Enable AV Sync Adjustment

You should check the Audio-toVideo Synchronization settings if your TV’s video and audio are not in sync or the sound is too slow.

The AV Sync adjustment setting can be used to reduce the lag between audio output and visual. This will help you fix annoying and frustrating sound delays.

Connect the source device directly to external speakers

Audio delays can often occur when your TV is connected directly to your soundbar, home theatre, or external speakers using HDMIARC or optical out.

The delay is caused by the audio signal traveling longer than the video signal. The video signal travels only from the source device and the TV.

You would have seen the video by the time that the soundbar has unpacked the audio signal. The sound will arrive in a few seconds after the visual display.

This can be prevented by connecting your soundbar to the source device directly and disabling HDMIARC audio output.

These are the steps:

  1. Use your remote to press the MENU/HOME key
  2. Go to Settings
  3. Choose sound settings
  4. Navigate to the “sound/audio Out” section.
  5. Turn HDMI ARC/CEC Off
  6. Connect your source device to your soundbar directly

Reset Sound Settings

Resetting the TV’s sound settings is one of the fastest ways to fix audio lags. This hack can fix many issues such as audio delays, echoing and no audio.

Method 3 – Power Reset Using Remote Control

Reconnect your TV to the Source Device.

A number of issues can cause your TV to sound sluggish. One of them is a poor connection.

An out-of-sync sound can result from a poor connection between your TV’s source device and the source device (e.g. a cable box or Blu-ray Disc player)

Verify that the cables are properly and securely connected to these devices. Unplug all cables from your TV or source device, and reconnect them one at a time.

Your cables may be defective if the problem persists. You can replace them with newer ones.

You can enable or disable the game mode according to your preference

Many TVs have a Game Mode feature. This allows the TV to bypass multiple video processors and reduces the amount of time it takes to process video signals.

Game Mode can be enabled during gameplay to reduce sound delays while playing video games. To avoid audio problems, disable Game Mode while watching TV or using Blu-Ray discs.

These are the steps:

  1. Turn on your TV
  2. Go to Settings
  3. Navigate to the picture or make adjustments

Clearing the cache may be an option if you experience sound delays on your TV due to a specific app like Netflix or YouTube.

A cache is a location on your TV’s memory that stores temporary data, allowing apps to load quicker.

Over time, cached data can build up and fill up your TV’s memory. This can cause it to freeze, which could lead to other problems, such as sound delays.

Clearing your cache can restore functionality and prevent audio lags.

These are the steps:

  1. Turn on your TV
  2. Navigate to Settings
  3. Choose Applications
  4. Navigate to Manage Installed Applications
  5. Click on each app individually and then click “clear cache.”

  1. The HOME button can be pressed on the remote control.
  2. Navigate to Settings
  3. Choose Applications
  4. Navigate to Manage Installed Applications
  5. Click “Force Stop” on the app that you wish to close.

It is also a good idea to delete any apps you don’t use or plan on using. These apps can always be added back later.

Manufacturers frequently release updates to fix bugs or issues that may affect their products. Updates to your TV’s software can help solve sound delays.

These are the steps:

  1. Connect your TV and the internet
  2. Use the remote control to press the HOME/MENU button
