So I have searched high and low to solve this problem and nothing seems to be getting it done. I have an Asus mother board and when I was on Windows 8.1 my audio worked just fine. As soon as I made the switch it stopped working. I went to Device manager and it has an exclamation point with a caution sign on my audio drive but as soon as I try to update it, it tells me that it is up to date. Anyone else having this issue? Losing sound and going crazy trying to fix it? And if it matter, I did build my computer
