Sound replication issue

I’ve been trying to add sound to my game and I’ve run into a bit of a problem.

When I tell the server to spawn sounds attached or at a specific location only one client can hear the sound. It’s always the client that spawned in last. The rest of the clients and the server can’t hear a thing.
I’ve been trying to solve this now for a while but I’m getting nowhere.

The part of my character blueprint that handles the sounds

One of the sound cues, the rest looks pretty much the same. All om them use mono sounds

Shot in the dark here, ancient post but giving an answer in case anyone else comes across this.
In the Editor Preferences > Level Editor > Play > Multiplayer Options, try checking Create Audio Device for Every Player.

My guess is that UE4 has only one audio process going when you play on one pc, PIE, and assigns the process to the most recently created client.
