I have an A7N8X Delux with Sound Storm and I cant get my music to play in 5.1, It is hooked up via analog to my Promedia 5.1 ultras. The front L and R play and the sub, but the center doesnt work. I ran the speaker setup in the "Nvidia Mixer" and then all the speaker seemed to work. Then when i go to play a song, only stereo. Any Idea what I should do? Thanks.
