Hi Challou,
Thanks for posting and sorry to hear that you're having an audio issue with your Chromecast. Let's check on this further.
A few questions: Is the TV connected to an external receiver, soundbar, or speakers? Is the TV on mute? Are you using an HDMI monitor? Are you casting from a phone or from a Chrome browser?
Give these steps a try:
- Check if the Chromecast is connected to the power outlet and if the TV is on the right input.
- If you're using a mobile device, press the volume buttons on the device while they're in the Google Home app. For Chromecast with Google TV: If you're casting the content, you can use your Chromecast Voice Remote to check if Chromecast is muted.
- Make sure that the TV, sound bar, and/or receiver is not muted.
- If you're using a Chromecast with a TV and a separate AVR, sound bar, or external speakers, the audio should come out of the TV unless you have an output path from the TV to the AVR, sound bar, or external speakers (Example: a digital optical out cable or HDMI Audio Return Channel (ARC) enabled). In this scenario, if the audio comes out of the TV but not the AVR, then the issue is with the TV or AVR connection and not with Chromecast.
- Connect a different device to the HDMI port. If the issue persists, it's likely not a Chromecast-specific problem.
- Use a different HDMI input.
- Unplug Chromecast and plug it back in.
- Unplug TV and plug it back in.
- Check if the no audio issue occurs from all apps or only when casting certain websites.
- Cast the same Chromecast device on a different TV (if possible).
- Perform factory reset.
Let me know how it goes.
Thanks,
Jennifer
