Michael, the nearest to that that I have had was with the 56.64 drivers, - but I know they worked fine for you!
As I reported on the 3D driver thread, there were others that got black screens at times with 56.64
Probably no help, - but the effect was similar, ...
Just to make it clear, it's not just that the stereo doesn't work, - even 56.64_winxp2k_english_whql.exe, on it's own, doesn't work when trying to run any of the screensavers, (MA2 MD, 1.1wide, AquaReal, etc!).
..... You did ask!
