It is a problem with the film shot editor,, if you really want the correct sounds make another film of the scene you are trying to capture without using the shot editor, then paste it in the soundtrack portion of you film maker!
Or you can go to your aces high sounds and drag them into you film maker files, I have done both, it works well enough, I'm making a movie now with GV's and most of the films are over an hour so I am having the same problem over and over!
glad you reminded me to fix my soundtrack!
