Anytime I start a mission, the first thing I hear is a terribly loud "rumbling" sound. I originally thought it might be my engines, but the rumbling continues even if the engines are at max throttle, min throttle, or even shut off completely. I have tried updating my sound drivers, uninstalling and reinstalling them, and turning off the "engine" sound in the lomac option menu. The issue is also independent of any one aircraft, I hear the noise regardless of the view I'm in, or what object I'm viewing. I know the sound is a bug, because it has only started within the past few days. I believe it's related to my recent upgrade to Vista. Thanks in advance for any help or consideration.
