I am having a problem with my system's sound using Movie Maker.

I am running Windows 10 on my ASUS laptop and every time I playback my video that i have been editing, my PC's sound immediately gets muted. I have tried detecting the problems and no problems were found and my volume was at its max and there was still no sound. This only happens with Movie Maker in Windows 10. Is there a bug within Movie Maker or is it just my PC?
