Ok I found the problem.

On my side, You just need  update the source position. The default  position of a sound source is sometime wrong. It will be corrected with the next update.

But if you edit your scene with your proper position, everything will be fine.

I have make some serious test with all common encoder for ambisonic and I can confirm again that everything works fine. Channel mapping is correct in all configurations (Fuma, N3D and ambiX).

I can confirm that master for  Facebook VR or Youtube VR work.
