Play Audio using Player's Play/Pause Button

I would like to add audio to every slide in my course, but I would like the audio to be optional and not play automatically. I want to utilize the Player's play/pause button because I do not want to add custom buttons to every slide to control the audio. 

The only way I have figured out how to control the audio with the Player's button is to insert the audio, then add a trigger that pauses the timeline when the slide begins. Then the user can press "play" if they want to hear the audio.

Is there a better way to do this? I have a bigger project coming up, and adding that trigger on every single page is going to be time consuming. If I can avoid that, I would like to.
