Recently upgraded to Windows 10, installed drivers using the Gigabyte tool. Everything seems fine, except that the stereo mix option in recording devices doesn't seem to work. Its present and enabled, but will not seem to pick up any audio under any circumstances. If it matters, I have a USB headset. The same hardware configuration setup was working in Win 7, so I suspect this is just a driver issue, so I've tried downloading and installing manually, but no luck. Any suggestions?
