Is the sound on your Vizio TV lagging? If so, you’re in good company. Consumers who watch videos from streaming platforms and streaming devices may consider purchasing a Vizio. Vizio has a wide range of adaptable tech. However, their television is having some audio problems.

Are you having sound delay problems with your Vizio TV too? In this article, I will discuss the top eight fixes to ensure that you quickly fix the Sound Delay On Vizio TV. So, let’s get on with the article.

8 Ways to Fix Vizio TV’s Audio Delay

How To Fix Sound Delay On Vizio Tv [8 Easy Fixes]

To avoid giving empty “lip service,” consider the following four strategies. The most tried and true method

Fix #1: The Soft Reboot

Without wanting to sound like a broken record, have you tried powering it off and back on again? Ask yourself if you’ve thought this through before you write off the possibility. A simple reset is often all needed to get our gadgets back in working order.

It’s possible to overburden any electronic device by having many apps run to satisfy your tastes. Even while Vizio’s CPUs pack a punch, they’re not bulletproof. Just follow these instructions:

  • Step #1: Shut off your Vizio TV.
  • Step #2: Disconnect it from the wall outlet.
  • Step #3: Wait several minutes
  • Step #4: Connect it to the Power Source.
  • Step #5: Activate it one more.
  • Step #6: Observe different channels.
  • Step #7: Listen to the audio on two or three channels.

The audio should now be in sync, but if your cable channels are functioning normally, you may also want to test out any streaming services you use on your device. It’s possible that interference or a failure in the digital handshake between devices is to blame for SmartCast connecting issues.

Fix #2: Connecting Vizio To Speakers On The Outside

If your Vizio’s audio is still out of sync after a reset, the problem likely lies in the speakers. Wireless connections might fail if the external audio system isn’t up to par with Vizio’s cutting-edge technology. These steps should help synchronize them:

  • Step #1: Using the Vizio TV’s remote, go to the Menu.
  • Step #2: Navigate to the Audio menu and locate the Lip Sync Adjustment option.
  • Step #3: Set a 0.0 to 5 range to 2.5.
  • Step #4: Remember this selection for the future.
  • Step #5: Disconnect any audio sources, including the Vizio TV. (There is no need to disconnect them from the electrical outlet.)
  • Step #6: Turn on both devices after a few minutes.

Test out your newly stored tastes by cycling through the channels. This should be sufficient to resolve the issue. However, you may adjust the range as needed. Verify the snugness of your connections if they aren’t wireless.

Fix #3: Adjust the Low Latency Mode on your TV

Low latency results from the TV needing more time to process the picture and sound. It may create a slight lag in the sound.

You can fine-tune sound after you update the hardware capabilities to produce minimal latency, making the picture fluid without needing the best acceleration. The best option is to disable low latency.

Fix #4: Change Analogue Settings

Changing your VIZIO TV’s analog audio out settings is as easy as following these steps:

  • Step #1: Use the Menu button on your VIZIO TV’s remote to access the menu.
  • Step #2: Access the audio configurations menu by selecting it.
  • Step #3: You can toggle the Analog Audio Out option between fixed and adjustable volumes.

Your VIZIO TV should now respond more immediately when using external speakers.

Fix #5: Check the Lip Sync Setting

When a speaker’s lips on the screen don’t match the voices coming from the TV, this is known as a “lip sync” error. If this happens, your film could look like a badly dubbed foreign-language film.

Most of the time, the video will lag behind the audio, but the opposite is also possible. It’s the kind of thing that, once you see it, you can’t seem to take your mind off of, so it may not be enjoyable.

In some circumstances, you can fix the problem. Thankfully, your Vizio TV lets you tweak the lip-sync settings to your liking. It’s best to disconnect and reconnect the speaker if you’re using it.

Fix #6: Follow the instructions below to turn off any digital enhancements:

  • Step #1: Use the Menu button on your VIZIO TV’s remote to access the menu.
  • Step #2: Access the audio configurations menu by selecting it.
  • Step #3: Under “Digital enhancements,” deselect “Surround Sound” by toggling the corresponding switch.
  • Step #4: Under the “Digital improvement” menu, turn off the “Dialogue enhancer” preset.
  • Step #5: In the Digital enhancements menu, disable Leveling by toggling the option to “off.”

For the vast majority of listeners, this should fix the lag in the audio.

Fix #7: Change the HDMI Ports

Faulty HMI wires could cause sound issues. To rule out this, you must disconnect all of your wirings. The connections should be as secure as feasible before you try again. You need to check all your cables for signs of wear and strain, even if nothing appears to be working.

Careful inspection of the length of each line is required to detect and prevent fraying. Whenever you find something that needs to be corrected, the only solution is to get rid of it and start over with a new one. If the cords are in good shape, try switching to a different HDMI port.

These various HDMI standards each have their dedicated ports. Using a regular HDMI connector instead of an ARC or eARC connection will cause audio issues with your soundbar or home theater system.

It’s essential to double-check that the problematic soundbar and home theater system are using the HDMI connection labeled “ARC” before continuing.

Fix #8: Unplug your TV

If the sound on your Vizio television stops working, try taking it out of the wall socket. In most cases, turning on an appliance and then unplugging its power cord will not damage the device.  If you plug the device back into the wall, it will immediately resume functioning like you had turned it on.

Disconnecting the TV from the wall outlet does not reset the device; instead, it just turns the TV off and on again as if you had used the remote control. In most cases, you can initiate a factory reset by selecting the TV’s configuration menu option or pushing a button on the remote control.

­Vizio Lip Sync Problems: How To Fix Sound Delay On Vizio Tv

How To Fix Sound Delay On Vizio Tv [8 Easy Fixes]

A technologically ambitious company like Vizio might be to blame for the audio delay. Aspirations refer to the lofty claims made by Vizio’s TruSurround HD technology.

While it delivers on its promise of providing viewers with high-quality sound, the problems it introduces are just as problematic.

Great for movies with exciting action sequences or fantastical storylines. The sound it creates is so realistic that it seems to surround the audience. However, it’s often overloaded due to the numerous customization choices it provides.

To further understand this concept, consider the expression “biting off more than you can chew.” Vizio has issued remarks addressing the need for system improvements, indicating that the company is actively engaged in developing new technologies. Here are some of the reasons that you may face issues:

Reason #1: There’s a Bug

Even the most high-tech televisions might have hiccups now and again. A tiny problem might be to blame if your Vizio TV’s sound doesn’t match the picture.

The audio will be out of sync for a while, if it’s a bug, before falling back into place. It’s possible that anything other than a bug is to blame if the audio is out of sync for a considerable amount of time.

Reason #2: HDMI Port Problems

Theoretically, you only need one HDMI cable to transmit music and video across your various devices. If it doesn’t work, one of the devices isn’t supporting the HDCP encryption used by the HDMI stream. Possible causes of out-of-sync audio include a faulty HDMI cable or connector.

Reason #3: Incorrect Audio Settings

Most televisions include audio settings that may be used to improve the sound, which is helpful because TV speakers have a reputation for being particularly terrible at creating sound. To prevent audio from being out of sync while using a Vizio tv for audio, it is essential to preset the settings right.

Reason #4: Error With The Currently Running App

Most apps can be trusted, and they have simplified people’s lives. Unfortunately, software bugs are a fact of life for apps. The audio may be out of sync on your Vizio TV if you have any third-party applications loaded. You may either update your programs to eliminate the bugs or delete them entirely.
