Sound problems in cities

So, the wierdest thing has happened the last 2 days every time I enter Org on my 5-box shammies. My sound card just goes crazy and starts playing wierd sounds. I mean, these arent even WoW noises, and they seem more like things from my Battlefield 2142. Really guys, it sounds like the opening sequence of a D-day movie.

I'm using a SB X-Fi Fatality. Im using maximizer with 5 screens/accounts on one computer (which might be the problem) and Keyclone. Is there a way to turn the sound off on my slaves that lets it come on when it moves to my main screen?

Thanks guys
