Quick Read

SpatialAudioComponent has 5 fields. None are written in the baseline — RCP uses sparse authoring, emitting each field only when it differs from the engine default.

Authored as def RealityKitComponent "SpatialAudio" with info:id = "RealityKit.SpatialAudio".

For large components, prefer fixtures.csv for fixture-by-fixture authored rows and matrix.csv for the derived variant matrix.
