    I have my 4K Stream attached to a Samsung TV and for sound a Sonos Beam by hdmi to Samsung's hdmi/arc connection. I have the Sonos attached by hdmi rather than optical because I want to utilize the built in Alexa commands which I use in my home. To utilize the hdmi/arc input, and receive sound from the Sonos Beam, CEC/Anynet+ must be turned on in the Samsung. Unfortunately, the 4K Stream hijacks control of the Samsung and does ghostly things such as turning the tv back on, changing the input to the input of the 4K Stream even though I changed the input to something else before closing down the TV. I have even tried running the 4K Stream through an hdmi switch and tried to trick the system by programming my Harmony Remote to go to a different input when shutting down the tv. None of this has worked. And without a solution to this problem, I have to temporarily pull the 4K Stream out of my setup until this issue is fixed by Tivo. I am sort of disappointed by this. I know that Tivo is aware of this issue and hopefully will issue a hotfix soon.

    Any thoughts?

    I have the same problem and have submitted the issue to Tivo through the email support on the website. I suggest everyone who notices this issue submit a report to help them correct it. There is another thread on here on how to access developer menus in order to turn CEC off on the Tivo Stream 4K but I have not done it yet. I've just left the HDMI unplugged when not using it for now (far less than ideal)

    You're not actually holding your breath 'til CEC is solved, are you?

    It's kind of a 'Wild West' protocol with no clearly defined rules. So, every manufacturer makes their own implementation.

    It seems like there'd be a market for a 'One Device to Rule Them All', kind of device, but I've never seen it.

    A Raspberry PI has a fairly robust CEC capability. It makes me wonder if there wouldn't be a fairly straight-forward way for a RPI to 'read' the CEC Traffic and learn the proper settings and override the bad results.

    Either way, if I were you, I'd look for an existing solution.

    I'd like to think that someday CEC will mature enough where everything places nicely. I remember long ago when USB first came out for computers. Nothing worked without special drivers that were not easily obtained. For many years it was referred to as the "Useless Serial Bus" :)

    I just want the TiVo stream to stop hi-jacking my TV every time I turn it on. My TiVo Roamio is the prime viewing device in our household, it's what my wife and I are both used to and the TiVo experience has been great for us for over 20 years. An older Roku and the built in Netflix and Amazon Apps in our LG Smart TV are our other sources. The Stream 4K was to take over for the Roku for things like CBS All Access, XFinity on Demand and a few other small things.

    But the fact that TiVo Stream change the input to itself each time we turn on the TV is exceptionally annoying. I tried turning off the CEC function on TV, but then I lose control of my Sound Bar, and somehow even lose audio to my Sound Bar. So disabling CEC on the TV is off the table.

    TiVo needs to make fixing this CEC bug their first priority.

    You lose audio to your sound bar because CEC/Arc through hdmi is required for the tv to route audio to it. I agree, and I am in the exact same situation as you are, about the CEC issue

    I lose control of the sound bar. When I turned off CEC on the LG (in the hopes of defeating the input swap) it switched the audio output to a different output mode on the TV, which defeated the interaction between TV and soundbar.

    I guess CEC or some form of audio control for the soundbar works through the Fiber Optic Audio Connection I'm using.

    CEC can be turned off on the TiVo Streamer but it takes a little work. Go to the post

    HDMI-CEC has worked great for me in multiple setups. Since I started using it in 2012. The issue I've seen with HDMi-CEC is when you get past a certain number of devices, weird things start to happen. And it doesn't help when you have devices like the Stream 4K, that don't have user settings to turn it off.

    With the Stream 4K I'm trying out, I was fortunate to be able to turn off all CEC functions with my Shield TV. Because adding the Stream 4K pushed me to the point of having issues with HDMI-CEC. But once I removed that one device, the Shield TV, the Stream 4K and my other HDMi-CEC devices have been working fine.

    Although I'll probably try it in my other UHD setup which uses a Vizio speaker bar and Sony TV to see if I have issues there. I'm also at the limit of HDMI-CEC devices there, where adding another HDMI-CEC device will start to cause weird issues.

    I have a nvidia shield and it sometimes fights me from going to the Tivo Mini. However the streamer like you guys said does it almost every time. It even outfights the nvidia shield. It maybe something to do with how android tv works. Either way they should be able to fix it. Maybe they can fix the unmute on TiVo edge when CEC is enabled and pressing any key on the remote. With CEC off it doesn't unmute the tv automatically.

    Any word on them fixing this? Mine is disconnected until it's fixed.

    Unfortunately for me, disabling the CEC on the Stream turns off the hdmi controlled audio from my TV to a Sonos Beam. In order to fix that, I would need to replace the hdmi connection with an optical connection which then disables Alexa voice control on the Sonos Beam. It is a Catch-22. In the meantime, I do the same as Steveknj, I keep the 4K disconnected.

    I'm not looking to "hack" into the device to fix it. I want TiVo to fix it. I have other devices that work fine to stream what I want. I just wanted to try this one out, mostly because people were saying good things about how they sort programs. But so far there are so many issues with this device that it's an epic fail in my book. But as it's cheap enough to hang onto, I'll just keep checking here to see if some of the issues were fixed.

    Not there...
    For the time being, I'm hoping TiVo addresses this in the relative short-term. At the very least, just expose some of the CEC enable/disable functions without having to use a hack to fully disable. I had the worst case scenario since I couldn't even power down my AV system with the stream connected.

    For now, since I'm evaluating both a Fire Stick and a TiVo Stream to figure out which one will be my primary cord-cutter, I've relegated the Stream to my bedroom and the Fire Stick is connected to the receiver in the living room since it doesn't suffer the same CEC problem.

    For me the contest between Fire Stick 4K and TS4K is over. Fire Stick wins by a landslide.

    hardware wise, the Firestick is far superior at this point, with really no issues like CEC and auto turn on the TV and such; I just hate the FireTV interface and what a PITA it can be to navigate if you aren't a big Amazon video/prime Video user.

    for total superiority, though, my Nvidia shields are still far and away superior to this thing, but obviously you pay more for that superiority..

    I’m unplugging the USB cable when I’m finished with the Stream. What a pain. This issue needs to have top priority on TiVo’s fix list.
