How to correct group playback delay

To enjoy group playback, all the speakers or TVs in the group need to play in sync. Having the following devices in a speaker group can sometimes result in a delay:

  • Chromecast
  • Chromecast Audio
  • Chromecast with Google TV
  • Google TV Streamer (4K)
  • Speakers that work with Google Cast

If any audio is out of sync, follow the instructions below.

How to correct group playback delay

  1. Make sure your mobile device or tablet is connected to the same Wi-Fi or linked to the same account as your Chromecast, Google TV Streamer, speaker, or display.
  2. Cast music to the group that's playing out of sync.
  3. Stand between the out of sync speakers (or as close to in between as you can) and adjust their volume levels so you hear them both playing at about the same level.
  4. Open the Google Home app Google Home app.
  5. Touch and hold your device's tile.
  6. Tap Settings settings icon and then Audio and then Group delay correction.
  7. Move the slider to the left or right until the audio sounds in sync.

Note: For many devices, the inherent delay is extremely short, so group playback will be in sync without any additional adjustments. Don’t adjust the group delay correction unless you notice a consistent, significant delay. The group delay correction setting only affects group playback. This setting will have no effect when casting to a single speaker or TV. A device’s group delay correction setting will be applied to all the groups that the device is a part of. If you connect a Google streaming device to another speaker or TV, the previous group delay correction setting might be incorrect. Make sure to reset it to "0" delay again and check if additional correction is required.

Tips for group delay correction

Important: Speaker group creation is only available on a phone or tablet. This feature is not supported on the Chrome browser. However, you can still cast to a group from Chrome. Learn how to cast audio from Chrome.
