Captivate Classic - Pause Quiz Audio

Captivate Classic 11.5.5.553

The project requestor wants a narration for the quizzes in this Classic project. Putting the audio on the timeline means that if the user jumps ahead of the narration then the audio attached to the response objects plays simultaneously with the question audio.

In the past, I had the question audio attached to a "Play Question Audio" button and that allowed me to terminate the question audio when the response text was displayed. But the requestor wants the quiz audio to play automatically upon slide entry.

I am looking for a way to either stop the quiz audio OR delay the Submit response until after the quiz audio has finished playing. My trials with various Advanced Action approaches are not working. An example of what doesn't work is to have an AA that plays audio, delays next action by xx seconds, then continues. The result is that when the Submit button is clicked, the AA is apparently ignored.

Is what I want to do just not feasible in Classic?

Please let me know questions.

Thank you!
