I have project that requires the audio/visual to sync. I have a main swf that loads other external swfs (which has streaming sync Sound). So, to load ‘movie 2’ I have to call the following function:

function clickHandler2(event:MouseEvent):void  
{  
SoundMixer.stopAll();  
request.url = “movie2.swf”;  
loader.load(request);  
}

Problem is this stops the background music in the main swf. Is there a way just to stop the loaded swf sound and not background music? I tried loader.SoundMixer.stopAll() but only get errors.
