I have my realtek setup on 5.1 with my speakers which works fine. Left, right, center, sub all working. When I plug in my headset into my speakers it only plays left and right. It used to work but after reinstalling windows 10 and all the drivers for my mobo my headset no longer plays surround. I have been searching for a solution and have tried changing settings around but can't get it to work again. Any help would be greatly appreciated.
EDIT: Headset is Sennheiser PC350 connected through 3.5mm
