Toggle Sounds on trigger

Alright I have been looking around for an answer and I feel that since I can’t find it on Google it must be so easy to do but I am just too tired to figure it out.

What I am trying to do is have a safe that has a trigger box around it and I want a sound to play when triggered. I want to make it toggle on and off. I can get a sound to play but can’t disable or stop it without destroying it which then wont let it play again.
