Bolt w/ LG & Onkyo

Hi, I don't know if others have run into my same situation but I'll give it a shot. I have my Bolt connected to an Onkyo AVR and that's also connected to an LG OLED TV. Every time I turn on the Watch TV activity on my Harmony 700, something (don't know if it's the TV or Onkyo) is switching the input on the Onkyo to TV or Roku and not CBL/SAT so the TV thinks there's no input coming through. I believe I read that the TV has to turn on first for the HDMI handshake to occur but as we all know, the TiVo is always on. I've tried turning off SimpleLink on the LG and CEC on the Onkyo but this doesn't seem to help. Also, when you turn them off then you stop getting DD 5.1 on the built-in TV apps. This also seems to have gotten worse when I changed the Video settings on the Bolt to 2160 Auto. Has anyone been able to solve this problem as I've tried so many different combinations of settings that I've now lost track. Thanks!
