I have an A7N8X Deluxe rev 2.0 and am using the onboard soundstorm sound with z-640's connected to the analog ports. The center speaker isn't putting out any sound, and the VU meter in the nvmixer isn't registering any output. When I run the wizard i get staticy noise from all the other speakers but its a high pitched whine out of the middle. I'm pretty sure I have the latest drivers and i know all the ports and cables are correct. Any help would be awesome.
