How to configure virtual surround sound

How to configure virtual surround sound (5.1 / 7.1) for headphones to playing windows games via flatpack steam / proton / wayland / fedora 34 ?

Fedora 34 with pipeware I change it in the audio settings and it seems so. I get all six channels, but it’s not true, I only have sound from the front two.
