Master of Orion 2 (lags then crashes) - there is a patch 1.41 I think should work and try the compatability thing in xp it's realy good or disable sound alltogether
Mechwarrior 2 Mercenaries (installs but does not run at all)
Mechwarrior 3 (wont install due to ?sound compatability?)
it's an issue with all mechwarrior series including Mechwarrior 4 and it's definetly the sound drivers check with their official site it says something about this, but i've solved once with newer sound drivers
Aliens Vs. Predator (installs but fails to play smoothly also sound problems)- you just wrote sound problems, so it's obvious
Descent 3 (does not install) - dunno never played it
Fallout 1&2 (minor graphics and sound problems then crashes) - ditto
Sid Meyer's Alpha Centauri (where to start... everything?)- my favourite...there are two patches get the one for xp on www.dlh.net in the alpha.ini or alphacentauri.ini moddify add the line forceoldvoxelalgorithm=1 it still gives you that error but works or move the file sound.dll and try...but if the last one works ... then you've got some real sound issues ... and no help there ... sry
hope that answers your questions...
any other questions
