Intel Kaby Lake Hardware
I am bitstreaming all audio to my receiver (Pioneer LX801) which handles all audio and all from 2 chanel stereo to atmos and dts-x works perfect on my setup with the same mobo as yours.
I havent flashed my mobo as hdcp 2,2 worked fine out of the box for me.

There is a bug in powerdvd 17 which i think is messing up the audio at your end.
I am not at my PC atm so i dont have the link with the solution but once applied you should be all good

Thank for the post. I tried various connection methods to test this issue after the hdcp 2.2 upgrade. Lossless audio bitstreaming works fine when I use the data port output from motherboard to HDMI on Marantz 8802a, but only PCM works when I use the HDMI output from the board. Kodi 17.6 is the player I use to playback all my video files. PowerDVD 17 is installed to test the 4k HDR files when I get my 4K Sony projector.

Ok. I use a nvidia card atm but i have tested the onboard hdmi with internal gfx and on kodi 17.6 with dsplayer 4K HDR works just fine. Not 100% sure about the audio there but i think it worked just fine as i didnt notice anything unusual.

Just a warning from me for my fellow Kaby Lake users. Do NOT update your HDMI 1.66 firmware to the latest 1.71 or 1.72 firmware from Intel. It will mess up your device and HDR won't work anymore in Windows 10. It was a pain in the #ss for me to revert back to 1.66.

Hi, I'm planning to replace my NUC 6th generation with a 7th generation Kaby Lake NUC (NUC7i3BNH) only for one reason: to be able to play 4K HEVC 10bit movies, as the 6th generation isn't capable to decode it in hardware.
Reading some reviews I saw that there are/were some problems with the HD Audio Passthrough (DTS-HD, etc) on the Kaby Lake but not sure if they were fixed and working also on Linux.
So my question would be if currently are there problems with HD Audio Passthrough on Kaby Lake + Ubuntu 16.04 + Kodi 17 ?
Thank you!

There was a problem with the Audio HD, in Leia there is a fix and it's working now, and to tell you the truth if you will use Aeon Nox 5 or similar skin (not heavy skin) the best streamer for now including 4K HDR (I'm using it) is the Minix u9-H

Great, you've opened my eyes, I was stuck on NUCs, but Minix u9-H seems exactly I want and I'll keep the current NUC for other things. Tomorrow I'll get one Smile!

 Have you actually tried?  ...the Apollo Lake (6th gen) NUCs do in fact hardware decode 4k HEVC 10bit...

Yes I've tried, and no, it doesn't work. Apollo Lake is the same generation as Kaby Lake, 6th generation is Sky Lake (as 6260U, mine)

What's about cpu decoding, my i5-haswell can do it, upto 24/30fps hevc 10bit files.

Well, mine can't do it (4k 10bit) ..Smile
