In 2021.1, Spatial Audio Initialization Settings were updated and improved. If you update your project to 2021.1, make sure you review the Spatial Audio Initialization Settings to ensure all settings are still as desired. Refer to the AkSpatialAudioInitSettings Struct Reference for details on the new settings.

Spatial Audio Portals

• AkPortalComponent has been updated to use its local X axis as the 'front' when detecting connected rooms, in order to stay in line with Unreal's coordinate system. Portals in existing levels will be transformed such that they are oriented appropriately.
• The Initial State property in AkAcousticPortal is deprecated. The initial state is now handled by the AkPortalComponent. Existing AkAcousticPortal actors will pass their initial state to their AkPortalComponent.
