I'm using an Asus Sabertooth FX990 R2.0 board with Win 8, and only my Digital audio is working. I use digital in my room, but I took my PC out of there so I could use the larger tv screen in my basement. I've tried both the front connectors and the back connectors on my computer, but neither of them work. I've tested those with headphones and speakers just to make sure that the devices work, and neither produce sound. Windows Audio Control Panel shows that sound is being produced or at least detected. The odd thing is that these 3.5 jacks used to work before I used digital, but not even re-installing the drivers from ASUS worked.
