nForce2 (onboard) only 2 channels have sound..

[Dj_Jestar]

and no matter what I try, it will only play out of two channels..

Any suggestions? Latest nForce2 drivers installed from nvidia.com, nvmixer "Speaker Wizard" doesn't play sound from rear's nor sub..

oh and I've tested with 3 different pairs of headphones, and a set of 5.1 speakers. Even plugged the same headphone jack into all sockets, and only the left/right is outputting, and "headphone" jack.

Have you tried the speaker setup thing in the control panel?
