WP Audio Player Autostart

I am trying to get the audio player to “autostart” when opening the page, I have coded it to the specs instructed by the plugin programmer. The audio file works fine, but still no autostart. Here is the php code:

<?php if (function_exists(“insert_audio_player”)) {
insert_audio_player(“[audio:babysshort.mp3|autostart=yes]”);

The page is here: http://www.babysburgers.com/

Any help appreciated.
