[Soundfield Submix] - Output is silent when routing sound to Unreal Ambisonics and then to Resonance

According to the official docs https://docs.unrealengine.com/4.27/en-US/WorkingWithAudio/Nativesoundfield/ an ambisonic submix can be rendered to Resonance or Oculus; however when doing so, while the sound is active in the level, no audio is heard. Sending to just Unreal Ambisonics or just Resonance does produce sound.

Test setup:

1) Launch AudioQA
2) Under Assets > Soundfield Submix open SS_UnrealAmbisonics
3) Drag the SS_ResonanceBinaural Soundfield Submix asset into the SS_UnrealAmbisonics graph. Connect the output of SS_UnrealAmbisonics to SS_ResonanceBinaural
4) Set SS_UnrealAmbisonics as the Base Submix on any sound asset. An ambisonics asset can be found under Soundwaves > Soundfield
5) Drag the asset into the editor
6) PIE

Expected Result:
 Sound plays

 Output is silent
