I'm currently having an issue with Mumble. When I open it and connect to a server, my sound intermittently comes on and goes off for mumble. It sometimes goes away when I start the Audio Wizard and cancel out, but most of the time my audio will not properly work. I am currently using Windows 7 64-bit, and a pair of g430 headphones with the surround sound turned off. I have turned off the windows option for giving exclusive access to programs as well but that didn't help.

Any help is appreciated.
