I don’t think it’s a replication issue, I also thought it could be. But then it would not work either when having two players, and it does work, only the standalone option jinx it. TO be certain, I also created a spawn audio on location which is triggered by a key. Agreed that should only work on the client triggering it, I believe, but it doesn’t anyway. I also tried spawning audio on a run on server custom event, triggered by the keypress. No success.
