Whenever there is no sound on Chromecast, we can’t quite assume what’s wrong since there are many different factors involved.
The most important aspects are the sound of your TV and the Chromecast connection to the power and to the television.
In this guide we’re going to cover everything so let’s begin with unwrapping the solution!
When there is no sound on your Chromecast, begin by increasing the volume or unmuting your TV and/or the connected sound system.
The next step is to verify the Chromecast connection to the TV as well as the audio settings and configuration.

There is No Sound on Chromecast – Top Working Solutions!
Tip: Follow the solution in chronological order for the fastest results!
1. Volume Up or Unmute the TV
The first and most important step is to identify the way your TV and/or sound system should be outputting sound (theoretically).
If you’ve got a sound system connected to the TV, ensure to increase the volume or unmute the speakers using the provided remote control.
In addition, unmute and increase the volume of your TV as well to ensure that the audio output is not suppressed in any way. It’s also good to stay close and try to hear the slightest sounds.
In case your Chromecast still does not have sound, perhaps the best course of action would be to unplug all speakers from your TV.
Those devices include headphones, soundbars, and subwoofers as well as other speakers with connectors – HDMI, 3.5 mm AUX, and RCA.
Tip: Test whether Chromecast will output any sound with only your TV as a speaker!
2. Inspect the HDMI Connection!
The HDMI connection of the Chromecast is one of the fundamental factors which determines whether the video and audio will be working well.
In case you’ve tested your Chromecast when connected to only one HDMI, feel free to unplug the device and use another TV HDMI port.
Reminder: Don’t forget that you need to select the correct source when switching HDMI ports!
Using an HDMI Extender?
The HDMI extenders are typically performing well, but in order to close the circle of possibilities we have to remove such accessories.
The best way is to connect the Chromecast directly into the TV HDMI input and test whether the sound will be transmitted successfully.
Not HDMI Compatibility?
In case you didn’t know, very old TVs with HDMI 1.0 ro HDMI 1.2a, do not support various audio formats such as Dolby TrueHD and DTS-HD Master Audio.
This means that when streaming content with those audio formats on an old TV with old HDMI ports, the audio might not work!
Tip: Test streaming something else from your Chromecast to check the sound!
3. Soft-Reset the Google Chromecast
In case you haven’t turned on your Chromecast in a while and now there is no sound the reason might be related to the software state of the device.
By performing a reboot and a power cycle, we would encourage the Chromecast to update and refresh all operational services at once!
Here’s how to reboot and power cycle your Chromecast in easy steps:
- Open the Google Home app on your phone.
- Select the audio-problematic Chromecast.
- Tap on the three–dots and select “Reboot”.
- Power off the Chromecast using the remote.
- Unplug the Chromecast from the TV and power.
- Wait for a few minutes and test the audio.
Info: The above method will power cycle your Chromecast and would hopefully solve any visual and audio issues.
In addition, restart or re-play the mirrored content from the external device.
4. Inspect the Chromecast WiFi
One of the most important factors when speaking for audio loss on your Chromecast is the WiFi connection on both the Chromecast and your mirroring transmitter.
The general rule is that both should be connected to the same WiFi, but assuming that you see visuals, we can exclude this.
To inspect and hopefully optimize your WiFi and internet, follow the tips:
- Test the WiFi consistency and speed using your mobile
- Reconnect the Chromecast to the wireless network
- Optimize the WiFi speed by closing the device proximity
- Use the 2.4 GHz broadband of your wireless router
- Reduce bandwidth by not downloading or uploading
Using Personal Hotspot?
In addition, the Chromecast can also be connected to the personal hotspot from your mobile device.
In case of any internet-related troubles, feel free to share a hotspot and test with a reliable connection, to see whether the Chromecast sound would work.
Alert: Proceed only if you’re certain the WiFi or internet used for connecting the Chromecast is consistent!
5. Disable Chromecast “Guest Mode”
The Guest Mode on Chromecast comes with a few limitations such as Android mirroring only, no local content from guests, and a lack of mirroring capabilities.
Those limitations might have something to do with the sound loss of your Chromecast so let’s exit the Guest Mode!
- Exit Chromecast Guest Mode from the Google Home > Devices > Guest Mode OFF
Tip: When you’re ready we strongly recommend, rebooting your Chromecast and test checking whether the sound output is back.
6. Factory Reset the Chromecast!
In case nothing from the previous solutions worked, perhaps the factory restoration would be the only way to bring back the Chromecast sound.
However, this method comes with a bold downside, which is that all data and settings on your device will be permanently erased.
Here’s how to factory reset your Chromecast in easy steps:
- Ensure that the Chromecast is plugged into the TV.
- Check whether the device is powered on and connected.
- Press and hold the button on the back of the Chromecast.
- Hold until the LED on the Chromecast blinks in yellow.
- Release the button and wait 3-4 minutes for the reset.
Info: Sometimes the reset might last up to 10 minutes so remain patient until the Chromecast restarts and you see the “welcome” screen on your TV.
No Sound on Laptop with Chromecast?
In case you’re attempting to mirror the screen of your Laptop to the TV using Chromecast, well, there are quite a few things that could go wrong.
First, it’s important to ensure that your laptop’s volume is increased so the audio output appears through the TV speakers or system.
- On your Windows laptop, click on the Speakers Icon (taskbar).
- On an iOS laptop, click on the Speaker icon at the top.
- Drag the slider to the right to increase the volume < 80%.
- Then open the Google Chrome browser and go to Settings.
- From there select the “Cast” option to mirror to Chromecast.
Info: In addition, it’s extremely important to ensure that the content mirrored (the content player) audio is also increased.
The content player audio is always available when streaming a movie or TV show on the bottom when you move your cursor.
Hence, the reason why there is no sound on Chromecast is that the TV or audio system is muted or the volume is lowered.
In addition, the HDMI connection to the TV and HDMI port has to be secured as well as any misconfiguration in the audio settings.
