Associating sound to different objects in a slide

What guidance would you give for associating different sounds to objects on a slide in AP?  

Clarification:  Assume I have three buttons on a slide.  What I'd like to do is associate a sound to each button.  (Say, a "click," for example, when the user chooses that button in the published course.)    I know it's possible to do this in PowerPoint.  But, sounds associated with an animation in PPT don't transfer to AP.    

Thoughts?
