I'd really appreciate some help with this, as it's driving me nuts. I have a Shuttle 35N Ultra MB with Realtek ALC650 6 channel on-board. I bought Logitech Z-640 speakers, and I can't get any sound out of the center *or* rear speakers. I know the speakers are fine, since I hooked the rear into the front speaker jack and they worked, and I tested the "Matrix" feature which gives sound out of the center speaker without using true surround, and the center was fine too. The front speakers and the sub are working fine, and I just get an extremely faint whisper on one of the rear, but that's it.
I have the green (front) cable connected to the "line out" jack, the black (rear) to the "line in" jack, and the orange to the center jack, which I'm 99% sure is correct. I know the center shares it's jack with "mic in" and the rear with the "line in" - NVidia's driver has an advanced menu where you can check off that selection. I also changed the menu to "5.1 surround speakers" - still nothing. Is this a jumper setting? A driver issue? If that's the case, is there a download that would help?
As I said, this is driving me nuts - any help would be much appreciated.
