[[MP3Loader] Tween volume]

I want to tween volume of loaded mp3 via LoaderMax.

 

Loader>

....
aQueue.append( new MP3Loader(audioPaths[4], {name:"mymusic", repeat:-1, volume:0, autoPlay:true}) );
...

everything is ok here

 

 

This code doesn't work [mp3 is loaded]

TweenMax.to(aQueue.getContent('mymusic'), 1, {volume:1, ease:Linear.easeNone});

 

 

Please help!

Thank you
