Buzz.js: how to make sound play from nested symbols?

Hi,

I loaded buzz.js and it is playing fine with this code:

var mySound = new buzz.sound("soundfolder/myAudio", { formats: [ "ogg", "mp3" ] });

mySound.play();

Now, if "var mySound = new buzz.sound" is in Stage.creationComplete, how do I play this sound from a nested symbol? Can someone give me a code example? Thank you
