Are you playing from orig disk?

The 1.01 patch fixes this - but then of course there isn't a 1.01 crack yet. so you need the disk & I think its not possible to do a "pure" 1:1 (if you have a working copy - it's not a 1:1)

It's mainly a problem on older SB Live 5.1's or cards using EAX1 or 2, which is what your's sounds like. So if you can't fix it with a sound card driver as suggested by other posters the only other way I have found to fix this is to disable EAX in the game.

You can do this in the sound menu or put "EAXdisabled 1" in your hitman2.ini file

You lose a little atmosphere but it still sounds great without EAX.

hope this helps - non-fiction
