Disable audio after the state has been visited
I've added audio sound efx to the visited states of objects on a slide. The sound efx plays when the user clicks the object. That all works fine. The problem comes when the user leaves the slide and then comes back to it, all the audio from each visited state plays all at once, creating quite a cacophony.
I've tried having the sound on a disabled state and that works the same as the visited state.
What should I do to disable the sound on the visited states once the user has clicked and heard it once?
