Yesterday I decided to give RC1 a shot, install went perfect. I had the system completely setup no driver issues until I decided to test the microphone. When I went into the configuration for the microphone and played the device so I could hear it...All I could hear when there was any sort of activation was what almost sounded like a thunderstorm...just huge booms. Whenever I would click or use the mouse while this was active I could hear those as well. When speaking into it I could still faintly hear myself but the thunderstorm noise was so much it just took over. Is anyone else having this issue even without this microphone? Could it be the USB audio driver?
