    You'll have to run cmake from platform/build again and share the error.

    I simply dont want my receiver being turned on and off several times a day. Like my Tivo , I leave my electronics on 24/7. Like a light bulb, most electronics break when powering up or down

    The best way to make HDMI-CEC work correctly is to put some of the HDMI adapters that simply don't pass pin 13 (CEC) on everything (or at least everything that doesn't have a working option to turn off CEC), then use a harmony remote to actually turn on and off the stuff you really want working at any given moment. CEC was carefully engineered by teams of experts to always do the wrong thing :).

    It sounds like you have much better knowledge of CEC than I do. I have a Mini VOX, HDMI to an older 1080p Sony TV. I have Sony's CEC disabled. When finished with the Mini, I put it into Standby. If I power off the TV at that time, the Mini never enters Standby. If I wait for the Mini to enter Standby, then turn off the TV, it's happy. Turning on the TV does not wake up the Mini. I also have an A93 Mini with Encore on that TV and it doesn't care if I power off the TV. Is this CEC related?

    Actually, the original design and implementation of CEC was pretty decent. The mistake was making it public domain, and opening up the specification to any stupid thing any manufacturer wanted to include. And there are some seriously stupid manufacturers out there.

    There are very few implementations any more that adhere strictly to the original spec. Most manufacturers either drop portions that don't interest them, or more likely, change parameters and sometimes add endless crap that doesn't work universally to try to lock people into buying a single a brand.

    The one constant in the CEC universe is that if you call a manufacturer's tech support to ask or complain about CEC matters, you will get this stock answer (because they've tortured the spec beyond recognition): "CEC works fine if all the connected components come from us! Otherwise, we can't guarantee anything about it."

    I run a Roamio Pro, a Denon AVR, a Samsung UHD player, an Amazon Fire streaming box, and an LG OLED TV, and just for giggles I tried turning CEC on everywhere to see what would happen, and as expected, I got random pieces turning on and off, and inputs on the Denon and the LG randomly changing because they all have their own CEC implementations and 'extensions' that work poorly with other brands, deliberately.

    I turned it off on everything. I use a 100% reliable switching power strip to power everything when I turn on the TV, and a harmony remote to switch sources as needed.

    Thought I had read somewhere in recent months that CEC was finally coming to TiVo? TiVo is the only device I own that can't turn the TV on and switch to the correct input when I push a button on the remote. While I can certainly do what I need to in order to switch over to TiVo, it would be so much easier if TiVo could manage this. My primary devices for watching TV are my TiVo (for OTA & select apps) and FireTV for everything else. I have added a FireTV Recast DVR on my system, so at least guests can simply pick up the FireTV remote and watch most everything from local channels, to recordings, Directv Now streaming, Hulu, Netflix, Amazon Prime, etc. And it's all controlled by one simple remote through one interface. Only issue is I wish the TiVo could play a bit more nicely with everything as it's still the superior DVR experience.

    CEC was included in the last TE4 update.

    TiVo CEC is a little green at the moment:
    - can cause audio to be silent when switching back to TiVo from another source - toggle TiVO PCM / Dobly setting to restore audio.
    - sends CEC Mute, even with no TV or AVR programmed - so if you program your TV or AVR, mutes will likely be doubled up and not work.
    - sends CEC Vol Up/Down pulses - one per button push, so it can also make programmed TV/AVR volume control a little funky. With no TV or AVR programmed, the volume is one push at a time and not so convenient.

    It does power on everything with the push of the TiVo button and selects the proper AVR input which is nice, but the other issues outweigh that for me. Looking forward to an update.

    Are you running TE4/Hydra?

    Didn't realize it went live.
    I'm still not on Hydra, and was waiting for this to take the plunge.
    Have they given any clue if and when this will also be coming to the mini?

    Thanks,

    Another good reason to never go to Hydra. CEC is specifically designed to always do the wrong thing :).

    CEC doesn't work on Tivo. Never could get it to work.

    Did you follow the link that I supplied to the TiVo article on it? That shows how to enable it on your TiVo.

    I don't believe so and the article I linked to indicates the following:

    Note: TiVo Mini VOX and Mini are not compatible.

    You can't blame CEC on Hydra, it's sins predate the interface.

    Flipped the switch under settings/remote and CEC is working to turn on TV and switch inputs now. So far haven’t noticed any problems. It simplifies things! Hope they bring it to Mini as well.

    Went ahead and upgraded to hydra - 1 Roamio box, and 3 minis.
    So far, so good I must say.
    The Roamio behaves as I'd expect. I can press the TiVo button to turn the TV on, or automatically switch to its input.
    I'd read some folks were getting issues with the mute button also causing an input switch, but I haven't ran into that. Perhaps because my remote is controlling the sound bar volume and not the TV's?
    Either way, I like Hydra just fine. I think reading all the mostly negative feedback had me bracing for the worst, but it's not too bad.
