When using the ATC some of the messages sent or recived are all staticey, so you can not hear what is being said except to read it in the window. I have gone in and changed the sound to the default sound and still the same. I switch it to the Max Sound on board soune card and the same thing happens. Went to the soundmax.com web seight though you have to buy a driver update program to get them, I could not find them on the soundmax seight for down load. If any one can help me on this would be appreciated. The static is quite annowing.
