How to Fix It When a Chromecast's Sound Is Not Working

Troubleshooting no audio on Chromecast

If your Chromecast audio cuts out intermittently, there are several steps you can try to get the sound working again. And because there could be a variety of problems, we'll offer up a variety of solutions.

This troubleshooting guide covers what to do when there's no sound on your Chromecast. We recommend a different guide if there's something else going on. For example, the 'Source Not Supported' Chromecast error, or a Chromecast that keeps crashing, are different symptoms and require a different approach.

Why Is There No Sound When I Use Chromecast?

Troubleshooting a Chromecast without sound can be difficult because the issue could rest in one of many places.

Here are the main reasons there's no sound:

  • The device is muted
  • The cable or port is bad
  • The software is outdated (or experiencing a glitch/conflict)
  • The Chromecast itself is failing

How Do I Get Sound Through Chromecast?

Like most streaming devices that plug directly into a TV, Chromecast delivers sound through HDMI. As long as an HDMI cable attaches it to the display, it will carry video and sound.

This troubleshooting guide applies to Chromecasts that deliver audio and video, not Chromecast Audio or devices with Chromecast built-in. However, if you have one of those other devices, you might still find some of these ideas helpful.

How to Fix Chromecast Sound Not Working

Before you buy a new Chromecast or opt for an alternative streaming device, walk through these simple tips to see if one of them will get the sound to work again.

  1. Turn up the sound on the device you're casting from and to. For example, if you're casting a movie from your phone to your TV, make sure both your phone's volume and your TV's volume are up.

    It might sound like an obvious step, but even if the TV's volume is maxed out, you may have turned down the Chromecast's volume from your phone without realizing it. To test this, first, open the app you're trying to cast from, and then use the volume buttons to turn it up.

  2. Switch to a different input on your TV (i.e., not the one the Chromecast is using) to confirm the TV's volume works on its own. The rest of these steps will be pointless to complete if the audio issue lies with one of your other devices.

    Use the remote's Input button, or whatever that function is called on your remote, to switch to TV mode or another input with a different device plugged in (an Xbox, Roku, etc.).

  3. Completely step 2 again, but this time with the device doing the casting. For example, if you're casting from Chrome on your computer, disconnect from the Chromecast entirely, restart Chrome, and try playing audio without the cast function.

    Since you've already confirmed the volume is turned up on both the casting device and the receiving device, and the TV can provide audio apart from the Chromecast, you need to ensure the device doing the casting has working audio on its own.

    If you find it's your computer, not the Chromecast, having issues, here's how to fix your computer with no sound. Similarly, here's how to fix an iPhone with no sound and fix an Android with no sound. You might need to fix a soundbar that's not working. Regardless, if the Chromecast isn't to blame, you'll need to follow one of those other troubleshooting guides instead.

  4. Now that you know the sending and receiving devices have working sound, restart the app that's doing the casting. Whether it's Netflix or YouTube on your phone or Chrome on your computer, the sound issue could be a temporary bug that is fixed with a restart.

    Force it to close down, wait a few seconds, and then start it back up and attempt to cast it again.

  5. Restart all three devices—the phone or computer which started the cast, the TV or projector experiencing the sound issue, and the Chromecast itself.

  6. In the Home app, choose a device and tap the three-dot menu > Reboot.

    Google has instructions for how to reboot the Chromecast from the Home app, but it might be easier to unplug it for a minute.

  7. Update the Chromecast. The previous step might have triggered an update check automatically after the reboot, but if not, update the Chromecast manually.

    An outdated or buggy firmware could be to blame for the sound issue.

  8. Check for an update for the specific app causing you trouble. The app itself could be suffering from a bug that affects Chromecast's sound output.

    If an update isn't available, you could try to reinstall the app.

  9. Reset the Chromecast. It will reinstall the firmware from scratch. It's your final option to address this problem if it's software-related.

  10. Plug the Chromecast into a different HDMI port on the TV/projector. For whatever reason, there could be a particular problem with the port you're using that's conflicting with the Chromecast's or TV's ability to communicate sound.

    If an alternative port isn't the solution, verify the port works by plugging in another HDMI device. If none of your other devices work on any of the ports, but you know the devices are working correctly, then the TV is the issue here. You could verify this again by attaching the Chromecast to an entirely different TV.

  11. Contact Google. Google might be able to confirm the issue you're having is a yet unresolved software problem, or maybe you are entitled to a replacement device (assuming it's new enough).
