Playing embedded sound. Stops in the middle

Hi.

I try to play an embedded sound clip like this:


[Embed(source = "../assets/glass.mp3")] private var SoundAsset:Class;
var SFX: Sound = new SoundAsset();
SFX.play();

I get this sound played, but it cuts after a few ms, while the sound clip is about 1 sec.

What could be the problem?

TNX!
