Are you frustrated because your Chromecast is only casting audio, leaving your TV screen blank and silent? You’re not alone. This issue is more common than you think, and there are several reasons why it might be happening. In this article, we’ll delve into the possible causes and solutions to get your Chromecast casting both video and audio in no time.
Understanding How Chromecast Works
Before we dive into the troubleshooting process, it’s essential to understand how Chromecast works. Chromecast is a digital media player developed by Google that allows you to stream content from your devices to your TV. It’s a simple, plug-and-play device that connects to your TV’s HDMI port.
Chromecast uses a technology called Google Cast, which enables your device (smartphone, tablet, or laptop) to “cast” content to your TV. This content can be in the form of videos, music, photos, or even games. The casting process involves three primary components:
- The Chromecast device: This is the device that plugs into your TV’s HDMI port.
- The casting device: This is the device (smartphone, tablet, or laptop) that you’re using to send content to your TV.
- The internet connection: A stable internet connection is required for the casting process to work seamlessly.
Possible Reasons for Audio-Only Casting
Now that we’ve covered the basics of how Chromecast works, let’s explore the possible reasons why your Chromecast might be only casting audio:
Incompatible Content
One of the most common reasons for audio-only casting is incompatible content. Not all content is optimized for Chromecast, and some videos or apps might not support video casting. If you’re trying to cast content that’s not compatible, you might only see a blank screen with audio playing in the background.
Check the app or website’s Chromecast support: Ensure that the app or website you’re using to cast content supports Chromecast. You can usually find this information in the app’s settings or on the website’s support page.
Outdated Chromecast Firmware
An outdated Chromecast firmware can cause a range of issues, including audio-only casting. Google regularly releases firmware updates to improve Chromecast’s performance and fix bugs. If your Chromecast is running an outdated firmware, it might not be able to cast video content properly.

Why is my Chromecast only casting audio?
Chromecast devices are designed to cast both audio and video from your device to your TV. If your Chromecast is only casting audio, it may be due to a hardware or software issue. In most cases, it’s a simple fix that can be resolved by restarting your Chromecast or checking the HDMI connection. However, if the issue persists, it could be a problem with the video output settings or a conflict with other devices connected to your TV.
Troubleshooting steps should start with the basics, such as checking the HDMI connection and ensuring that the Chromecast is properly plugged in. You should also try restarting the Chromecast and the device you’re using to cast from. If the issue still persists, try resetting the Chromecast to its factory settings or checking for any software updates.
Is my TV compatible with Chromecast?
Chromecast is designed to work with most modern TVs, but compatibility issues can still arise. If your TV is not compatible with Chromecast, it may only cast audio or not work at all. Check your TV’s documentation or manufacturer’s website to ensure that it supports Chromecast.
If your TV is compatible, but you’re still experiencing issues, try checking the TV’s settings to ensure that the HDMI input is set to the correct mode. You may also need to adjust the TV’s audio output settings to ensure that it’s set to receive audio from the Chromecast. If you’re still having trouble, consider resetting the TV’s settings to their default values.
What if I’m using a streaming service?
If you’re using a streaming service like Netflix or Hulu, the issue may be related to the service itself rather than the Chromecast. Try casting from a different app or service to see if the issue persists. If it does, the problem may be with your Chromecast or TV.
If the issue only occurs with a specific streaming service, try restarting the app or checking for any updates. You may also need to check the service’s settings to ensure that it’s set to output video correctly. In some cases, you may need to reset the streaming service’s app data or reinstall the app altogether.
Can I use Chromecast with an older TV?
While Chromecast is designed to work with modern TVs, it can still work with older TVs that have an available HDMI input. However, older TVs may not support all the features of Chromecast, such as 4K resolution or HDR.

You may also need to adjust the TV’s settings to ensure that it’s set to receive the correct video signal from the Chromecast. Keep in mind that older TVs may not have the same level of compatibility as newer TVs, so you may experience some limitations.
What if I’m using a Chromecast Ultra?
The Chromecast Ultra is designed to support 4K resolution and HDR, but it may still have compatibility issues with certain TVs. If you’re using a Chromecast Ultra and only getting audio, try checking the TV’s documentation or manufacturer’s website to ensure that it supports 4K resolution and HDR.
If your TV supports 4K and HDR, try adjusting the Chromecast Ultra’s settings to ensure that it’s set to output video at the correct resolution. You may also need to check the TV’s settings to ensure that it’s set to receive the correct video signal from the Chromecast Ultra.
Is the issue related to my internet connection?
A slow or unstable internet connection can cause issues with Chromecast, including only casting audio. Try checking your internet connection speed to ensure that it’s fast enough to support streaming video. You may also need to restart your router or modem to ensure that your internet connection is stable.

What if I’ve tried everything and it still doesn’t work?
If you’ve tried all the troubleshooting steps and your Chromecast is still only casting audio, it may be a hardware issue with the Chromecast itself. In this case, you may need to contact Google support for further assistance or consider replacing the Chromecast.
Before contacting Google support, try resetting the Chromecast to its factory settings and ensuring that it’s running the latest software. You may also want to try using a different HDMI input on your TV or switching to a different TV altogether. If none of these steps work, it’s likely that the Chromecast is faulty and needs to be replaced.
