Troubleshooting Audio on Chromecast

There are several reasons why you could be having

There are several reasons why you could be having issues with your Chromecast’s audio, so here are a few of the possible solutions to remedy it.

1. Check Your Television’s Settings

Let’s start with some essential sound solutions to kick things off. Technology can be buggy and imperfect, but some fundamental knowledge in troubleshooting can save the day.

  1. Ensure the sound issue isn’t coming from your television by checking your volume level and testing a different device for sound output (such as a game console or a cable box).
  2. Ensure that you have enabled the speakers in your television and not external audio.
  3. Make sure you have set your audio output to ‘fixed.’

Most modern televisions have a built-in option to disable the television speakers to use a home theater or surround sound system. You can also try turning off and unplugging your television for a few minutes, as well as resetting it to factory settings from the menu. Finally, if you’re using a stereo system to power the audio side of your home theater, ensure that your audio system isn’t malfunctioning.

2. Switch HDMI Inputs and Cables

Sometimes, the HDMI port (or a component on the board) malfunctions. This issue applies to both Chromecast and your TV. In addition, your HDMI cable might be damaged either at the pins or somewhere in the line.

  1. Start by switching your Chromecast to a different HDMI port. If you have an audio signal, the TV port on the original input may be damaged.
  2. Next, try using a different HDMI cable. If you get audio using this step, the cable is either damaged at the pins or somewhere in the line.

3. Double Check Your Chromecast’s Installation

There are a few points that you have to consider checking about your Chromecast:

  • Chromecast is powered by a micro USB cable with a power adapter, and plugging it into the TV’s built-in USB port doesn’t always provide enough power for it to work correctly.
  • If you have a 4K-supported Chromecast Ultra with a dedicated AC adapter, you might want to try a different electrical outlet to rule that power source out.
  • Avoid using extension cords when possible.
  • Ensure the mini-USB connection on the Chromecast is securely fastened.
  • When powering the Chromecast by a USB port on the TV, ensure the Chromecast is not plugged into a USB Service Terminal. This particular USB input is usually labeled as such.

4. Restart Your Chromecast using the Google Home App

After you’ve made sure your device gets supplied with enough power to function correctly, you can also try to restart your device to shake up any bugs that might currently exist. To do this, follow these steps:

  1. Open the “Google Home” app on your mobile device.Select your device.
  2. Select your device.Tap the “Settings” cog in the upper ri
  3. Tap the “Settings” cog in the upper right-hand corner.Now, tap “More” to view additional set
  4. Now, tap “More” to view additional settings.
  5. Finally, tap “Reboot.”

The above steps will restart your Chromecast, and it should fix any issues with both visuals and sounds. Alternatively, you can unplug the device from its power source, thus forcing a reset.

5. Check All Audio Volumes

If lack of sound is still an issue using a Chromecast on your TV, it could be the volume level on the TV or phone/tablet.

  1. Play some sort of content with audio on your phone or tablet before checking any volume levels.
  2. Ensure that the volume is turned up on your phone for Chromecast. It may be labeled as your mirroring app instead.Check the TV volume and adjust it if at a low leve
  3. Check the TV volume and adjust it if at a low level or muted.
  4. Check the source’s volume, if applicable. Apps such as YouTube have built-in volume controls that are usually separate from the device’s volume.

6. Restart the Application or URL that Mirrors to Chromecast

Sometimes, an app gets a glitch but keeps running and misbehaves. This scenario can also include losing audio output. Here’s what to do.

If the sound problem is spawning from the application, restarting the stream will force Chromecast to reload the URL from which the device accesses the video or audio feed.

  1. Try to stop the stream from your mobile device and restart it. This forces Chromecast to reload the stream source/URL.
  2. Force close the application on your device to see if the problem is coming from the app.
  3. Restart your phone or tablet if the above steps do not solve your audio problem.

7. Check for Audio Optimization using Chrome Extensions

If you have Chrome on your Chromebook or another computer, you can use the built-in Chromecast extension to ensure audio gets optimized for sound.

  1. Tap on the extension in Chrome and select your Chromecast device.
  2. Choose “Cast this tab (optimize for audio).”

8. Factory Reset the Chromecast

Finally, you may want to attempt to factory reset your device. The primary method for resetting the device is using the Google Home app, as we already discussed.

  1. To reset your device using the app on your phone, tap on the “Device” icon inside the app and select the Chromecast device in your app.
  2. After opening your device’s “Settings” menu, click on the “triple-dotted icon” inside the settings to select the “factory reset” option.
  3. Google Home will prompt you to ensure that you want to reset your device. Once you confirm your selection, you’ll be able to completely reset your device with preferences to test the audio again.

If you’re still experiencing problems with your Chromecast after trying these solutions, and you’ve ensured it isn’t another piece of A/V equipment in your setup, the next-best step is to contact Google for a warranty replacement.


Warning! Sharing desktop to Chromecast is still in beta (and experimental)

Although we did not encounter any issues in sharing desktop screens with Chromecast, Google still marks this feature as experimental at the time of writing this guide.

Update: casting a Chrome tab, or a local media file, or the whole desktop through Chrome browser on a PC/Mac is the official features now.

What Tab Casting Works Well For

Casting a Chrome browser tab is ideal for anything that’s mostly static, such as vacation photos stashed in Dropbox, OneDrive, or Google Drive. It’s also good for viewing a website at a larger scale, or even for displaying a presentation PowerPoint online or Google Drive’s Presentation web app.

What it doesn’t work as well for is video. Well, kind of. If you are using something that already supports casting, like YouTube, it works just fine because the Chromecast can grab YouTube directly from the internet, and your tab becomes a remote control for YouTube on the TV. In other words, it's no longer broadcasting its tab to the Chromecast.

Non-Chromecast supporting content, like Vimeo and Amazon Prime Video, is a little more problematic. In this case, you're streaming content directly from your browser tab to your television. To be honest, this doesn’t work well. It’s barely watchable, because you have to expect short stutters and skips as part of the bargain.

It’s easy for Vimeo fans to fix this. Instead of casting from a PC tab, use the service’s mobile apps for Android and iOS, which do support Chromecast. Amazon Prime Video doesn't currently support Chromecast, however, you can get Prime Video on your TV via other streaming devices like Amazon’s $40 Fire TV Stick or Roku.

What Desktop Casting Is Good For

Casting your desktop works well for static items like a slideshow of photos saved to your hard drive or a PowerPoint presentation. As with casting a tab, casting video isn’t great. If you want to play a video on your television, either hook up your PC directly via HDMI or use a service built for streaming video over your home Wi-Fi network such as Plex.

2.) Start sharing your desktop to your Chromecast

Now the fun begins.  Click the cast icon like you are going to cast something to your Chromecast. The next part is easy to miss.  You will need to click the little down arrow in the upper left hand corner of the window, then simply click the option for “cast entire screen (experimental)”.  Once you click this, you will have the option to choose which Chromecast device you want to cast your desktop to.  As soon as you choose your Chromecast, your PC’s desktop will start showing on your TV.

If you are only interested in casting your Chrome browser tab, or casting audio, choose one of the other two options.

What you can cast

You can cast the majority of web content. Sites using plug-ins like Silverlight, Quicktime and VLC aren’t supported and may result in a lack of picture or sound.

Audio Problems and Chromecast

Like most technology, Google’s Chromecast has its issues, including occasional hiccups and glitches when streaming media. The old ‘Chromecast Audio’ devices also experience glitches and sound problems. Typically, most of these issues can be fixed by simply turning your device off and on or by changing the USB port powering the device. Of course, problems can often have all sorts of causes and fixes, so keep trying our solutions above until you’ve solved yours. You can do a lot with your Chromecast once you get it working correctly.
