Windows 10 64 bit

First, verify the sound is enabled in the BIOS. If that is OK, reinstall the Intel Motherboard Chipset Drivers (even if Intel says they are installed) then restart the PC and see if Windows detects the sound.

If the hardware is working OK, and the correct hardware drivers are not installed, Windows will install the generic, basic function, High Definition Audio drivers.

If the sound is still not working, either a Windows OS problem or a hardware problem with the motherboard and/or sound chip.
If its Windows, you will have to do a complete reinstall.
