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)
I realized that long ago. The problem is no audio is passing at all, not even break up or static. So I thought that the maybe a faulty or subpar cable could be limiting or stopping audio playback entirely. After trying several different cables, I verified the cable was not the source of the problem. I turned my sights and tried different sampling rates (44.1 KHz to 96 KHz) and bit ranges (16-bit and 24-bit). I also verified this changing to a lower display resolution (1080P) did not fix this. I then tried the latest display driver and previously release driver. I also verified this did not alleviate the problem. I finally tried a beta BIOS from Intel support via email. I verified that this did not solve the issue, either. I received notice today in the Intel forums that someone owns the Skull Canyon with a Pioneer receiver that 5.1 sound is working properly for them. So it is likely an issue specific to the current generation of Denon receivers, including the AVR-S910W (mine) and the AVR-X6200 (the other user's in this forum). I will soon be opening a case with Denon as well so if Denon's hardware is the problem, they can release new firmware with a fix.
