    To ensure proper playback on your TV, follow these tips when naming your devices:

    1. Give your speaker or display and Chromecast or Chromecast built-in devices different names and avoid using the same words in the names. This helps your speaker or display correctly understand your command and play content on the right device.

        • Naming your speaker or display "Living Room" 
        • Naming Chromecast "Family TV"
      2. OK:
        • Naming your speaker or display "Living Room Home"
        • Naming Chromecast "Living Room TV"
    2. Make sure the name is easily pronounceable.
    3. Avoid using emoji or special characters.
    4. To change the name of your devices:
      1. Open the Google Home app Google Home app.
      2. Tap your device and then Settings , and then:
        1. For speakers: Tap Name.
        2. For displays: Tap Device information and then Device name.
        3. For Chromecast: Tap Name.
      3. Delete the current name and type in a new name. Tap Save. 
  3. If the voice commands seem to stop controlling your remote devices, or you get a response saying "nothing is playing,” be more specific with your request by adding “…on <device name>” to your request. This will re-initiate media focus and allow you to better control the device.
  4. If you're not hearing the music you expect, be more specific with your request. 
  5. If you hear an error message like "I can only play audio on devices using Chromecast, or on cast-enabled TVs," try renaming your devices.
