got the same problem. i got a soundblaster live!. so far no one could provide a solution for this. i also had to apply the ATI pak file fix, could that have something to do with it? i also tried various speaker settings from within the game, but no luck. if i set a custom music file to be the soundtrack file, music plays but then it plays all of it. i really like the music and i think it greatly adds to the atmosphere, so i would appreciate any suggestions. i uninstalled all codec packs previously because they used to give me hard time with some games (aoe3) so i don't think they could be the problem.
