I have a Sony 75XBR850C (2015 model). I have had NO success getting it to work with Google Home.
When I give it commands to play music or youtube on "TV", it says ok, but nothing is happening.
When I give it commands to turn TV On or Off. It says it can't do that yet.
I watched videos on YouTube of people doing the above, but I've had no luck. https://www.youtube.com/watch?v=LfnHTpS1StM
I'm on version 1.23 of the Google Cast on the Sony. I've also followed all the suggestions here as well: https://productforums.google.com/forum/#!msg/googlehome/OcgiCHo113k/TzI2zM1IBwAJ
This includes
1)removing update, reapplying update.
2)clearing cache and data
3)removing and relinking the TV
Any other suggestions or help?
I have gotten it to play a YouTube video before, but not Netflix or Google Play music.
Try using the Google Home app on your phone/tablet and making sure your TV is given a name. In my case I said "Play my recommended videos on Sony TV" and it did what the video suggested.
