audio in internet explorer and cross-browser

I have an audio element in a webpage for a client and i have coded it as well as i开发者_JAVA百科 can but i still can't get it to work on All browsers. I know cross browser and browser editions (i.e. internet explorer 6,7,8,9 ) with audio is tricky but there has to be an answer here. Can this be done and without needing browser plugins? Here is my current code.

<audio  preload="auto" autobuffer autoplay="autoplay"> 
<source src="http://brodysfurniture.com/wp-content/themes/Brodys/images2/08_Track_8.mp3"/>
<source src="http://brodysfurniture.com/wp-content/themes/Brodys/images2/08_Track_8.ogg" />
<source src="http://brodysfurniture.com/wp-content/themes/Brodys/images2/08_Track_8.wav" />

</audio>

I would look here for some answers. I personally have made a page that uses the native <audio> element but provides a WMP fall back for the less tech savvy users that insist on using old deprecated software.
