Content creation

Hi, would like to enquire, is there any way to include audio (sound effect for correct and wrong answers) for this game? https://h5p.org/flashcards

If audio can be include, what code should I include? I am not a programmer so some help will be greatly appreciated. Thanks! 

We are using H5P in our moodle to create interactive content. we are unable to create more than 50pages in interactive book. how to increase the page count in interactive book?
