I have an A7N8X-X with Debian testing. I've installed the nForce 1.0-0261 drivers and all is good. Except, the speaker socket on the rear panel does not produce sound. At the moment I'm using the headphone socket on the front of the case which works fine. I've put up with this for ages - now it's time to figure it out properly. Otherwise the mobo and nVidia nForce drivers are working well.
A7N8X-X rev 2.00
Google seems to think this problem is mine alone
