Sound/Playback devices show 2 items. TX-SR605 Intel Display audio (Default) and Speakers Realtek. No mention of HDMI
BIOS - latest. Audio via HDMI checked.
Windows 10. All updates.
Drivers. I have used both the Intel Driver update Utility and directly downloaded.
Hardware. HDMI audio works to the Onkyo TX-SR605 using my WD Live box. The only difference is the cable because the WD has a full size HDMI socket. I have tried using the original cable with an adapter and also a cable that was purchased specifically because it is (supposed) to work with a NUC.
I updated from windows 7 but unfortunately did not test the HDMI sound before hand! I have subsequently done a clean install of Windows 10 to no avail.
Just don't know what to do next. Any suggestions please?
