Audio Trouble shoot made me lose my 7.1 surround sound as one of my playbacks audio. HELPPPP!!!!

I did a audio trouble shoot in my settings and while the trouble shoot was running it said something about turning off the audio enhancements on the 7.1 surround sound for better audio so I accepted and then it just said that it removed the whole 7.1 surround sound playback so now when I open the Razer Surround Sound software and I turn it on it cannot be active because I cannot select the 7.1 surround sound as one of my audio devices. Please help me!!
