WP Audio Player: Play audio to 'new' site visitors only

I have WP Audio Player configured to only play on the home page; where it’s also set to autostart.

I’d like to configure it so that it only plays to new visitors to the site, and isn’t triggered by internal clicks back to the home page. (Similar to this post – http://wordpress.org/support/topic/set-cookie-once-user-hits-pause)

Anyone know how I might go about this, or if it’s not possible with this plugin, know how it can be done?

Cheers
Dan
