Ari,

  This file shows how you could set up what you're asking for.  There might be a more elegant way, but I have it so that if you go to another lay, or another slide and return the sound does not replay, only on the original entry.  You could run into a problem if the person does need to replay the sound, but then again you could add a replay audio button if needed to resolve.
