Perhaps with that report, some of us can take a look to see what audio drivers are really installed in your system.
If you’ve got a pretty old motherboard, sometimes we need to either find new Reference drivers for your sound chipset, OR, go back and reinstall the ones that came with XP/Vista/Whatever, and perhaps set things to enable ‘unsigned drivers’. Why? Occasionally people who upgraded from XP, Vista, Windows 7, etc. had things working fine until some Windows 10 auto update (The big Annual Windows 10 Update that came down sometime in September) decided to clean out all the ‘unsigned drivers’.
I’ve had something similar happen on my older rig before…had to go through the process of enabling unsigned drivers, then reinstall quite a few of them. In my case, I needed newer reference drivers for my onboard audio chipset. I also had a bunch of older stuff that while it was properly signed for Vista, for whatever reasons, Windows 10 rejected them based on the digital signature.
Of course, all of that can be avoided by simply purchasing a modern USB Audio interface well vetted in Windows 10 and plugging it in
