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. These 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 fix to try when dealing with an audio problem with your Google Chromecast is disconnecting it and reconnecting with a different HDMI port. (This is assuming, of course, that you have a secondary HDMI port available.) Believe it or not, I have had issues with individual USB ports not working with a device, and trying a secondary USB port solved the problem.
But what if that didn’t work for you? The next thing to try is disconnecting your Google Cast app or the Google Cast extension in your Chrome browser from your Google Chromecast, and try reconnecting.
But what if you’ve tried that, too, and 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
- Open your Chrome browser, go to the Google Cast extension in the upper right-hand corner, and click on it.
- 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).”
You should now hear and see what you’re casting on your TV.
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. That could sort things out if the problem is a bug in your TV.
Is your Google Chromecast 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 the 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. But when my Chromecast is plugged directly into an HDMI port on the back of my TV, the Chromecast works without a hitch.
You can do a lot with Chromecast, once you get it working properly. Hopefully, one of these solutions has resolved the sound problem with your Chromecast device, and you can enjoy fully functioning audio and video after reading this post.
