Play YouTube TV using Google Nest or Home speaker and display and Chromecast

Note: The following steps are optional. If you have multiple Chromecast devices and TVs, you can follow these steps to link all your devices and choose a default TV when playing videos from your speaker or display.

1. Make sure your Chromecast or Chromecast-enabled TV is set up and connected to the same Wi-Fi as your mobile device or tablet and speaker or display.
2. Open the Google Home app .
3. At the top right, tap your account.
4. Verify that the Google Account shown is the one linked to your Google Home or Google Nest device. To switch accounts, tap another account or Add another account.
5. Go back to the home screen, then tap Settings .
6. Scroll down to "Google Assistant services," then tap More settings.
7. Tap Devices   Add...
8. The Google Home app will search for remote devices on the same Wi-Fi network as your speaker or display. Note: You may see a list of devices that aren’t voice-supported. These can’t currently be linked to your speaker or display, but they'll be available soon.
9. To add a device, tap the check next to the device name. You can select multiple devices. Tap Add.
10. You'll see linked remote devices TVs and speakers section of the Google Home app.

Note: If you get an "Error when linking device" error message, you must factory reset your Chromecast device.

If your device is having trouble with accuracy, try being more specific. For example, try saying the entire name of a program, the service (e.g., "...on YouTube TV"), or the name of your device, (e.g., "...on Chromecast").

When you start playing a TV show or movie using your voice, like "Ok Google. Watch This Is Us," all of your next control commands (pause, next, etc.) will control that TV. You won't need to specify the TV after the viewing session begins.

If you're casting to a TV from your phone or tablet, you’ll need to say "on [device name]" (e.g., "Pause the Warriors game on the living room TV"). After you specify the device the first time, you won’t need to say "on the living room TV" again. 

When media is playing on Nest or Home device at the same time as your remote device, all control commands will control your speaker or display, not your remote devices. To control your remote device, you have to always say, "Ok Google, [do X] on [device]."

If you want to stop playing content on your speaker or display, say "Ok Google, stop." If you want to start controlling the remote device that is playing, you must first say "on [device]" to the next command you make to this remote device. For example: "Ok Google, next video on TV."
