AS3 Code - Sound not playing - actionscript-3

Question

I'm trying to play sound in as3 code using an external mp3 file.
So here's the code I am using:
private function playSound():void
{
trace("loading sound");
var mySound:Sound = new Sound();
mySound.addEventListener(IOErrorEvent.IO_ERROR, handleIOError);
mySound.load(new URLRequest("Menu.mp3"));
mySound.play();
trace("playing sound");
}
private function handleIOError(evt:IOErrorEvent):void
{
//handle error if needed
}
The music just doesn't play at all.
The traces "loading sound" and "playing sound" appear so the code is being run.
The mp3 file Menu.mp3 is in the same folder as the .fla file used to run the project. Is this the correct directory? I tried moving it around but still couldnt play the sound.
Any help will be appreciated, thanks!

Answer 1

I have a few suggestions that might help:
Declare mySound as a class level property. The garbage collector might be disposing of the variable prematurely since it is local.
mySound.play() returns a SoundChannel object. Try storing this in a class level property.
Add an event listener to the sound for Event.COMPLETE, right before loading the sound. Try playing the sound after this event occurs. As it is, you might be trying to play the sound before it has loaded.
private var mySound:Sound;
private var mySoundChannel:SoundChannel;
private function playSound():void
{
mySound = new Sound();
mySound.addEventListener(IOErrorEvent.IO_ERROR, handleIOError);
mySound.addEventListener(Event.COMPLETE, handleLoadCompletion);
mySound.load(new URLRequest("Menu.mp3"));
}
private function handleLoadCompletion(evt:Event):void
{
mySoundChannel = mySound.play();
}
private function handleIOError(evt:IOErrorEvent):void
{
//handle error if needed
}
Edit:
After reviewing the docs, I think that suggestion 3 isn't necessary.
