Another MovieMaker sound question

[WatchYourStep 0]

Sorry I'm having trouble even when I read the help section.

Here's what I'm trying to do. (This is with MovieMaker by the way.)

Video starts listening to people chat.
Voices fade music enters.
Music fades voices come back in for a few second.
Then voices fade and music picks back up where it left off. Is this possible?

I use the slide button for the audio but when I play the video back the sound comes from whichever side the slide is at. I know it's a simple fix but I can't get it.
