Not sure if it's the voice pack that I installed or something that went wrong with the install. After the initial install the audio all around seemed to be pretty good but once I started a Multiplayer Game with the Bots the audio had a lot of static. I decided to try some of the voice packs that I have and after the install it also was a lot of static. I am running this on Windows 7 64bit and the brand is emachines. Not sure if that has anything to do with it either. The other GOG games that I own don't have a problem on this PC also.

Had same issue, tryed to start as admin, works everytime now :)
