Soundmanager2 stop and play

Hi im trying to configure soundmanager2, im finding it a bit confusing to have the results im after, wondering if i coul dget any help here.

This is the script im using:

<script type="text/javascript">
soundManager.url = '/SM/swf/'; // directory where SM2 .SWFs live

// Note that SounndManager will determine and append the appropriate .SWF file to the URL.

// disable debug mode after development/testing..
// soundManager.debugMode = false;

// Option 1: Simple createSound method

soundManager.onload = function() {
// SM2 has loaded - now you can create and play sounds!
soundManager.createSound('Katyperry','/music/KatyPerry-HotNCold.mp3');
soundManager.play('Katyperry');

}
</script>


I would like to know how to add a pause and resume button to my webpage, i was trying these but they would work.

<a href="javascript: soundManager.stop();"> Stop </a>
<a href="javascript: soundManager.play();"> play </a>

please help, thanks
