For one shots that need to continue playing across scene loads, the safest approach is to create the EventInstance manually (instead of relying on a StudioEventEmitter on a scene object) and let it live in a DontDestroyOnLoad manager. Once started, the instance will keep playing until it finishes, even if Unity loads a new scene.
This usually means the sample data wasn’t fully loaded when the instruments triggered. Could you please double check that the assets aren’t set to Stream, and that Preload Sample Data is enabled on the events?
