    Intel® Display Audio Driver gone after Windows cumulative update


      Hello everybody,


      After the recent Windows cumulative update (Win 8.1 and 10), the Intel® Display Audio has completely disappeared from Device Manager - Sound Video and Game controllers. Because of this the sound is not transmitted anymore trough the HDMI.

      This happened on my Thinkpad T430 with Windows 10 and Intel HD 4000 but also on my friend`s laptop, Thinkpad T430s with Windows 8.1 and Intel HD 4000.

      I tried re-installing the latest graphics drivers, sound drivers, roll black to older versions, flash the latest bios, but no success. The device is not seen anymore by the plug and play. I also tried to add the display audio driver manually but also no success.

      I don't know if this is an issue of the driver for the Intel HD 4000 or if a new Windows update will fix it.
