Hi there,
I have a Sonos Arc connected to my TV using the hdmi cable into the ARC port.
I added Google Assistant during the setup process and in the Google Home app, I see "Sonos TV Control" correctly located on my living room, but when I say "Hey Google, turn on the TV" I get a response from the TV too confirm it will turn it on but it never does.
When I open the "Sonos TV Control" device in the Home app, it shows as "not responding". I have deleted and reinstalled a few times but it's still not consistently responding.
Can you help?
