I recently installed Windows Essentials 2012 so I could use Movie Maker.I can import my videos but have no audio.The speaker on the left in the volume control within MM has a red X on it ,like its muted .Nothing I have done works. I have tried going into the audio settings and turning that off then back on which works until I reboot my laptop.I don't feel I should have to do this all the time.Please help. Thanks
