I use my Google home to wake and play media on my TV, and it turns on and it plays just fine. My yamaha v385 takes all the commands from the TV perfectly, but the TV seems to not select the reciever since it is in standby when Google wakes the TV. Instead, I get a video passthrough and about 10 seconds of silence, then the TV starts playing audio through its speakers. I want Google to turn on the TV in smart things, but default to the reciever instead of the TV speakers. The reciever turns on when it is selected so that is all that needs to happen but I cannot figure it out.
I have similar issue, if tv off for only couple of minutes, the sounbar will turn on AND connect with TV. In mornings, the soundbar turns on, but fails to connect to the TV (HDMI). Yes, I am connected to ARC HDMI 2 port.
