Cast Only Video Not Audio Chromecast? – Troubleshoot in Minutes!

The “cast only video not audio Chromecast” issue is one of the most frequently discussed topics and luckily we got you covered.

Google Chromecast is a fantastic way to cast and stream content from your smartphone, tablet, or laptop.

When the Chromecast only casts video and not audio during a session, the situation becomes quite bothersome, when you’re unable to identify what is wrong. Let’s find out!

A number of factors can cause Chromecast to only cast video and not audio, including poor connection, device bugs or glitches, or a muted volume.

If you’re using a dongle (Google Chromecast), you need to check whether the HDMI to TV connection is intact.

So, without further ado, let’s get started troubleshooting!

How to Fix When Chromecast Only Cast Video Not Audio?

If your Chromecast is only casting video not audio, following the troubleshooting methods below will help you to fix the problem.

The entire guide takes 5 minutes to read so let’s jump right in!

1. Reset the Chromecast Connection!

If your Chromecast device is loosely connected to the TV HDMI port or wiggles, it will cause audio and casting issues with your device.

The simplest and quickest solution is to secure the connection between the Chromecast dongle and the HDMI port on the TV or monitor used. 

Here is how to reset the Chromecast connection:

1. Unplug the Chromecast dongle from your TV/monitor.
2. Wait for about 5 minutes for a complete power cycle.
3. Plug the Chromecast into a different available HDMI port.
4. Don’t forget to switch the Input Source on your TV.

Another important factor is whether or not your TV is connected to a strong WiFi network.

So, make sure that the network connection on your devices is steady and consistent before testing.

2. Verify the Volume on the Chromecast

The next step is to check and ensure that your casting device’s volume (mobile, tablet, or laptop) is not muted or set to a low level.

This is important because, during the cast session, the video and audio are coming from the transmitter device, hence when muted, no audio will start.

Increase Volume on Mobile or Tablet: 

1. Go to Settings on your mobile device.
2. Tap on the  Sound or Audio option.
3. Adjust Media and Casting audio level.

Increase Volume on Laptop or PC: 

1. Right-click on the Taskbar’s Volume Icon.
2. Choose “Open Volume Mixer” or “Open Sound Settings“.
3. Check for the Playback Devices or Output Devices section.
4. Adjust and configure the Audio Level accordingly.

Increase Volume on Smart Television: 

1. Press the Home button from the remote.
2. Navigate to the TV Settings or Menu.
3. Locate and tap on the Display & Audio option.
4. Make sure the TV is set to “TV Speakers”.
5. Adjust the TV volume accordingly.

Tip: Keep the Chromecast source device volume above 85% until you identify the culprit.

3. Reboot the Chromecast via the App

Sometimes the Chromecast device just needs a reboot, which mainly addresses software bugs and glitches.

In case you didn’t know, in the Google Home app, there is a specifically designed feature that allows you to reboot your Chromecast dongle, without unplugging it from the power.

In case you haven’t done this before, follow the steps below:

1. On your mobile, launch the “Google Home” app.
2. Tap on your device under the Media Room.
3. Click on “Settings” from the upper right corner.
4. Select and tap on “More” to access more settings.
5. Click on “Reboot” to restart the Chromecast dongle.

Note: These steps will not erase any of the Chromecast settings in the app!

4. Plug Chromecast into Wall Outlet

The Chromecast device requires a consistent power supply to function properly and send both video and audio to the payout device.

When you cast only video not audio Chromecast, then you need to test whether the issue will reoccur when the dongle is plugged in directly.

• The Chromecast dongle can be powered on via a USB cable or Power Adapter!

Simply disconnect the Chromecast device from the TV USB port and connect directly to the wall outlet for the best power efficiency.

This is the only way to exclude the possibility of your TV not powering the Chromecast, which ultimately leads to audio or video issues during the casting.

Note: For the test, plug your Chromecast dongle directly into a standalone wall outlet.

5. Refresh the Chromecast Source!

The Chromecast source is the device that you’re using to utilize the Chromecast technology, no matter if you’re using the dongle or Chromecast-enabled apps.

Sometimes the reason why only the video appears is due to a fault with the source device, typically the mobile device involved.

How to Restart Mobile or Tablet?

1. Press and hold the power button until a menu appears.
2. On the menu, select the option “Shutdown” or “Power off”.
3. Info: Shutting down and restarting a device is not the same!
4. The device should turn off before you manually power it on.

How to Restart a Laptop or a PC?

1. Tap on the “Start” button from the lower-left corner of the screen.
2. Click on the power icon that looks like a circle with a vertical line.
3. Click on the “Shutdown” option from the pop-up menu to power off.
4. Your PC or laptop will shut down so you need to manually turn it on.

Note: When your device is refreshed, re-establish the Chromecast setup and test for audio!

6. Restart the Casting Platform/App

There’s a chance the audio problem is with the media or online service that you’re using.

We know that Chromecast is possible from the Google Chrome browser, which allows us to cast absolutely anything that the browser can show, hence the issue could be in the platform.

In contrast, if you’re using a Chromecast-enabled app, the reason why no audio appears could be due to faulty data.

This is why we strongly recommend performing a clean app reinstallation, which is enough to overcome the issue.

Tip: Feel free to test casting content from another online platform!

7. Configure the *Group Delay*

When using an advanced device or a group of speakers, it can be difficult for the units to properly sync the audio at the same time which results in audio delay.

In those cases, for the first few seconds, you only see the video, when the audio suddenly attempts to catch up!

In order to prevent any existing audio delay, you need to configure the group delay:

1. On your mobile device, open the Google Home app.
2. Choose your Chromecast device under the device list.
3. Tap on the Settings Gear icon from the top-right corner.
4. Choose Audio and then go to Group Delay Correction.
5. Adjust the slider to the left or the right until the audio syncs. 

When you are done with doing the group delay adjustments, then again try to cast any video to check for the Chromecast audio.

If you are still experiencing the same issue, you will need to make some additional adjustments to the group delay.

Simply, experiment with the setting!

8. Test Chromecast on Different Devices!

Another possibility is that your Chromecast or TV port is defective, causing this audio problem, which, unfortunately, can’t be solved with troubleshooting.

To justify this theory, you need to test whether you can successfully Chromecast video and audio from or to another device.

How to Perform a Chromecast Test with Different Devices?

1. Get access to another TV, monitor, or audio receiver for testing. 
2. Disconnect the Chromecast dongle from the back panel of the TV.
3. Optional: If you have a spare smartphone, use it as a new “source”.
4. Connect the Chromecast to the new “receiver” TV or any monitor.
5. Open a Google Home app on your smartphone, tablet, or computer. 
6. Tap on the Cast icon within the app and select the new receiver.
7. Play some video content with audio and check whether it works.

Assess the results:

✅ If only video is cast but no audio, the problem is with the Chromecast dongle.

✅ If both video and audio work fine the issue is with the previous receiver or source.

9. Factory Reset the Chromecast

If you’ve tried everything and your Chromecast still only casts video and not audio, the next step would be the factory reset process.

This is one of the most-effective methods since it will reset your Chromecast to default settings, and erase all in-app configurations to be able to start fresh.

Here is how to factory reset the Chromecast device in easy steps:

1. On your mobile, open the Google Home app. 
2. Select your Chromecast device from the list. 
3. Click on the Settings gear icon from the top right.
4. Tap on the three dots from the top-right corner.
5. Tap on the Factory reset and choose “Reset”.

Note: If the audio issue continues, then contact professionals for Chromecast Help!

Specific Chromecast Audio Issues for Android and iOS?

There are some specific situations where the audio of your Chromecast would not work due to operating system-specific features.

This is why let’s check both occasions – iOS and Android:

• Cast Only Video not Audio Chromecast iPhone?

If you’re using an Apple device, the audio might not appear because your iPhone is muted.

All Apple devices have a physical “Mute” switch on the device’s panel, that ultimately stops all sound output on your device. The switch can be moved sideways, respectively ON and OFF.

• Cast Only Video not Audio Chromecast Android?

If you’re using an Android mobile, and the audio of your Chromecast session is gone, it’s likely that the device is muted from the volume settings.

To adjust the audio instantly, press any of the device’s volume buttons, then ensure that the device is not muted by pressing the bell icon.

Quick Recap:

If your device cast only video not audio Chromecast, check the Chromecast connection, increase the device media volume, and reboot the entire setup.

In case that doesn’t work plug the device into a different TV HDMI port or factory reset your Chromecast dongle!
