Switch HDMI Ports​

Many Vizio Smart TVs are configured with multiple HDMI ports, which can cause audio delay problems if your soundbar or home theater system is connected to the wrong port. You need to check that devices such as your speakers are connected to the ARC or eARC HDMI port.

Check the cables​

In addition, you may need to check all cables. If the cable connecting the soundbar or home theater system is damaged, or if the cable is not securely plugged into the port, this can lead to audio errors.

Turn off Low Latency Mode​

When the TV takes time to process the image and audio, which passes through several circuits before being displayed on the screen or coming out of the speakers, you have latency. This can cause a delay between what is shown and what is heard on your television.

Because of the low latency, the hardware capabilities are adjusted in such a way that the picture becomes smooth and does not use the highest acceleration, leaving room for the sound to be appropriately adjusted. Turning off low latency is your best bet.

Disable video and audio processing​

You may need to go to the sound bar menu and adjust the equalizer settings for this.

1. Navigate to presets such as sports and videos.

2. Next, select either the dialogue volume leveler and enhancers or the virtual 3D option.

3. Now turn them all off and see if your delay has been eliminated.

Update Vizio TV firmware​

Outdated TV firmware can cause errors when you use apps or stream media, and can also cause sound delays. Usually a new version of firmware is automatically pushed to your Vizio Smart TV, so if you missed the update, follow the steps below to update your software.
