Sound trouble

I'm having issues with my sound playing when I don't want it to.

I have included a Marker and attached a sounds to the marker. Within it I have set sound to play and stop based on clicking the marker and leaving the marker.

Within the Marker I have options to navigate away from the slide for instructions on how to complete. If you click for instructions it is all fine. However once the instructions are completed and they return to the page it starts playing the sound from the marker. Which I want to stop.

 

I created a way to stop it but duplicating the slide and returning them to a different version of the slide but this isn't ideal.

Originally I had created visted states so people knew where they are at. But by creating the duplicated slides and returning them to technically a different slides I can't include the visited states because it resets everything.

I have tried (what i think is)everything.  I have created slide layers with the sound, this didn't work.

 

I would appreciate any help I can get.

 

Thank you
