ok I just put the sound card in my comp today and did a fresh install of windows 10 pro on first start up into windows my sounds works fine but after I update windows I loose sound I got it hooked to a reviever via 3.5 to rca. I even reinstalled windows several times to see if it would change, I also did disable my onboard sound in the bios after installing windows twice and it doing it and I reloaded windows again and I get the same result
