I tried several different HDMI 2.0 compliant cables just to see if the cable was the culprit but no luck. I have no issues whatsoever with my other older NUC5i7RYH outputting multichannel surround audio via my Denon AVR-S910W receiver. I tried both the latest and the previous released graphics driver, which would contain the Intel Display Audio driver, but still no luck.
For info - HDMI audio is carried on the same pins as video (it is carried in the same data stream as video during blanking periods where these signals don't carry picture information) - so cable changing won't usually sort audio problems if you have solid video (if you have sparkly video or break-up then a cable issue may well be the cause)
