I am trying to use Windows Movie Maker to take a photo and add music from an mp3 file.  Movie Maker only loads 7 seconds of the music file and there is no sound.  Do you know what could be wrong?  I'm pretty surprised.  This music file plays fine on WMA.  Movie Maker version is 2012 16.4.3508.0205.

I also tried to play a movie in Movie Maker.  Again no sound.  

I've never tried Movie Maker on Window 8.1.  Is there an issue with this combination?
