And you have solved so i will just simplify it for newcomers.
I had same issue and Not even simple play/spawn sound will replicated so always “multicast” the sound and for actions like open door like stuff just “run on server” will work.
Sound do work but need to me multicast not just spawn as it will be spawned but on server and server will not send that audio to client so use multicast for any action/sound that is required to be played/perform by all players/Clients
