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

Chromecast playing audio out of sync with video, or multi-room speakers drifting apart? Here’s how to fix both issues.

This article covers two separate issues. One, your Chromecast is playing audio out of sync with the video.

Two, a multi-room speaker group is out of sync. Read on to find out how to fix both of these Chromecast sync issues.

Chromecast Video and Audio Out Of Sync

This can happen occasionally, especially with live TV channels, and it’s really annoying. If your Chromecast is playing audio and video out of sync, try these troubleshooting steps:

  • Restart your Chromecast from the Google Home app, or unplug it for about 30 seconds and plug it back in.
  • Force-close and reopen the Google Home app.
  • Restart your Wi-Fi router, then try playing the video again.
  • If your Chromecast is powered by a USB port, switch to the included power adapter instead. Chromecast performs best with dedicated power.

Netflix Audio Video Out Of Sync

If this only happens with the Netflix app, try switching the audio track and starting playback again. Look for the audio or dialogue icon in the Netflix player to see your options, then choose Stereo and restart the video.

Multiple Speaker Setup Out Of Sync

Google Cast speaker groups (originally introduced with the now-discontinued Chromecast Audio, and still used by many Cast-enabled speakers today) let you play the same music on multiple speakers at once, in sync.

If a speaker group is playing out of sync, try these steps:

  1. Open the Google Home app and select the speaker group that’s playing out of sync.
  2. Tap the Settings gear icon.
  3. Tap Audio, then Group delay correction.
  4. Use the slider to nudge the audio until it plays in sync.

Note: Google discontinued Chromecast Audio in 2019 and stopped selling the classic Chromecast streaming dongles in 2024, replacing them with the Google TV Streamer. If you still own a Chromecast Audio or classic Chromecast, it will keep working, and these sync fixes still apply, but Google is no longer manufacturing new units.

    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.

    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 :/

      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.

    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.

    When casting to my smart tv via the chromcast device, through my Samsung S7 android phone, the sound is always about 30 seconds behind the picture, but through my Ipad Pro it is perfect. I Googled it and it said to go to the Google Home app, but when it is opened, it does not match what the advice is saying as there is no ‘3 dots’ in the upper right corner. Any help would be greatly appreciated, thanks.

      my google tv chromecast is *in* sync for hbonow and netflix and seemingly everything *except* the youtube app, which is horrifically out of sync.

      The youtube app barely works at all on my Roku, but i would expect that it would work on any device it would be the google one :(.
      (works fine from my laptop of course )

    The only option in the settings menu is “Feedback”, there is no “Advanced” option.

    Have you just asked ChatGPT? This looks like a hallucination…
