    The CEC bug may have been fixed with a new software update that was installed on my TS4K this morning. I did some testing and the TS4K is no longer stealing control through CEC any longer on my setup.

    There are now CEC options in the settings. All are selected on by default but I don’t know how the device’s behavior changes with each option.

    Yup, my update fixed my black screen flashing and my the power down issues.. I'm really excited about that. Would be nice if someone could break down what those 3 settings under it do

    This is great, going to put my Stream back up now.

    Ok, I am at least pleased that I can now leave the Stream hooked up to my tv. I still believe the Stream has a long way to go but I will keep it setup so I can watch for further updates.

    Yeah they sent something yesterday because they also fixed the Sony Dolby Vision issue. I wonder what else is fixed that we haven’t figured out yet?

    The CEC issue was the biggest for me. Now at least I can use it for HBO Max and to cast to the tv. What is it with the surround sound for these apps? My Roku has it for nearly every app. Hulu, Youtube and ESPN+ won't do it on the Tivo.

    I just hooked my fully updated TS4K up to the TV (TCL) I have/had my Tivo Roamio connected to and I'm having the same, or similar issue, with the TS4K remote and my ARC connected soundbar (RSR); it's bizarre.

    Here's what I've found:

    1. The TV (TCL), soundbar and Roamio remote all work/worked and played together well.
    2. I set the TS4k up with the soundbar connected and although it appeared to go through the setup fine, but once setup is complete, the TS4K remote volume and mute controls just don't work. Even while using the TS4K the TV and Roamio remotes still control volume fine. So...
    3. I disconnected the soundbar, i.e. I unplugged the soundbar, and now the TS4k remote volume and mute work again with only the TV speakers, no soundbar.
    4. Reconnect/power-up the soundbar and the TS4k remote volume and mute stop working.
    So I figure this is somehow related to the ARC/CEC issues in this thread. I tried messing with the HDMI/CEC to no avail.

    Any ideas, quick fixes?

    Thanks in advance

    How many CEC devices are you using? Once you get past a certain amount, like maybe four or five or six, strange things start happening. It's why I leave CEC off with most of my devices And only have it active on four or five devices in each of my setups.

    Thanks for your reply.

    Maybe I wasn't clear in my post but there's only 1 ARC/CEC device in the configuration, the soundbar. Here's what's currently installed and powered up:

    1. The TV (TCL)
    2. The Tivo Stream 4K
    3. The soundbar (Richsound Research (RSR) TB355) plugged into the HDMI ARC port on the TV
    4. The Tivo Roamio is powered down/unplugged

    That's it. In this configuration the TSt4k remote volume/mute doesn't work, powering the TV on/off does work. I can still control the volume/mute from the Tivo Roamio remote and the original TV remote. If I unplug the soundbar HDMI cable the TSt4k remote volume/mute on the TV built-in speakers

    Still looking for a solution and opened a case with Tivo Support

    Thanks again

    Same issue, and it was not always this way. Even with just the TV, the power works but sound Volume control does not.

    I realize this isn't the point of this thread, but can anyone tell me what CEC commands the 4k recognizes? As in, can I do more than power/play/pause with my TVs IR remote and have the commands pass through CEC to the 4k? Can I navigate the interface using arrow keys?

    I've never seen arrows over CEC implemented in any TV remote mainly because you wouldn't be able to control the TV anymore. The only way to find out for sure is to try it.

    I'm curious why you would want to use the TV remote primarily rather than the Tivo remote. All you really need to control on the TV is power, volume and input, all of which you can do from the Tivo remote.

    If the Tivo remote isn't sufficient, have you considered a universal remote?
