Logitech Z-640?realtek ALC650 Problem

Deeg · 08-03-2004, 08:14 PM

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.

I'm having the same problem with my Logitech Z-640s. I can get sound out of the front and center speakers, but the rear speakers are very low. I've tried adjusting the cables, but nothing seems to work. Any ideas?

I actually found a solution to this (at least for me). I went to Realtek's website and downloaded their latest driver (about 10 megs). Fixed the problem. If you have ALCC650 sound, give it a try.

I also have the z640, and i also can't get sound from the back speakers. I use matrix to get center to work, but the back are just useless right now. and it truly is ****ing me off. The extra 2 jacks needed for the 5.1 card i have are on a little card that doesn't even connect through pci, but thorugh a cable staright to the mobo. It came w/ the case, a soyo barebones kit... the heck am i supposed to do?

In my case, it turned out to be a driver problem - I downloaded the Realtek drivers and it totally fixed the problem. GIve it a shot...
