Just a quick note on this. I did not have this issue at all under my older system, but after more than a year and attempting to reinstall and run the game on my new system with the new nVidia drivers, I had the same issues that many others have reported. Since I have not found any answers that helped me, I thought I would just post this here. I found the problem on my own system.

I tried the other fixes that worked for other folks, but they did nothing for me. I uninstalled the HD audio drivers that come with the Forceware and viola, the game works like it always did. I use a separate Sound Blaster Live! card for sound.

Just thought I would drop a note. If this has already been mentioned, my apologies!

Kind regards
