Thank you for joining the Intel® NUC.
I would like to double check some information from your description, please see below;
- Have you made any recent hardware or software changes?
- What is the behavior if you only use the built-in IR?
- What is the model of the ITECIR Infrared Receiver you have?
- Try to disable the built-in IR from your BIOS configuration, and then test the ITECIR Infrared Receiver.
Amy, there were no hardware or software changes. The ITECIR is the builtin IR that Intel uses. I have not tried an external IR receiver yet but that defeats the purpose of having a builtin one.
I tried to reproduce this on a NUC7i3BNK (BIOS BN0042 then BN0045), a NUC7i7BNH (BIOS BN0042 then BN0045) and on a NUC6CAYH (BIOS AY0038). In all cases, if I wake the system from S5 using the Power Button on my RC6-compliant Remote Control, the ITE CIR device is (still) seen and is (still) exposed in Device Manager. It did not disappear as a result of this wake method.
Are you running on the latest BIOS and drivers? If not, I suggest you upgrade and then test this again.
P.S. Unfortunately, I am not set up to test whether a CEC-based wake will act the same.

The IR driver is 18.104.22.168 which is the most current listed on the Intel website.
BIOS was 42 on both units but I just noticed the two new versions and updated to 46 on one system with no change to this issue.
Both NUC's are running 8GB RAM,Samsung 950 PRO NVME and Windows 10 1703. NUC 2 was originally on Windows 10 1607 but this issue was present before the upgrade to 1703.
The way the units are connected:
NUC 1 HDMI to Denon AVR-S700W HDMI to Samsung UN65JU6500 TV
NUC 2 HDMI to Denon AVR-4520CI HDMI to Epson 5040UB projector
When I power on I turn on the TV or projector which turns on the Denon receiver and NUC and IR does not work.
Rebooting the NUC from within Windows fixes the IR.
Powering off the TV or projector turns off the Denon receiver and NUC.
I have tried NUC 1 without the Denon AVR-S700W and connected directly to the Samsung UN65JU6500 TV with the same result.
Below is a picture of the BIOS settings for the TV HDMI actions.
NUC 1 powered on by turning the TV, IR is not working or present in device manager.
NUC 1 after rebooting windows, IR is working and present in device manager along with a few other things that disappeared.
Driver version of the IR Receiver.
I am trying to narrow down the options for this issue.
Would you please confirm that the issue is only exhibited when you turn the TV or projector on that turns on the Denon* receiver and NUC? Are you using a CEC (HDMI CEC Information for Intel® NUC) set up as well?
If you turn on the NUC by pressing the power button, do you experience the same issue?
Yes I am using CEC on the NUC but it is just by the HDMI cable to the Denon receiver and projector/TV, I have a screenshot above of the settings. I originally thought pushing the power button was preventing this issue but the only way I have duplicated that recently is if I use the power button to turn the NUC on after it was previously unplugged. Turning the NUC on by CEC, IR or the power button when the NUC has been shut down by CEC or windows is preventing the IR from showing up in windows until I reboot. The exception seems to be booting the NUC after its power cord has been removed.
JSchuricht, thank you very much for your patience.
We have been reviewing this matter and at this stage we have a suggestion that worked for us, please find it below.
After installing the latest HDMI firmware the problem was resolved on our systems, please give it a try: Download HDMI 2.0 Firmware Update Tool for Intel® NUC Kit NUC7i3BN, NUC7i5BN, NUC7i7BN, NUC6CAY
I already have that firmware installed but will reflash it and see what happens.
Reflashing the firmware made no difference.
