How to fix Chromecast has no sound

One common problem is when Chromecast has no sound. If you’re experiencing this frustrating issue, don’t worry. There are several fixes.

You can first try to check if other TV sources have sound. Perhaps you have a streaming device, game console, or Blu-ray player. If sound works with these devices, then something is wrong with your Chromecast but not your TV.

From there, you can try to switch HDMI ports for your Google device or to unplug and plug it back into the current one. See if it fixes the issue. If not, you can reboot your Chromecast via its settings or the Google Home app on your smartphone.

As a last resort, you can reset your Chromecast. You can do this in the same way as a reboot (via settings or Google Home).

For a more detailed troubleshooting guide, check it out below.

Step 1: Check the TV sound

Increase the volume using your TV remote and switch to another source. If you use external speakers, confirm they are correctly connected to your TV and powered on.

Check to see if there is sound. Try changing sources. Also, you can disable the external speakers (if you have them) so the sound comes from the TV. This will make it easier to figure out where the problem is.

If the sound is everywhere but still not on Chromecast, go to the next step.

Step 2: Reboot Chromecast

There are two methods how you can restart your Chromecast. The first is to simply unplug your Google device from your TV, wait 10-20 seconds and plug it back in.

You can also reboot your Chromecast using its internal settings or the Google Home app on your smartphone. Let’s look at each way:

Using Chromecast settings

  • Open Settings and go to System.
  • Then scroll down and select Restart.

Using Google Home

  • First, open the Google Home app and select your Chromecast device from the main screen to get a basic remote interface.
  • Here you can use the slider to adjust the volume.
  • If it doesn’t help, tap the gear icon at the top right corner to open Device settings.
  • Finally, tap the three dots icon at the top right corner and select Reboot.

Once you have rebooted your Chromecast, check whether the sound is working.

Step 3: Disable Dolby Digital Audio

disabling Dolby Digital audio on your Chromecast and TV can help resolve the sound issue. Here’s how you can do it.

On Chromecast

  • Go to Settings and select Display & Sound.
  • After that, navigate to Advanced sound settings and select Surround sound format selection.
  • Find the Dolby Digital and Dolby Digital Plus settings. Turn them off.

On the TV

  • Using your TV’s remote control, access the settings menu.
  • Look for the audio settings or sound options.
  • Find the Dolby Digital or Dolby Digital+ setting.
  • Turn off Dolby Digital or select a different audio format like PCM or Stereo.

Disabling Dolby Digital audio can help resolve compatibility issues between your Chromecast and TV. Some TVs may struggle to decode or process the Dolby Digital audio signal from the Chromecast, resulting in no sound. You may restore the audio functionality by switching to Stereo or another compatible audio format.

Step 4: Factory reset Chromecast

If the above steps don’t yield positive results, you may need to perform a factory reset on your Chromecast. To do this, follow these instructions:

Using Chromecast settings

  • Go to Settings and select System.
  • Then navigate to About and click Factory reset.

Using Google Home

  • Open the Google Home app and select your Chromecast device
  • Afterward, go to the Device settings by tapping the gear icon.
  • Tap the three dots icon at the top right corner and choose Factory reset.

Remember that this will erase all settings and data on the Chromecast, so be prepared to set it up again from scratch.

If you have exhausted all troubleshooting options and the problem persists, it might be time to contact Chromecast support for further assistance.

If your Chromecast is still under warranty and none of the troubleshooting steps or support suggestions have resolved the problem, you may be eligible for a replacement. Contact the manufacturer or the retailer where you purchased the device for further assistance.

Can network problems affect the sound on Chromecast?

Yes, network problems can potentially affect the sound on Chromecast. Chromecast relies on a stable network connection to stream content, including audio, from your casting device to your TV. If there are network issues, it can cause interruptions or delays in the audio playback.

Verify that your Wi-Fi network works correctly by testing it with other devices. If you suspect Wi-Fi problems, try moving your router closer to the Chromecast or use a Wi-Fi extender to improve signal strength.
