Does this means that there is a risk of it not working? Certainly. They are not going to release the package for a board on which it has not being formally tested. Why? Because the package has only been verified by Intel with the active NUC products. Yes, you are indeed downloading from a NUC link. I did this using Windows 7, but the package says it supports Windows 8.1 and Windows 10 as well, so should be ok. I believe that the codecs on the other 8-Series Desktop Boards should be supported as well. I have verified that the codec on my DZ87KLT-75K is supported. The Realtek driver packages are cumulative and include support for many other Realtek audio codecs. What else should I check on my end to make sure it is simply not a misconfiguration by me? Has anyone else had a similar issue and managed to resolve it? (this is newer than the latest version listed on Intel's site by a significant margin and appeared to ship with Windows 10). Windows and the Realtek software simply do not have support for HDMI audio for some reason. I am able to have audio sent via the analogue jacks and the optical jack just fine. To be more precise, I am able to view an image via HDMI and this is my primary video output (TV).
I went to the Intel Download Center and made sure I was using the latest available drivers and upgraded my BIOS just now to the latest revision but still no success. This was working perfectly in Windows 7 but upon me upgrading to Windows 10 there appeared to be no drivers for a High Definition Audio Device in my Device manager list. Unfortunately, I have been unable to succeed trying to configure HDMI audio since the upgrade. I have recently upgraded my media PC to Windows 10 Professional 圆4 from Windows 7 Professional 圆4 and the process was fairly smooth.
