Realtek HD speakers fulfill option missing

[Marty11]

Hey,

I have Asus Maximus Hero VII mobo and I have installed provided software for sound management. Realtek HD (Supreme FX) software but I'm not able to select speakers fulfill option. Therefore anytime when sound isn't 5.1 only two speakers are active.

Could you give me any hint how could I solve this?
