Windows Sonic for Headphones, how to configure

Hi all,

I stream my PC to my Xbox Series X using Apollo / Moonlight. I would like to use Windows Sonic for headphones, which i can select for the virtual speakers in Windows, but which i can also select in the Xbox settings.

I am wondering what the correct configuration is.

-Should i select it on both the PC and on the Xbox? I am wondering if double processing might not be the best.

-Should i select it only on the PC and set the Xbox to stereo? Would it then still be the Windows Sonic signal, or would the stereo setting on xbox mess it up?
