Comment on Do smoke detectors have little speakers inside them? If yes, would it be possible to hack them to play a little jingle?
You can if the buzzer signal is only used to trigger a secondary circuit that does what op is looking for.
That’s what I would do. Hook jumpers from the buzzer to the play button of an mp3 player. That way if the music system fails, the buzzer still wakes you up.
