How To Play Audio Using SoundManager 2

Simple ID / URL method:

And, setting the volume:

soundManager.setVolume('mySound',50);

More flexible method supporting option parameters as an object literal:

  id: 'someSound',
  url: '/path/to/some.mp3',
  volume: 50,
  onload: soundLoadedFunction
});
mySound.play();

Using SM2 on your site

How to include SoundManager 2 from HTML, and some basic event handlers.

Include the SoundManager 2 core script, tell it where to look for the flash .SWF and provide an onload() handler.

<script type="text/javascript" src="/path/to/soundmanager2.js"></script>
<script type="text/javascript">
soundManager.url = '/path/to/swfs/';
soundManager.onload = function() {
  // SM2 is ready to go! 
  // soundManager.createSound(...) calls can now be made, etc.
}
</script>
