How to Calibrate the Digital Output Audio Delay
If you’ve tried resetting the audio settings, but are still finding that your TV’s sound is unsynced, you may need to calibrate it manually.
This slider will quicken or slow down your TV’s audio to match the content.
Step 1: Observe if your TV’s audio is too fast or too slow.
Step 2: Go to Expert Settings.
Step 3: Click Digital Output Audio Delay.
Step 4: Use your remote’s arrow keys to increase or decrease the value. If your TV’s audio is too fast, increase the audio delay value. If your TV’s audio is too slow, lower the audio delay value.
This may take some experimenting. We suggest slightly changing the value, then playing something to see the results.
Update Your TV’s Software
Your Samsung TV may have a pending software update, causing the lip sync to glitch.
Follow the steps below to update your TV’s software.
Step 1: Ensure your TV is connected to Wi-Fi.
Step 2: Click your remote’s Menu button.
Step 3: Scroll and select Support.
Step 4: Click on Software Update.
Step 5: Select Update Now. If your TV is already updated, you will be unable to select this option.
Step 6: Do not use, turn off, or unplug your TV while it’s updating.

How to Fix Lip Sync on LG TVs?

Resetting the AV (audio and video) settings and adjusting the external speaker settings are great ways to fix your LG TV’s audio delay.
You will need your TV remote for both of these suggestions, so make sure it’s working correctly.
Let’s get started!

Step 1: Press your remote’s Mute button (marked with an icon of a crossed-out speaker) three times.
Step 2: Select Reset AV Values.
Step 3: Once reset, play something on-screen to see the results.

Adjusting the internal speaker settings allows you to manually calibrate your TV to sync with the internal speakers.
Follow the steps below to adjust your LG TV’s internal speaker settings.
Step 1: Open your TV’s Settings.
Step 2: Click on the More Options icon marked by three dots (⋮).
Step 3: Click on Sound.
Step 4: Select AV Sync Adjustment.
Step 5: If the audio is too fast, press the Minus (-) sign. If the audio is too slow, press the Plus (+) sign.
Adjust the External Speaker Settings
If you have external speakers and found that resetting the AV settings has not fixed the audio delay, you may need to adjust the external speaker settings.
Before adjusting these settings, make sure your speaker cables are securely attached to the correct ports and are not bent or torn.
Follow the steps below to adjust the external speaker settings on your LG TV.
Step 1: Click your remote’s Smart button (marked with a house icon).
Step 2: Go to Settings.
Step 3: Select Sound.
Step 4: Click AV Sync Adjust and toggle it on.

Step 6: Use your remote’s arrow buttons to calibrate your TV’s lip sync settings. Decrease the value if the audio is too fast and increase it if the audio is too slow.
Step 7: Play something on-screen to check if the audio delay problem has been resolved. You may have to return to and calibrate the External Speaker settings several times to make sure the lip sync is just right.
Wrapping Things Up
Lip sync problems are as annoying as they are distracting, but they can be fixed.
Resetting your TV’s audio settings is a good place to start, but if that doesn’t work, try manually calibrating the audio delay yourself.
Remember to be patient and don’t hesitate to experiment with the audio settings. They can always be reset, if needed.
