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?
