I have Windows 8.1 on a Lenovo Ideapad Yoga 13 with an intel corei7.  Windows Media Player plays all my .mp3 files and .wma files fine.  However, after importing .mp3 or .wma files into windows live movie maker 2012, I cannot hear the audio.  I imported 6 pictures and an .mp3 file and created a movie and then tried to play it using Windows Media Player.  The audio played fine in the completed file in Windows Media Player, so the issue seems to be with Windows Live Movie Maker.  Does anyone know what the solution to this problem is? 

I have tried uninstalling and reinstalling Windows Live Movie Maker and that did not help.  I made sure that I had all critical windows updates installed also.  There are 4 optional updates that I have not installed (Silver Light, 8.1 system update, Bing desktop and bing search bar).  I doubt these will change my audio issue in Windows Movie Maker 2012.

Do you know of something I could try?
