How to EASILY create a slide with buttons to display different images and play different audio for each layer.

Recently a coworker came to me with an issue where he wanted to have buttons, that when clicked, would show a different layer/image and play different audio.  The issue he was having is the user had the ability to click additional buttons before the initial layers audio completed.  As a result, several layers audio would be playing at same time.  There are several ways to set this up, but what I like about my setup posted here is the simplicity of it.  It places the images in the visit state of the button, which in turns means less triggers are needed.  I then created triggers to state when button visited go to layer X and play media.  Set it so user can't advanced til media completes.
