What is Lip Sync on Vizio TV?
A lip sync problem happens when there’s a sound delay issue as you play a video on your Vizio TV. It makes it hard to connect the facial expressions to the sound.
It’s also common after one updates Vizio SmartCast TV software. But you can solve it via the numerous solutions we’ll highlight below.
Primary Sound Issues on Vizio TVs
A couple of Watching TV with Audio Sync Issues.
The two main sound problems you’ll encounter when using your Vizio TV are as follows:
VIZIO TV Audio Out of Sync
It’s an infrequent issue and usually not so profound, but it spoils the watch experience when it happens.
Often, the problem goes away when you switch off your TV and back on again.
VIZIO TV Audio Delay
It is similar to the audio above out-of-sync problem.
But this is more serious. When there’s an audio delay, every other functionality will be okay.
However, what’s on display will be different from the audio.
This problem is more nagging than the out-of-sync issue because it’s recurrent.
How to Fix Sound Delay on Vizio TV?
Adjusting TV settings.
If you’re facing either of the above issues, don’t fret. Below are the primary diagnostic and mitigation measures of sound delay.
Switch off Digital Enhancer Settings
Vizio has some exquisite features to improve their devices’ sound output. There are three main kinds of these enhancer settings including:
- Leveling
- Digital Enhance
- Surround sound
They grant you a range of customizations to improve the listening experience.
Nonetheless, their input is counterproductive to the system’s stability.
The enhancer settings are responsible for the majority of the sound delay issues.
Therefore, switching them off means that you can handle the audio delay.
But this comes at a cost; you will not access the functionalities they deliver.
To switch them off, click the Settings button and select Audio Settings.
Next, toggle each of the digital enhancer settings from the resulting window.
Change Fixed Analog Audio Out Setting to Variable

This resolution works for those with an external sound output device on the Vizio TV. The default analog audio out setting is ‘fixed.’
Hence, when you connect an external device, such as a speaker, you must change it to ‘variable.’
Here’s how to implement this change:
- Click ‘Settings’ on your Vizio TV Remote
- Select ‘Audio Settings.’
- Choose the ‘Analog Audio Out Setting.’
- Click the toggle button to select ‘Variable’ from the ‘Fixed’ default option.
- Check if the external sound output device’s sound delay is fixed.
Power Cycle the VIZIO TV

There’s arguably no better way to solve electronic functionality issues than power cycling.
The process ensures that any bug preventing smooth device function is erased. It’s a sort of hardware reboot.
Hence, we advise you to primarily software reboot your TV before power cycling.
It will ensure that everything (hardware and software) is refreshed on power cycling. Below are the soft reboot steps:
- Click System from your Vizio TV remote
- Next, choose ‘Reset & Admin.’
- Finally, select ‘Soft Reboot.’ It’ll be a ‘Soft Power Cycle’ on some Vizio TVs. The TV will go off for the reboot and then back on again.
Next, go ahead and power cycle the TV. The power cycling process is similar for all devices.
- Primarily it involves unplugging the TV’s power supply cord from the socket. You should allow the device to stay unconnected for about two minutes.
- Next, hold the remote controller’s power button for approximately 15 seconds.
- After two minutes, plug the TV back into the socket but don’t switch it on first. Let it stay undisturbed for about a minute, then switch it on.
Tweak Lip Sync Adjustment Settings

- Next, select the ‘Lip Sync Adjustment.’ It will open up to a meter with calibrations.
