How do I add a click sound after each slide?

I am attempting to add a click at the end of each slide without the mouth path. The project is made as a video simulation without user interaction - each slide jumps to the next at the end of the timeline. I'm not using the mouse cursor because it shows during the entire scene.

How do I add a click sound at the end of each slide? 

p.s.- the AI Audio option is disabled.
