Over the Thanksgiving holiday, I purchased a new TV and new sound bar. I kept the same TiVo, it did update it to the latest software. TV = Vizio Sound bar = Vizio TiVo = Roamio OTA on the latest software, the version that requires the remote to have a back button Problem that is happening, the sound turns on in the middle of the night. Usually around 3 am. I swear I have checked all my CEC settings. I even went so far as to have the sound bar replaced. Except, it was still happening. So, last night, for the first time, I unplugged my TiVo. Today, for the first time in over a month, the sound bar was not on when I got up. What setting on my TiVo is causing the sound, but not the TV to come on during the night? Any help is appreciated!
