Switch HDMI Port

Switching the HDMI port is something you need to do when a sound mismatch occurs on your Vizio TV.

Problems with the HDMI port or faulty HDMI cable may cause issues like sound delay.

To see if the problem has something to do with the HDMI port or cable, you may connect the HDMI cable to a different HDMI port. Most new Vizio TV comes with multiple HDMI ports.

Similarly, replace the HDMI cable with another one and see if the issue persists.

Connect A Different Speaker

If your speaker is not working correctly, problems like sound delay can occur. If you have connected an external speaker to your Vizio TV, you may need to double-check to ensure it is working without any problem.

Most Vizio TV comes with built-in speakers, but people tend to connect external speakers to improve the sound quality and experience digital surroundings.

To see if the problem is with the speaker connected to your Vizio TV, start by removing the speaker and using the Vizio TV speaker to play some content.

If there is no delay when the sound is played through the Vizio TV inbuilt speaker, it means the issue is with the external speaker or soundbar.

You are also advised to use different aux cables to connect the sound bar or speaker to Vizio TV and check again. Sometimes, a faulty aux cable can be the reason why audio delay pops up.
