Thanks.
You aren't alone my friend. I own the X99 Deluxe and Xonar Essence STX, no sound at all. Not with official drivers nor the hacked UNi Xonar. People suggested changing Gen version on the port, however that didn't help. I read about this issue quite a few times now, the fact that even the Asus representative sort-of shrugs it off worries me. Starting to think I should have gone with MSi after all, because the onboard sound is dreadful.
