I have an ASUS A7N8X motherboard and I cannot get the sound to work on my speakers. I checked the manual and I cant seem to find any jumpers for the rear line out jacks. I am also trying to get the front audio panel to work as well. I have front audio wires that are labeled Ear-L, Ear-R, Mic Data and Mic Grd. Any idea where they get attached to on my motherboard. Sound is working fine in device manager and sound is not muted. Speakers are on and plugged in correctly. Any help would be greatly appreciated.
