loop dont dispatch ended event?

[papadasoft]

sfx[valores[0]] = new buzz.sound(valores[1], {
	formats: [ "ogg", "mp3", "aac", "wav" ],
	preload: true,
	autoplay: true,
	loop: valores[2]=="1" ? false : true,
	volume: valores[3]
});
console.log("Colocando ended.");
sfx[valores[0]].bind("ended", function () {
	sfx_actual[valores[0]]++;
	console.log("Canal: " + valores[0]);
	console.log("Repeticiones: " + sfx_repeat[valores[0]]);
	console.log("Actuales: " + sfx_actual[valores[0]]);
	if(sfx_actual[valores[0]]==sfx_repeat[valores[2]])
		endSfx(valores[0]);
});

This code show the message 'Colocando ended.' but never show Canal:, Repeticiones: etc...

What appens? Thanks!
