AS3:External SWf sound not playing after loading it in parent swf

hello,
Please help me out
I have a game swf which is needed to be loaded in a parent swf. It loads but doesn’t plays sound. I checked it independently( double click on game swf) to see whether sound plays or not. I got to conclude that game swf works fine but after loading it in other swf, it works without sound.

Thanks a ton in advance for help!!
