Opening and closing Swift UI in visionOS application mutes Unity audio

1. What happened
When any native Swift UI is dismissed, Unity audio is muted. Audio may also mute immediately after the application starts if there is Swift UI that opens on application start.

2. How can we reproduce it using the example you attached
Build to an Apple Vision Pro. The attached example is just the visionOS Template (1.2.3) set to build the Swift UI sample with an looping audio track added.

Same issue is described here on the discussion forum:
