RealityKit spatial audio crackles and pops on iOS 26.0 beta 5.
It works correctly on iOS 18.6 and visionOS 26.0 beta 5.
The APIs used are AudioPlaybackController, Entity.prepareAudio, Entity.play
Videos of the expected and observed behavior are attached to the feedback FB19423059.
The audio should be a consistent, repeating sound, but it seems oddly abbreviated and the volume varies unexpectedly.
Thank you for investigating this issue.
