OMG so the sound when it is not working i change to stereo and it works it just not works on 5.1. what else.. i have sound. I dont know if it is 5.1 but i have it. It just dont work on some games and as nvidia told me its not surround if i dont have the receiver recognized. Hope i included all. I need all the help i can get. This story goes months back.
