I have recently brought a 75" Sony X90J Tv which has built in chromecast. I recently purchased 2 x Google Nest Mini's to use as rare speakers. I have all three (Tv + 2 speakers) in my Google Home and they show in the living room. But when I try to create a speaker group I can only select the 2 x Minis and the TV is not an option to add to the group.
Long story short....how can I use these Nest Mini's as rear speakers when watching TV.....
TVs with Chromecast built-in should be able to be added to speaker groups. It might be worth contacting the TV manufacturer as well in case they're aware of any reason why it's not working for you.
