It'll happen again; mark my words. Give it a month or two. Windows 10 and Uni Xonar drivers made no difference to me. Although the solution I've switched to, the Powercolor Devil HDX 7.1, has its own problems: no headphone gain control so I have to turn the volume down to 15 - 30% and sometimes usually the card doesn't start up on warm reboots. My next computer audio solution will most definitely be external DAC + AMP.
