Can we have at least 7.1 surround sound?

I have noticed with ROG Theta 7.1 surround headphones that back surround channels are not used, the game only sends to the SIDE channels.

I can even SEE the problem while game is running using the Armoury Crate ROG software running on side monitor while game is playing. I can see that the RL/RR channels are completely flat and silent - nothing at all coming from them. Only centre FL/FR and SL/SR have sound.

Which means the "surround" from the game ONLY comes from front 180 degrees of sound field - nothing at all from rear 180 degrees.

And yes the main characters voice is barely audible for some reason. Fixed after reboot.

I grabbed below image as BF2042 was running and lots of sound going on around me. Only 4 channels (and center) do anything.

The two REAR channels are dead always.

I understand that game says it uses a 5.1 audio mix in surround, but with many of us having as much as eight extra CPU cores sitting around doing nothing (over the eight cores it apparently uses) couldn't high-end PC users use at least one extra full core to do proper full 7.1 sound processing?

IDEALLY WE WOULD GET DOLBY ATMOS TO DO PROPER GAME OBJECT MOTION TRACKING IN FULL 7.1 (AT LEAST) BUT MAYBE NOT NEEDED IF GAME ENGINE CAN TRACK OBJECT LIKE ATMOS CAN
