Inserting code in editor

Hi, I am trying to insert some code into my blogs in oder to display an mp3 player (this one)

The code I am using is as follows;

{s5_media_player media=[audio] audio_mp3=[/images/podcasts/TheEssay.mp3]}

However instead of showing the player, it shows the actual code. I have tried the standard Joomla articles and it works no problem.

Image attached.

I have also tried disabling the editor in Easyblog but this makes no difference. I have also removed the text filers for registered users.

An ideas?

Thanks
