Play Audio - All Buttons "Visited"

Don't have your source file, so I will take some guesses. To me it sounds like:

When you click the buttons, 2 things happen:

1. its state becomes visited immediately, not when you come back to 1.1 main menu;
2. this button brings you to corresponding scenes.

With that in mind, when you clicked the third button:

We met the condition to play the TTS audio [on 1.1], but the playing was interrupted, because at this time, you should be on 5.1 / 8.1 / 4.1. I don't think audio on previous page will continue playing.

Solution? [Edited: See suggest from WaltHamilton above]
