Stopping audio from playing when you return to the main slide
I have a slide set up so that the learner hears the intro audio and then clicks on an object on the main slide. They must click on the objects in order which works perfectly. Once they finish viewing the layer, they click on an object on the layer to return to the main slide so that they can click on the next object to view the next layer and so on.
My problem is that when they return to the main slide the audio plays again, which they have already heard. Is there a way to stop the audio from playing each time they return to the main slide?
