No sound with imported swf file

I have created two flash movies. Flash Movie 1 is a menu page and the Flash Movie 2 is going to be put in the upper left corner of Flash Movie 1. If I open Flash Movie 2 in a browser I can hear the sound that the movie was designed to play. But when I embed Flash Movie 2 inside of Flash Movie 1 the sound does not play. All of the motion that Flash movie 2 was designed with does play while embedded. The code I used to embed Flash Movie 2 is: loadMovie(“RPTrain.swf”, PlaceHolder); and PlaceHolder is a rectangle that was turned into a movie clip.

Thanks in advance for the help … Michael
