In this video tutorial, I show you my workflow for creating a single slide click to reveal that contains both slide audio, as well as additional triggered audio for each state of a multi-state object. Your instinct might be to attach the audio to the individual states of the multi-state audio but you will quickly discover that this doesn't work.

Please note: that this type of interaction will not work with the built-in closed captioning for the additional audio items so you might want to include narration text on-screen for those who require closed captioning for accessibility purposes.
