Can anybody confirm that the above driver is present, installed and working please. It seems to be missing on mine. The reason this is important is that this driver controls if you are able to access HD audio when using WASAPI. Here are further details of how to check.
To check if the management engine driver is installed, follow the steps below:
Open Windows Device Manager.
Click Start on the Windows taskbar.
Right-click My Computer.
Click Manage.
Click Device Manager listed on the left pane.
The Device Manager will appear in the right pane.
Scroll down and click the + icon that appears in front of System devices to expand this section.
Scroll down and look for the entry, Intel® Management Engine Interface.
If this entry is listed, the management engine driver is installed on your computer.
If this entry isn't listed, the management engine driver is not installed and you should check with your computer or motherboard manufacturer if this driver is available for your computer or motherboard. Not all computer or motherboard manufacturers provide this driver.
