Prerequisites & Requirements

Before attempting to fix lip sync issues, ensure you have the following:
  • •A TV with adjustable audio settings or a compatible external audio device.
  • •Access to the TV remote control or the TV's physical buttons.
  • •An updated firmware version for your TV or audio device.
  • •A stable internet connection if streaming content.

Method 1: Adjusting Audio Delay Settings

This method is useful when your TV has built-in audio delay settings that can be adjusted to sync audio and video.
  • •Step 1: Press the 'Menu' button on your remote control to access the TV's settings.
  • •Step 2: Navigate to 'Audio' or 'Sound Settings' using the arrow keys and select it.
  • •Step 3: Look for 'Audio Delay' or 'Lip Sync' options. Adjust the delay settings (usually in milliseconds) until the audio matches the video.
  • •Step 4: Test the adjustment by watching a scene with clear dialogue to verify the sync. If it doesn't work, repeat the steps and adjust further.

For Windows 11

If using a Windows 11 PC connected to the TV, follow these steps:
  • •Right-click the speaker icon in the taskbar and select 'Sound settings'.
  • •Under 'Output', select your TV and click on 'Device properties'.
  • •Scroll down to 'Advanced' and adjust the 'Audio enhancements' or 'Audio delay' settings.

For Windows 10

For Windows 10 users, the steps are slightly different:
  • •Right-click the speaker icon in the taskbar and choose 'Playback devices'.
  • •Select your TV from the list and click 'Properties'.
  • •Go to the 'Enhancements' tab and look for 'Audio Delay' settings to adjust.

Method 2: Checking Connections

If adjusting audio settings does not resolve the issue, checking physical connections may help.
  • •Step 1: Ensure all cables (HDMI, optical, etc.) are securely connected to both the TV and the audio source.
  • •Step 2: If using an external sound system, check that the audio output settings on the TV match the input settings on the sound system.
  • •Step 3: Test different HDMI ports on the TV, as some ports may have different processing speeds.
  • •Step 4: If using a streaming device, restart it and check for any firmware updates.

Troubleshooting Common Issues

If you encounter problems while trying to fix lip sync issues, consider the following solutions:
  • •Error: 'No audio output' - Solution: Check if the correct audio output device is selected in settings.
  • •Issue: 'Audio still out of sync' - Fix: Restart the TV and the audio source, then recheck the audio delay settings.
  • •Problem: 'Lip sync issues only with certain apps' - Workaround: Check for app-specific audio settings or updates.

For power users, here are some advanced tips and shortcuts:
  • •Keyboard shortcut: 'Windows + I' - Opens Settings quickly for adjusting audio settings.
