Please check my post in this thread:
For me the issue is finally resolved. Everybody, let us know if this is the solution for you as well.
Have you tried different HDMI cable? I have seen problems with the NUC and a receiver and a lot case is the kind of cable used, I suggest using a high quality cable.
This solution was tested with the Intel® DN2820FYKH, you will need to try it and see if it solves your problem.
Nothing wrong with your cable, nor your NUC. Intel (so far) refuses to enable passthrough of HD (HBR) audio - DTS-HD:MA, Dolby TrueHD - via hdmi on all the celeron NUCs under Windows, even though they are all perfectly capable. So far, the only logical reason is that its a cynical market strategy to sell more i3/i5/i7 NUCs. Its a driver limitation, intentionally left out by Intel.
The driver trick mentioned earlier in this thread works great with the older DN2820FYK(H) under Windows 8.1, but not with the newer Braswell NUCs (like your NUC5CPYH) - The GPU part of the chip has changed (the Display Audio interface is still the same), and thus the Hardware ID has changed, too - leaving you unable to force the old D34010WYK driver on it. That driver is/were for Windows 8(.1) anyway, not Windows 10.
Have a read here, and voice your need for this if you will: How to get NUC5CPYH passthrough DTS-HD, Dolby TrueHD Audio?
ivanu_intel - Please don't mislead customers and community users on this all-too-well known issue, its insulting for everyone involved.
hi pr0xzen and thanks, i saw in some forms that also i3 and i5 windows drivers doesnt support the true hd.
hope the guys from intel doing somehing about it,
do you know anyone who was able to solve this ?
if i'll downgrade to windows 8.1 with my celeron NUC5CPYH will it work ?
