What's wrong with my blueprint for music in a trigger box

Hi, thanks again, I’ve working on it and until now I haven’e been able to reply! One solution could be:

  1. To add a Reset node to the Do Once when the flow exits the trigger (On Actor End Overlap). This way, I’d allow track 2 to play again when re-entering.

But I don’t understand well if I should reset On actor begin overlap AND On actor end overlap or just On actor end overlap.

  1. Instead of using only Set Sound, I could also add the Stop and then Play nodes to force the music to update.
    But I don’t know if I have to put Stop and Play at: On actor begin overlap AND On actor end overlap.
