    I'm using ARFoundation with Addressables that have prefabs with timelines. I'm having issues with making the 2D sound 3D sound using spatial blend for these timelines.

    Workflow:
    - I have an Audio Listener on the ARCamera
    - I instantiate a prefab from addressables that has timelines
    - There is an audio clip on the timeline that has an Audio Source attached
    - The Audio Source (in the prefab) has Spatial Blend = 1 & Linear Rolloff (but no audioclip since it is on the timeline)
    - The Timeline Audio has Spatial Blend = 1
    - No Sound when I play it in AR

    When I use 2D sound, everything works fine, but I need 3D sound. I have tried different options between the timeline audio spatial blend and the audio source spatial blend but nothing works - still no sound.

    Any ideas?

    OK so after some messing around, it seems that it works when I attach the Audio Source to another game object instead of having it on its own.... I guess I can just make an invisible 3D game object and attach it to that, but it seems strange that I can't just have an audio source on its own.
