Intel Display Audio and Hyper-V

[EGome3]

A week ago I setup a new machine with a Gigabyte GA-Z97-HD3 motherboard and a Intel i5-4590 processor running Windows 10 Pro. I have all of the latest Intel drivers for video and the hdmi audio driver. I use the machine for a media server connected to my Samsung TV via HDMI. I had been having trouble with the Audio not working over HDMI. I had uninstalled and reinstalled the video/hdmi drivers many times with no change. I have a spare Nvidia graphics card that has HDMI audio that I tried and this card and the audio works fine. After some research and trial and error I uninstalled Hyper-V and the Intel HDMI audio worked fine after that. Are there any beta intel Display/Audio drives to try to see if they will work in Hyper-V on Windows 10? And just to confirm I had tried the latest driver from Intel as well as the motherboard manufacture. I had even tried an older Intel HDMI audio driver but that did not change the results when Hyper-V was installed.

Thank You.

Hi Hazar

I have the same problem as you and the workaround of disabling VT-d does work. My question is that will the workaround of disabling VT-d affect the Hyper-V performance? Is there any new updates from MS or Intel now?
