Layer, back to Base, no audio repeat
I wonder if anyone has any advice. I have a base layer with audio. Users click an object on the base to go to Layer 1, and then click a button to return to the base layer to click another object to get to Layer 2. This action repeats for several layers. Problem is, every time I revisit the base layer, the audio repeats. How can I disable it after the initial play when the slide opens?
