Play audio when lightbox closes
I created a slide that plays an opening narration then opens a lightbox. After the lighbox content closes, I want the slide to play a closing narration. I can't figure out how to get the audio to play when the lightbox closes. I tried using a Boolean variable by changing its value when the lightbox's timeline ends and creating a trigger that plays the audio media when the value of the variable changes but that didn't work. Can anyone recommend an approach to getting an audio to play when a lightbox closes?
