Please continue reading to learn more about why your Insignia smart TV lip sync is not working and how you can fix it. We will walk you through each step you need to take to fix your TV’s audio and visuals.

Why Your Insignia Smart TV Lip Sync Stopped Working

Your Insignia smart TV lip sync can stop working for several reasons.

The following are examples of situations where your audio and visual might go out of sync:

  • The cords that connect your audio device to your smart TV are loose
  • You’re using an outdated version of Insignia smart TV
  • The app you watch your shows on is experiencing updates or network issues
  • Your Wi-Fi is running slower than usual
  • You have too much cache data in your smart TV
  • Your smart TV has been on for too long

When you use your smart TV to watch your programs, you could encounter network problems or app issues that can cause your audio and visuals to go out of sync.

Depending on your problem, there are several methods you can use to resolve your syncing issues.

How to Re-Sync Your Audio and Picture on Insignia Smart TV

The first thing you need to do to troubleshoot your audio and picture on Insignia smart TV is to determine the problem.

Follow these steps to determine which troubleshooting method will work for your situation.

  1. Check your Wi-Fi speed on a computer, so you know if your Wi-Fi is out or faltering.
  2. Turn your TV off and back on to see if that resolves the problem.
  3. Try watching shows in another app to know if the app you’re using is the issue.

After you have ruled these options out, you can proceed with troubleshooting methods to fix your syncing problem.

Neglecting to try these things first could waste much time because many of these scenarios are out of your control.

For example, if the app you want to use is having connection problems or going through software updates, there’s nothing you can do about that aside from waiting it out.

Disconnect and Reconnect Cords

Disconnecting and reconnecting the chords attached to your Insignia smart TV and your audio device would be best.

This is the quickest way to resolve your syncing problems if your cords aren’t connected to your device properly.
