Requiring Markers to Complete before advancing

I am trying to require the user to complete the audio file that plays when they click on a marker.  There are multiple markers on the page and I want the user to complete them all before advancing to the next slide. The audio is attached to the marker.  I have tried changing the state to visited "when content closing" but the text box does not automatically close.  I have the slide set up so that the user can see the next button but a layer pops up telling them they need to complete all interactive elements if the markers are "normal".  Once both markers state is visited, I have a trigger that says the next button advances to the next slide.

Is there a better way to go about this?  At one point I tried using variables but it just got too confusing.  Any ideas are welcome.

Thank you,
