If you need instructions for coding a new HTML 5 audio player, I suggest visiting this site.

dev.opera.com

The simple code for implementing an audio player in html 5 is:

<audio controls preload>
    <source src="http://yourserver/rockandroll.ogg" />
    <source src="http://yourserver/rockandroll.mp3" />
</audio>

I recommend that you you create audio files in mp3, ogg and wav formats to ensure that your player will work in any browser.
