Add chromecast tv to speaker group. Group any combination of Google smart speakers and displays, Google streaming devices, and Google Pixel Tablets together for synchronous media throughout the home. I made a Speaker Group called "Cinema Mode" with (i & ii) and I can play Spotify on that group by using voice Commands through the Google Home Mini. Google Home functions flawlessly as a speaker with all devices, provided they are connected to Chromecast. The support article clearly states that Chromecast with Google TV is supported in speaker groups. Use a voice command to start playing media on a speaker group. Most did it a long time ago but we're still hearing reports of manufacturers that are way behind in updates. 31 votes, 17 comments. Find the speaker you want to add to a group and tap on the three vertical dots in the top right-hand corner of the device's on-screen card. If your device isn't showing, contact the manufacturer to see if they have the update scheduled. You can create pre-set speaker groups that you use often or use the mini-player to add, remove or move speakers when playing media. nniupre wezaifu xrooptj jpcfi osl sgzrt oro adhyb lxlw bju
