How to Fix TV Sound Problems with Chromecast

Google Chromecast

Say you’ve picked up a Chromecast and are about to cast a movie or show you’ve been dying to watch. The video is up on your TV screen in all its glory, but there’s no sound—did you suddenly lose your hearing? Probably not. Sometimes things don’t always work perfectly out of the box.

This post highlights various solutions to fix sound problems with your Google Chromecast.

Sound Fix Solutions

The first and easiest route when trying to solve an audio problem with your Google Chromecast is disconnecting it and trying another HDMI port. (This is assuming you have a secondary HDMI port available.) Believe it or not, I have had issues with USB ports not working with a device, and trying a secondary USB port solved the problem.

That didn’t work for you? Disconnect your Google Cast app or the Google Cast extension in your Chrome browser from your Google Chromecast, and try reconnecting.

The sound still isn’t working? I’ve got a couple more tricks up my sleeve that may hopefully solve your sound issue.

Google Chrome Browser

  1. Open your Chrome browser, go to the Google Cast extension in the upper right-hand corner, and click on it.Chromecast Selection
  2. Click on the small arrow in the upper right-hand corner of the box where you select your Chromecast. Then click “Cast this tab (optimize for audio).”  Click Google cast arrow

You should now hear and see what you’re casting on your TV.

Other Suggestions

If you’re still in a pickle, another thing you can try is turning off the TV for a minute or two to reset everything. Is your Google Chromecast being powered by a USB port on the back or side of your TV? Plug your Chromecast directly into a wall outlet for power, instead of using the TV to power it. Turn everything back on and see if you have sound now.

You can control the volume on the Google Chromecast from your smartphone if you are using it to cast to your TV.  Make sure your volume is turned up on your device.

I know from personal experience that my Google Chromecast won’t work properly through an HDMI extender—the audio works, but the video doesn’t. When my Chromecast is plugged directly into an HDMI port on the back of my TV, the Chromecast works without a hitch.

Hopefully, one of these solutions has resolved the sound problem with your Chromecast device and you have fully functioning audio and video after reading this post.

    Unfortunately none of your Solutions work as I have tried literally every configuration possible and done all the reboot unplug plug in as required let me ask is there a box that I could plug the HDMI cable into and then have separate HDMI out and RCA jack out or something of that nature before it even gets to the television that I could plug audio into something separate

    Hi Clyde,
    I’m sorry you’re having a hard time getting sound to work. Do you have a sound system that you could connect to your television instead of the built in Tv speakers? Then, connect the Chromecast to the HDMI port of your television and sound should work. Also, make sure you’ve installed the most current version of Google Chrome browser.
