So I have a global parameter that is referenced in an event. With only this reference the event plays just fine. This changes if I automate Reverb based on the global parameter in a Return track. Suddenly UE4 won’t play the sound even tough its getting triggered. Checked the profiler and fmod is not showing the “playing” event either. Any input? ---

Are you getting any errors or warnings in the logs? What versions of FMOD and UE4 are you using? ---

It was just a corrupt event it seems, I duplicated, renamed it and now it works just fine.
