In summary, if you’re facing the issue of no sound through HDMI on your Vizio TV, here are the key points to know:
- Check HDMI Cable: Ensure your HDMI cable is properly connected and not damaged. Re-seating or replacing the cable can resolve this issue.
- Verify Audio Settings: Check and adjust the audio settings on both your Vizio TV and the source device to make sure audio output is set to HDMI.
- Update Software and Firmware: Outdated TV software or firmware can cause sound problems. Check for updates in your TV’s system settings and install them if available.

1. HDMI Cable Connection Issues
Reason: Often, the simplest explanations are the best.
Check your HDMI cable to ensure it’s properly connected.
Sometimes, a loose or damaged cable can result in no sound.
Solution: Re-seat your HDMI cable on both ends – that means your Vizio TV and the source device.
If you suspect your cable is damaged, try a replacement cable to see if that resolves the issue.
2. Audio Settings Misconfiguration
Reason: Your TV and source device have intricate audio settings that might not be correctly configured, leading to the absence of sound.
Solution: Access your TV’s audio settings via the menu and ensure that the audio output is set to HDMI.
On your source device, such as a gaming console or Blu-ray player, check its audio settings too, making sure it’s set to send audio via HDMI.
3. TV Software and Firmware Updates
Reason: Outdated software or firmware can cause various issues, including sound problems.
This is a crucial aspect of TV maintenance that’s often overlooked.
Solution: Go to your Vizio TV’s settings menu and navigate to “System.”
Check for available software or firmware updates and install them. A simple update might be the cure to your audio ailments.
4. HDCP (High-bandwidth Digital Content Protection) Issues
Reason: HDCP is a copy protection protocol used to safeguard digital content.
If there’s a mismatch or an issue with HDCP, it can lead to sound problems.
Solution: Try resetting the HDCP on your Vizio TV. Turn off both your TV and the source device, unplug the HDMI cable, then plug it back in and turn everything back on.
This can help reset the HDCP handshake and resolve any compatibility issues.
