If you want the slide show to end automatically, then you will need to have
the slide advanced automatically. Click Slide Show > Slide Transition. Set
advance slide automatically 00:00.
If the user is navigating manually, then I suppose the user will press the
enter key when the last animation is finished for the slide to end? If you
want the sound to stop after all the animations, select the Sound Icon, click
Slide Show > Custom Animation. Click Add effect > Sound Actions > Stop. Set
the Stop effect to after previous.
