This took me a long time to figure out so hopefully the logic might come in handy for someone else trying to do the same thing!
I decided I would like the sound only to play on the door becoming fully shut, but not when the game starts, so this setup in blueprint allows the sound to play when the door closes fully only after being opened (any amount of opening resets it).
Door Is Closed is an event at time 0 and Door Has Opened is an event at time 0.1.
