Gaming motherboard doesn't have 5.1 surround and tritton headset not working


Mar 3, 2016
Hey guys so i have a gaming rig...

GTX 760
i5 4460
Motherboard: MS-7850

and basically my motherboard or sound card does not have 5.1 surround sound it only has the Green audio jack Pink Mic jack and a Blue jack. I have purchased a Trittion 5.1 surround sound pro plus headset and it does not work to its full potential, there are buzzing sounds and does not even sound like a gaming headset, the quality of the sound is very poor. Does anybody have any solutions?!!
