Works fine on Linux, but on Windows 10 installation, I get no sound out from Speakers- Realtek High Definition Audio, regular audio out jack to 2 spk+subwoofer. Detects when speaker cable is pulled in and out and test shows green bars. When I plug in a separate headset to the USB, audio is fine.
I've installed the Soundblaster X-fi software and the Realtek. Uninstalled and re-installed. I don't know if under Sound, vdeo, and game controllers there's supposed to be a Sound Blaster device but there's not - only Intel audio + Realtek HD Audio.
Seemingly there's nothing left to fiddle with.
Ideas?
