Hey guys,
I've recently bought a Logitech x530 with 5.1 surround sound, but when i use it, it only plays the front left and right speak and leaves
the other three speakers untouched. I've looked into it and apparently one must activate "fill speaker" for 5.1 surround sound, but when i go
to the option in Sound settings, that option isn't on the list for me. (Control panel -> Sound setting -> speaker properties -> enhancements)

How do i get this option to appear to activate surround sound?

Thanks for your help and time,
Eggy
