1st I am a complete noob trying to learn Joomla.. I have have seen a function that works on a site..and I was wondering how they get the function to work. http://camoduck.com is the site.. make sure your sound is turned on.. when the page loads it makes a quacking noise..like a duck.. how is this function brought into the site? will someone please tell me.. thank you

This seems more like a Flash Audio. If you notice the sounds appears right after the Flash is Loaded in the Home Page. You will have two options to do this.

Upload an MP3 Module to Joomla and insert into that MP3 module the duck sound. There are a lot of MP3 modules to look at and you can make the audio start every time somebody goes to your site.

The other way is to insert the audio inside a flash file.
