Thanks James for the tips. I watched the video and we have a slight difference in behaviors, but cool to see a potential code less option for a quick test. When I try the timeline it plays audio as expected, but when I send to my Vision Pro I never hear any audio. Can you spot where I'm off?

Thanks James. I see the Timeline feature is available in XCode 16 Beta (I was using XCode 15). Unfortunately when I try to install XCode 16 Beta I get this error, "Loading a plug-in failed. The plug-in or one of its prerequisite plug-ins may be missing or damaged and may need to be reinstalled.". I guess that's an issue for a new post. I'll report back once I can get the software working.

What are the benefits and tradeoffs to using Unity for visionOS game development when compared to RealityKit and SwiftUI?
