7.1 Surround Sound Not Showing up in list of Audio Outputs

I recently had a serious audio issue with my computer and uninstalled all my audio drivers from my control panel to so my computer could hard reset itself and download it's audio drivers again. I also uninstalled the 7.1 surround sound application. Then I reinstalled everything from my basic sound drivers and the 7.1 surround sound application. However, when I look through my audio outputs I can't find the 7.1 surround sound audio output.
