I have no sound when I record from my webcam in windows movie maker.  I do have sound in Skype, windows media player, and all other functions of the computer.  I have Alt F and selected each sound option one at a time and attempted to make a recording with no success.  I am currently using Windows 7 and the version of movie maker that said it was compatible.  Not sure what to do from here.  I was excited about this program an hour ago and now, not so much.  Please help me.  Thank you!
