Hy everyone,
I use this function to start the music in my project
function tocar() {
soundFactory.addEventListener(Event.COMPLETE, completeHandler);
soundFactory.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
soundFactory.addEventListener(ProgressEvent.PROGRESS, progressHandler);
soundFactory.load(request);
song = soundFactory.play(); }
Now i wana low volume of the music. I thought it was something like song.volume = 90; but i was wrong 
Can u guys help me on this???
