There are only 2 rules in intalling drivers.
- use the driver provided by your computer manufacturer. Intel's realtek audio driver is for Intel NUC computers only. Other computers from other brands cannot use it.
- use the installer (most often setup.exe) to install your driver or else really bad things happen. It is for all DCH drivers (post 2018 drivers) for audio and video (not just Intel graphics drivers). You cannot install via device manager.

99.9% of the problems are caused by installing via device manager instead of using the installer.exe.
