Beginner's question about sound object and movieloading

I have a file that successfully plays a sound until I load the file into another file.

I’m loading minor.swf into major.swf.

The code in minor.swf is:

music = new Sound();
music.attachSound(“song”);
music.start();

The code in major.swf is:

loadMovie(“minor.swf”, “holder”);

I’ve verified with a graphic and a global variable that minor.swf is successfully loading, but its sound doesn’t play.

Help would be appreciated.
