How to prevent audio from playing when returning to slide

Hi John,

I have followed your advice (except that I called the variable "playonce") as I was following another post, but it just does not work for me.  The audio will start again when I return to it. The variable is working because it chances to "true" (I added a text box with "false" on it) Can you help? please see my screenshots with the triggers I have added.

I have tried different things with the slide properties " Resume saved state" and "reset to initial state" and it does not work with any of those two.

I wonder if I should add more variables considering that on the screen that the audio is played it is also shown different images aligned with the audio and I want the learner when they return to the slide with the audio to see the latest images that were displayed. Should I add another trigger? or should the audio trigger be enough?
