, has sound that works. DXDIAG reports audio buffering doesn't work, but all the tests work. I tried turning off audio acceleration, but it had no effect.
