You may attach a sound to any page by using the "Add Sound" button in the page info dialog. The page sound will start every time the page is opened or brought to the front. Sounds will not stop if the page is closed. Sounds continue to play until another sound is started or until they are finished. Sounds will not restart until they have completely finished even if the sound is cued. (i.e. The same page is opened from which the current sound was started).
