HDMI-CEC is not working with Apple TV 4K

K,

Does controlling the TV volume with the Apple TV remote work too?

Ever since I upgraded to the TVOS 14 my CEC stopped working. Exact same cables exact same tv and nothing. I even checked for a newer update and there was one but yet it still doesn’t work. I am currently on 14.0.2 and it’s been happening ever since I upgraded to 14

Hmmm. You could be on to something. I am currently on running beta versions on both my AppleTVs, but that was the case also on tvOS 13 without it interfering with CEC functionality. I will try to remove it and wait for the next official update.

DId you try to disable AirPlay, like someone suggested earlier? I haven't had time to try that yet, but will report back on whether it makes a difference.

AT4K’s CEC has always been broken with my TV LG Oled C9. I turned off all CEC features on Apple TV. But still when I change input on my TV to my Receiver it triggers AT4K to power on and changes to its input on my receiver.

so annoying.

Apple TV goes to Denon AVR and to LG TV.

Thank you, I tried to disable airplay, but the problem remains.

However, when I connected Apple-TV to my LG OLED TV (C9) the CEC works.

But this is not the configuration I want. I want to connect Apple-TV to my Onkyo NR-656 receiver.

My preferred configuration ( Apple-TV->Onkyo->LG OLED ) worked well with CEC until recently.

I’m experiencing EXACTLY what you’re experiencing. A lot of people having issues with CEC using their TV Remote. I honestly prefer using the Siri Remote. When I wake the Apple TV, my Sony TV wakes as well. But when I put the Apple TV to sleep, the TV does NOT go to sleep. This has worked flawlessly for years and such an inconvenience having to break out the Sony Remote now. I’m glad I’m not the only one having the issue and I hope it gets addressed in the next update.

I have this problem too. I have an Apple TV 4K running tvOS 14.4. I have a Sony X900E running latest software and Disabling CEC and re-enabling on the TV does not fix this problem, nor does toggling CEC on the ATV. I have power cycled, connected HDMI cables in order, and I still have this problem.

The ATV will wake up the TV, but when I go to sleep the ATV the TV flickers to black then shows "No Signal". Not sure where to go from here. I don't have another TV to test this on.

Same issue here, I have the Apple TV 4K connected to a Yamaha RX-V 781 Receiver and an LG 4K TV.

Although it worked perfectly fine for a very long time now it doesn‘t any more.

I want to be able to again control the receivers volume again with the ATVs touch remote (via CEC and not via IR as a lame fallback solution).

I cannot even turn on the „Control TVs and Receivers“ setting, it‘s greyed out.

Tried all suggestions given here without any success so far... I really hope Apple fixes this issue soon with new tvOS version.

Just curious, does anyone here also use an RX-V 781 in connection with ATV4K? If yes, is it working for you? Curious as the Yamaha Receiver also recently got a firmware update.

I have similar issue - my Apple TV 4K was working perfectly with Samsung TV (I have 2 AT 4K and 2 Samsung TVs) however when I added hdmi matrix with an external source AT was powering an amp and TV in different room when disconnected I can not operate AT from Samsung remote

I have had this same problem for weeks and tried several solutions to no avail until I found this. It worked. Enjoy.

Even I have the exact same problem with my Apple TV 4K 2021. I used Amazon Fire TV 4K before and that remote controlled everything from Volume to Turning TV off/on. My TV does not specially give an option to turn CEC on/off but Amazon Fire TV successfully performed all the jobs.

But my Apple TV cannot either control the volume or turn on/off the TV. I can see the white LED blinking which would mean that the device is receiving signal but it fails to register the input. In my settings, I have enabled the control of the Home Theatre and control for the remote via HDMI but nothing happens. Therefore, I am having to sit with 2 remotes all the time. Very bad experience.

Apple I know you are reading this, please fix this issue ASAP. I have been on call with 4-5 different customer service agents, been to the service centre and none of them have a clue of what is going on. They do not even know this issue exists. I do not think they even cared to read this thread where so many of us have reported the problem. Please release the patch at the earliest, this is not as advertised during the keynote as well as on your website.

I’m having the same problem and this didn’t fix the issue. Old Apple TV with TVOS 14 works flawlessly. The issue is with my last gen Apple TV. It stopped working since the update.

Same issue with my Apple TV 4K since the tvOS 14 update. TV no longer turns on or off with CEC turned on on both the TV and Apple TV.

Hi,

can you please simplify..

1. Turn off CEC ON TV
2. Toggle on Apple TV?
3. then sleep wake?

This is my exact issue. But I have one Sony tv that’s on Android 8 and one on 9 and the 8 one works perfectly (on and off with Siri remote) even with tvOS 14. So I’m even more perplexed.
