You could use the "playstopped" message in the card or stack script to check which player has stopped and
take appropriate actions.

If you need to see if the sound has really ended and the player has not been stopped manually by your user(s),
in case you have implemented this, you could then check "the currenttime" against "the duration" of the player, capisce?
