I looked and I only have one option so I don't think it is only related to sound options. I am running a Dell XPS core i7 with 6 GB RAM, NVIDIA GT 435 2GB on Windows 7 64bit. I've tried all of the suggestions in the various threads with no luck. I'm really disappointed that I can't run ArmA Gold (which I just bought from Amazon). Any other suggestions would be greatly appreciated.
Personally, I think BIS should step up and provide a little more assistance since we are still paying for their product
