AkSoundEngine.PostEvent to Global Scope not working on Unity 2022.3.5 and Wwise 2022.1.6

+2 votes

I'm having some trouble with posting a Wwise event to Global Scope from Unity.
I'm using Unity 2022.3.5 and Wwise Integration 2022.1.6.8263.2826.

IIRC, doing something like:

  • AkSoundEngine.PostEvent("Test", null);

With "null" as the in_gameObjectID parameter should post the event to Global Scope.
But I just tested this on a new Unity 2022 project, and this isn't working anymore.

This issue contradicts the following info from the Wwise docs (API Changes and Limitations)
https://www.audiokinetic.com/en/library/edge/?source=Unity&id=pg_limitations.html

  • PostEvent() and GameObject-related APIs now accept null as the GameObject input argument to affect the global scope.

If I set a Unity GameObject on the in_gameObjectID parameter, the event plays correctly.
But if I set the parameter to null, the following errors appear in the Unity console:

Wwise: Invalid parameter in_GameObj in function call AK::SoundEngine::RegisterGameObj
