How to reproduce:
1. Open the attached project
2. Open test scene ( creates default empty Unity scene with a 3D Cube, Audio Source, and TestAudioAdder game object)
3. TestAudioAdder is hooked up to MainCamera's audio listener component
4. TestAudioAdder adds TestAudioFilterRead using AddComponent
5. Play the scene
6. Expect to see "***** TestAudioFilterRead: OnAudioFilterRead ******"" in the console However, it never shows up
- Manually adding TestAudioFilterRead.cs as a component to Main Camera works (OnAudioFilerRead is called)
