Re: Sound: Center and Subwoofer don't work
first don't be excited because I won't help you ...
Just to mention that I have EXACTLY the same issue as you described (actually I first thought it was my post),. I posted a very similar request for help on the nvidia forum but never got any answer... tried it all > alsa / nvaudio, mixers, kernel... gave up, I was wasting too much time.
May be if enough people post exactly the same requests the NV guys will react ??? who knows. In the mean time I will try alsa on the new machines I bought, they have 7.1 sound (asus boards).
