The sounds weren't actually working, they would show an activity with a broken format (double-nested activity markup) and nothing would play. It seems like something got messed up somewhere along the way. Fixed the issue with the activity rendering, and made the audio clips play and be clickable (to re-play). Also went ahead and updated the format to be a little nicer (with speaker emoji icons).
