Home / Chromebook / Chromecast Audio Out Of Sync? Here Is How To Fix It

Chromecast Audio Out Of Sync? Here Is How To Fix It

Last Updated on:


This article actually handles two separate issues. One, your regular Chromecast is not playing the audio in sync with the video.

Two, your Chromecast Audio multi-room setup is not in sync. Read on to find out how to fix both these out of sync issues with Chromecast.

Chromecast Video and Audio Out Of Sync

I have this happening occasionally with TV channels and it can be really annoying. If your Chromecast is playing audio and video out of sync, here are the troubleshooting steps to try:

  • Restart your Chromecast.
  • Restart the Google Home app
  • Restart your WiFi router. Try playing the video again.
  • If you are using USB power for Chromecast, try using the power adapter instead.

Netflix Audio Video Out Of Sync

If you are experiencing this issue only with the Netflix app, try disabling the sound from the app and start playing again. Touch the Dialog icon for these options.

When you start the video playback again, choose Stereo.

Multiple Chromecast Audio Setup Out of Sync

Chromecast Audio supports multi-room playback which allows you to cast the same music to all the connected speakers, all playing the same music, in sync.

When you find this set up experiencing audio sync issues, try the following troubleshooting steps:

  1. Open the Google Home app select the Chromecast Devices that are playing out of sync.
  2. Tap the Settings icon (three dots) in the top right corner.
  3. Under Advanced, tap the Group delay correction.
  4. Use the slider to make the audio play in sync.

Do you have more troubleshooting steps to add? Drop me a comment.

  1. I’ve checked all over and I can’t find any Advanced area to tap in the Google Home app when I go to the Chromecast device settings.

    Audio is about 2 minutes ahead of video right now – impossible to watch anything on the TV using Chromecast.

  2. This happens to me when casting Disney+ or HBO Max. When we cast Netflix, we can solve it by choosing “stereo” in the audio/subt. Icon, but with these other apps, we have this sound delay issue :/

    1. In Google home app
      1. Tap device settings icon
      2. Scroll down until you find nd the Advanced option
      3. Tap “Surround Sound” option
      4. Under “Surround Sound” tab there are 4 options
      a. Auto- detect
      b. AC3
      c. AC/EC3
      d. Stereo only

      Select the “Stereo Only” option, this ensures that the audio output from all the streaming apps is in “Stereo only” thus solving the audio sync issue.

  3. Try disabling Google assistant and comment if it helps. Thank you.

  4. This is happening for windows 10 as well

    POSSIBLE ‘SOLVED’??

    I’ve had similar issues with my Chromecast Audio (CCA) setup for ages. It was SOOO frustrating.

    I have one CCA in the house plugged into an amp/speaker setup via a 3.5mm -> stereo phono splitter cable, and one CCA plugged into a powered Philips Fildelio smart speaker via a 3.5mm jackplug in an outbuilding. The outbuilding gets it’s wifi from a Dovolo powerline adapter which is connected to cable in main house via ethernet cable.

    The CCA’s were always capable of playing to both sets of speakers at the same time, but were never in sync. The Fidelio was always behind. I tried and tried adjusting the delay on both CCA’s, but it never worked….. UNTIL……

    Now this may be where my solution may not suit your equipment…

    I wondered if my Philips Fidelio was the problem, and rightly enough, it was!!! As it is a smart speaker, I wondered if it was taking extra time to process the signal.

    So I swapped out the Fidelio for an old ‘dumb’ Denon stereo receiver and ‘dumb’ speakers i had in the garage. PROBLEM SOLVED. The CCA’s were playing in PERFECT harmony straight away.

    Don’t know if this will help anyone, but thought I’d post it just in case, because when they work as well as this, the CCA’s are fantastic.

    Good luck.
