Custom Resolution Utility (CRU)

Guys, I need some help. It may have already been addressed but not sure I have the patients to sift through 300+ pages to find it.
So, I have a gtx 1070 in my pc that is detecting my hisense TV as stereo only in sound panel>playback devices>configure. I am also passing through the audio from my 1070 to the TV and back out again through optical audio to my audio reciever which is an older one that only has optical audio, no hdmi but still supports dd, dts, and 5.1. This setup works fairly well with my Xbox One and PS4. So the EDID is messed up from what I gathered. I tried to force it through CRU and after a bit of reading thought I had it figured out. I got it to recognize my changes but now the sound is all messed up. When I test the audio in the sound panel on 5.1 sound only comes out of front right and left speakers. Nothing from center or the rears but when I play music with vlc media player it seems to be coming out the right speakers but the sound is all garbled. I edited the default extension block and edited pre-existing audio formats to 6 channels then added dts with 6 channels. Also changed speaker setup to 5.1. I would be grateful for any assistance.
