Audio on slides: How can I get them to replay without re-starting the slide

Hi, Trevor -- Are you thinking of having an effect like looping the audio? You could achieve that effect by utilizing the steps listed here. Please let us know if that is not what you had in mind! 

Loop or no loop... just put the audio onto a layer and set it to "reset to Initial state".

You can then "show" and "hide" your audio track as often as you want to by using any trigger event you like, e.g. button trigger.

Thanks for the idea, Jan!
