When I first started making a video in Movie Maker 2012 on Windows 8, the audio worked just fine in the video. Now every time I open a movie file in Movie Maker the video plays fine, but the audio comes out only as loud, pulsing static. I have reinstalled Movie Maker and repaired the program several times, with no solution to the problem.

What's worse is that as soon as this happens in Movie Maker, all of the sound on my computer goes to the same static. iTunes, YouTube, and any other audio plays out as pulsing static, but only after I have tried to play audio in Movie Maker.

Any help here would be appreciated as I have a movie to finish by next week and will need the audio component to work properly. Thank you in advance for your assistance!
