NUC11i7 and HDMI-cec

[Robinaa]

Hi,

I recently received my NUC11i7 as an upgrade to an older NUC. I was using the Pulse-Eight HDMI-CEC adapter which allowed me to control the media-apps on my NUC. Looking at the board layout I was unable to find the CEC header on the NUC11 and by looking at the documentation I concluded that it is now supported by the NUC. First question: is this conclusion correct?

I looked in the BIOS and found the option 'display Power Control' as mentioned in the Technical Product Specification on page 16. After that I installed my system and updated software and BIOS. After updating to the most recent BIOS (TNTGLV57.0056) the option disappeared from the BIOS settings. At the checkbox 'HDMI CEC-control' therer is a reference to the HDMI-CEC header which is not available on my NUC11.

After booting into Windows the HDMI-CEC is not working so hope someone can help me with this.

Hi Albert,

Thank you for you reply. Hereby the answers to your questions:

1. What is the complete model of the Intel® NUC? NUC11TNBv7
2. Is there any particular reason why you did the BIOS update? I have just bought and installed Windows 10 on the NUC. After doing that I downloaded the Intel Driver & Support Assistant to make sure everything is up to date. Because of the suggestion of the software I installed the BIOS update
3. Did you make any recent hardware/software changes besides the BIOS update? New setup. Installed SSD + memory and installed a fresh copy of Windows.
4. Which Windows* version are you using? 10
5. Does the problem happen at home or in the work environment? NUC is only being used in a home environment.

I've also attached the SSU report.

Thanks in advance.

Robin

Hi Robinaa, You are very welcome, thank you very much for providing that information and the SSU report.

Since the problem started right after installing the latest BIOS version 0056, what we can try now then is to do a rollback on the BIOS version to 0054 or to 0052. 

Just to let you know, there are scenarios where there is no option to do a rollback on the BIOS version, normally that is indicated in the "Released Notes", I checked them and it seems there is no problem in doing the rollback for this specific Intel® NUC model.

So, for testing purposes, please try a BIOS recovery to version 0054 first, and then if the problem persists to version 0052, in the links below you will find the instructions on how to do the BIOS recovery and then the BIOS versions. 

Please use the "BIOS Recovery by the Power Button Menu" first, if for some reason does not work then try "BIOS Recovery by the Security Jumper":

Hi Albert,

I've tried rolling back to 0054 (confirmed by SSU) which made no difference. The specific BIOS option is still not there and the CEC isn't working either.

I tried downloading 0052 but it has been removed from the Download Center.

To reflect on your first sentence (problem started after installing BIOS 0056); I'm not sure whether everything worked before BIOS update. Only thing I can confirm is that my BIOS screen has changed and an option has disappeared.

Regards,

Robin

Are you saying this is HDMI CEC command is not in the BIOS on your TN NUC? This is BIOS 0055.

[Chris_V_Intel]

And here's what it looks like on BIOS 0056. Is the feature I put an orange box around what you're referring to @Robinaa?

[Alberto_R_Intel]

Hi Robinaa, Thank you very much for sharing those details.

We are sorry to hear that the problem persists after rolling back to BIOS version 0054.

"I'm not sure whether everything worked before BIOS update", not a problem, in the link below you will find some settings to check in the BIOS in order to work with HDMI CEC, please verify them and once you get the chance, let us know the results.

"by looking at the documentation I concluded that it is now supported by the NUC", correct, actually in the following link the Intel® NUC 11 Pro Kit NUC11TNKv7 is listed under the "Onboard CEC" tab:

Hey all,

Thanks for replying. I am seeing  the same options as @MRoss5200 and @Chris_V_Intel are posting..
However, on my initial boot (before updaten BIOS) I had an extra option which was 'display power control' with a checkbox. 

Not sure whether that setting will make a difference though.

My TV worked on my previous NUC (using a Pulse-eight adapter) but since there is no CEC-header available I need to find a different solution. Maybe to be more specific: my endgoal is using my tv-remote in Kodi.

@MRoss5200 and/or @Chris_V_Intel : do you guys use HDMI-CEC and were you able to use it without any problems?

Thanks guys for the help so far.

[Chris_V_Intel]

Thank you for clarifying @Robinaa. 

Let me do some testing and see what I found out. As you mentioned above, CEC is built into the BIOS, so you definitely don't need the pulse-eight adapter.

Let me get back to you soon.

[Chris_V_Intel]

Hi @Robinaa,

I did some testing today and it seems CEC isn't quite working as correctly.

I was able to wake the TV with the NUC, but couldn't turn off the TV when the NUC is shut down, nor can I get the TV to either wake or shut down the NUC. 

It also seemed the act the same on BIOS 0054. Is what I wrote what you're experiencing? 

[Chris10]

@Chris_V_Intel I am having the same issues with my NUC11i5PAK: waking up will turn on the TV, going to sleep or power off will not turn the TV off. This was working flawlessly with my NUC7 system. What is the ETA for a fix?

[Chris_V_Intel]

Hi @Chris10,

There wasn't an actual issue. What Robinaa wanted to do was use one controller for the TV & NUC. That's an infrared issue, not a CEC one. 

Then I wasn't able to replicate my test above, so the issue was closed. 

I'm going into the office this week, let me test again and I'll let you know what I find. 

[Chris_V_Intel]

Hey @Robinaa ,

Any update?

[Robinaa]

Hi @Chris_V_Intel,

Sorry, been a couple of busy days.. My experience looks the same. The waking up the TV and/or shutting it down is not my main problem though. It's more related to using the remote after Windows has booted (for instance in Kodi). Not sure whether you tested/tried that as well?

[Chris_V_Intel]

All good!

I'm getting asked some questions so was hoping you were still around.

Good to know you're seeing similar issues. Well, not good, but at least we're consistent.

About the remote. No, I have not tested one, but I can. I just need a couple of answers first. 

1. What is the brand/model of your TV?
2. Do you have an AVR in the mix?
3. When you say 'remote', are you referring to an RC6 remote, like below or a different remote?

[Robinaa]

Here my answers to the questions:

1. Samsung QE55Q950R

2. Only thing connected besides the NUC is my Sonos sound bar.

3. I'm referring to the default remote from my Samsung TV (Samsung One Remote)

[n_scott_pearson]

So what you are talking about is a CIR issue, not a CEC issue? That's certainly a horse of a different colour.

...S

[Robinaa]

Hi @n_scott_pearson,

I'm not trying to use the CIR on my NUC. I'm trying to get the command from my TV-remote onto my NUC. My TV is able to transfer the signal correctly since it used to work on my previous NUC when I had it combined with a Pulse-Eight Intel NUC HDMI-CEC Adapter.

[Chris_V_Intel]

Hey @Robinaa,

Thank you for the information, but I'm afraid @n_scott_pearson is correct. There's no way, that I know of, that you can control the NUC with a TV remote. However, you can control the NUC either with an RC6 or Logitech Harmony remote.

You may have to go back to pulse-eight if this feature was supported by them, but it's not in the built-in BIOS.

To be clear, do you also want the NUC to wake up your TV (if it's off) or turn off the TV when you turn off the NUC and vice versa? Or do you only want to control everything with one remote? Or both?

[Ronny_G_Intel]

Hi @Robinaa 

I am checking on pending community cases and not clear to me if this issue is resolved.

Please let us know if you still need assistance.
