I have recently upgraded my PC to a 1.3 gig Athlon and added another 160 MB RAM, and now have constant problems with sound on my Game Theater XP. In WinME on the same computer all is fine, but Windows XP and 2K are not so good.
Before when I had 224 RAM the problems were only occasional, and went away as soon as they came. I read elsewhere on NT Compatible that its has to do with where the drivers are loaded. The problems I have certainly tie in with the memory problems. Maybe I'll try taking 128/256 out and see what happens.
