how to duplicate a Sound object in flash

Question

I need to duplicate / clone a sound object in flash.

I tried using various clone methods such as this one here

http://blog.another-d-mention.ro/programming/how-to-clone-duplicate-an-object-in-actionscript-3/

var snd:Sound= UtilFunctions.clone(e.sound) as Sound

But my cloned sound object comes back with zero bytes loaded and zero bytes total.

I don't really want to get into extracting pcm into bytearray for memory reasons.
