No Sound Through Chromecast. How To Fix It?

Having trouble with Chromecast audio? If you can see video casting to your TV but hear no sound, here are the most effective solutions to troubleshoot and fix the problem in 2026.

Check Volume and Mute Status

First, check the volume level on both your source device (phone, laptop, tablet) and your TV. Ensure neither is muted or set to zero. Unmute both devices and turn the volume to a reasonable level, then try casting again.

Verify HDMI and TV Audio Settings

Check that the HDMI input on your TV is correctly receiving audio. Make sure the HDMI port isn’t set to ‘Audio Out’ mode, which redirects sound to an external speaker system instead of your TV. Also verify that your TV’s internal speakers are enabled in the display settings.

Restart All Devices

Restart your Chromecast, TV, and the device you’re casting from (phone, tablet, or computer). This clears temporary glitches that often cause audio issues. Power off each device completely, wait 30 seconds, and turn them back on.

Try a Different HDMI Port

If your TV has multiple HDMI ports, disconnect your Chromecast and plug it into a different HDMI port. Some HDMI ports may not properly handle audio, so switching ports can resolve the issue.

Update Your Software

Ensure your TV firmware and Google Home app (which manages Chromecast) are up to date. Outdated software can cause compatibility issues with audio. Check for updates in your TV settings and on the Google Play Store or App Store.

Reduce Wireless Interference

Wireless interference from other devices can disrupt Chromecast’s connection. Keep your Chromecast and Wi-Fi router away from microwave ovens, cordless phones, baby monitors, and other wireless devices that operate on similar frequencies.

Factory Reset Your Chromecast

If none of the above solutions work, perform a factory reset. Press and hold the reset button on your Chromecast for about 25 seconds until the light blinks. You can also factory reset through the Google Home app by selecting your device, going to Settings, and choosing Factory Reset. Note: this will erase all data and settings from your Chromecast.
