iOS app Sound don't come back after home_btn iPad.

Hello,

I hope somebody can help me.

I have a problem with my  IOS app.

My app works great except when the user press on the home_btn iPad

and Siri comes to the foreground,it maybe will happen because the app is for children,

then the music stops but did't come back. So my app crashes a little big later.

the code in my app is:

stage.addEventListener(Event.ACTIVATE, function(event:Event):void

{

stage.frameRate=36;

SoundMixer.soundTransform=new SoundTransform(1);

});

stage.addEventListener(Event.DEACTIVATE, function(event:Event):void

{

stage.frameRate=0;

SoundMixer.soundTransform=new SoundTransform(0);

});

I also tried the code:

NativeApplication.nativeApplication.executeInBackground = false;

Can somebody help me?
