Problem with Realtek 1150

[App4that]

I have a Gigabyte Z97X-UD3H-BK with a Realtek 1150 audio chip set. I have been using the front audio jacks and I'm able to hear in 7.1 using my G430 headphones. I tried using the rear audio right off the motherboard tonight and all I can hear using the light green plug is the front speaker audio. The center channel, sub, side, and rear speaker audio is gone. If I try and assign the light green out using the Realtek HD audio manager it is the only one I'm unable to change. When I plug in the headphones the light green in the rear is the only one that doesn't give you a pop up asking for you to assign it. I tried assigning the blue line in the headphones and I can still only hear the front speaker audio. I tried installing the Realtek driver again, no luck.
