maybe

for(var i:int=0; i<swfA.lenght; i++){

     tl["loader_"+i].contentLoaderInfo.SoundMixer.stopAll();

}

Would be something like:

tl["loader_"+i].contentLoaderInfo.channelName.stop();

To each sound

Or maybe you'd need a function within the SWF each stop all sounds using SoundMixer.stopAll();

, and call that function from your main movie.

tl["loader_"+i].contentLoaderInfo.myFunctionMute();

I have about 70 sounds in my two external swfs. Do I have to stop each one?

//---

more than likely, yes. i guess it would depend on how you have the 70 sounds set up in your external swf... i mean:

do you have 70 named movieclips on the external swf stage with a separate sound in each one? and do they each have a stop() action in the first frame?

or

do you tell your external swf to go to a certain frame label which plays a sound on the timeline at that label?

or

are your 70 sounds created dynamically with code and told to .start()?

also keep in mind, a loading swf will start to play even before it is completely loaded. so instead of when it's completely loaded, try stopping the loaded swf with a listener for "init", which is when the loaded swf enters its first frame:

function loadNextF():void{

                tl["loader_"+index] = new Loader();

                tl["loader_"+index].name = index.toString();

                tl["loader_"+index].contentLoaderInfo.addEventListener(ProgressEvent. PROGRESS,progressF);

                tl["loader_"+index].contentLoaderInfo.addEventListener(Event.COMPLETE ,completeF);

               tl["loader_"+index].contentLoaderInfo.addEventListener(Event.INIT, initF);                                     

                tl["loader_"+index].load(new URLRequest(swfA[index]));

}

function initF(e:Event):void{

                SoundMixer.stopAll();

                var mc:MovieClip = MovieClip(tl["loader_"+index].content);

                mc.gotoAndStop(1);

explain the setup of the sounds on the timeline of the external swf.

i gave 3 possible scenarios. could it be one of those? or something different?

dont forget, while the swf is loading, it is playing... you dont tell it to gotoAndStop(1) until it completes loading... do you hear the sounds start from the beginning twice?

sounds like your loading swf is not stopped.

please try adding this. basically, it's telling the loading swf to gotAndStop(1) as soon as it enters it's first frame, whether it's finished loading or not:

function loadNextF():void{

                tl["loader_"+index] = new Loader();

                tl["loader_"+index].name = index.toString();

                tl["loader_"+index].contentLoaderInfo.addEventListener(ProgressEvent. PROGRESS,progressF);

                tl["loader_"+index].contentLoaderInfo.addEventListener(Event.COMPLETE ,completeF);

               tl["loader_"+index].contentLoaderInfo.addEventListener(Event.INIT, initF);                                    

                tl["loader_"+index].load(new URLRequest(swfA[index]));

}

function initF(e:Event):void{

                SoundMixer.stopAll();

                var mc:MovieClip = MovieClip(tl["loader_"+index].content);

                mc.gotoAndStop(1);

}

//---

another thing you can do simply is try putting a stop() in the first frame of the loading swf (on a separate layer, of course)

you're welcome
