Buzzing Noise

Hi,Wondering if anyone has ever had this problem with a buzzing and sort of static noise in the cockpit view of the default 172 and 182. Only get the sound in this view. I have isolated the problem to the file wind3 in the sound folder. I tried to replace the file from the original cd but problem still exists. I have a creative x-fi sound card and the latest drivers for windows 7. I can mark out the file in the SC but would like to find the problem to fix it.Any help would be appreciated.Thank-You,Ted
