What Is Audio Delay on TV?

Audio delay, also known as audio latency, is a common issue when the sound output on your TV is out of sync with the video on the screen. This means there is a noticeable delay between the audio and video, making it appear that the audio is lagging behind the video.

Audio delay can be frustrating when watching movies, TV shows, or playing video games, as it can ruin the viewing or gaming experience.

What Causes the Audio and Video Out of Sync on TV?

If you notice the audio and video out of sync on TV, it could be due to several reasons. Some of the most common causes include:

  • Incorrect TV settings
  • Processing delays
  • Issues with the cable or satellite box
  • Using external speakers with a delay
  • Outdated TVs that struggle with modern video processing technologies

Additionally, factors like signal transmission speed, video quality, and playback speed can cause audio-video sync issues on a TV.

How to Fix Sound Delay on TV

If you notice your TV audio out of sync, here’s a list of fixes you should try to resolve the audio sync issue in no time.

Note: Below, we’ve listed general steps for each fix. You should check the user manual for specific TV models and brand steps. Or, even better, check YouTube!

1. Perform a Soft Reset on Your TV

Soft resetting your TV is crucial in resolving any issues you may encounter while using it. This straightforward process can help fix problems like buffering or slow apps, unresponsive remote controls, black screens, frozen displays, and sound delays.

To perform a soft reset on your TV, switch it on and disconnect all external devices beforehand. There are three methods you can use to soft reset your TV:

Via Power Cable

Unplug Your Tv
  • First, disconnect your TV from its power source.
  • Wait for a minute before plugging it back in.
  • Once the time is up, plug your TV back in (don’t use a power strip or extension for now).
  • Turn the TV back on and see if that resolves the sound delay on your device.

Via TV Menu

  • First, click on the Home button on your TV remote.
  • Navigate to Settings > About > Restart.
  • Click on “Confirm”.

Via Remote Control

Soft Reset Via Remote Control
  • Power on your TV and direct the remote towards it.
  • Hold down the power button for around 10 seconds.
  • Once you do that, your TV will turn off and restart automatically.

Now, check if that resolves the TV audio out of sync issue. If you’re still experiencing the same trouble, move on to the following method.

2. Reconnect Your TV to the Source Device

Are you experiencing sound delays on your TV? One of the most common culprits could be a poor connection between the source device (a DVD player, Blu-ray Disc player, or cable box) and your TV. This can occur when cables are not securely plugged in or faulty.

Check And Secure All Cable Connections

To troubleshoot, check that all cables are securely connected. You can even try disconnecting and reconnecting them one by one. If the issue persists, replace your cables with new ones.

3. Check Different Channels for Delay

To troubleshoot an audio and video sync issue on your TV, try switching the broadcast. This can help you determine whether the problem is with the source you were watching or your TV.

If your TV uses an antenna, browse the other channels to see if the issue is limited to just one channel. For cable TV users, test the sync on other channels to identify the problem.

If the out-of-sync problem is limited to a certain channel or a specific application, the issue may not be with your TV. However, if the issue persists across all media and channels you’re watching, the problem is likely more serious and requires further troubleshooting.

4. Update Your TV’s Firmware

If you’ve tested the previous fixes and the sound delay issue still persists, it may be time to update your TV’s firmware.

Companies often release software updates to improve their products’ performance and fix bugs. Updating your TV’s software could be the solution to your sound delay problem.

To update your TV’s firmware, follow these steps:

Update Smart Tv Firmware
  • Make sure your TV has access to the internet.
  • Click the Home/Menu button on your TV remote control.
  • Go to Settings > System Settings > Software Update (could also be Firmware Update).
  • If there are any new software versions available, select Update Now.

5. Reset Audio Settings

If updating the TV’s firmware didn’t work, resetting your TV’s audio settings is an effective method to address several problems like sound delays, echoing or no audio.

The process of resetting sound settings is straightforward and fast.

Follow these simple steps to do so:

Factory Reset Audio And Video Settings
  • Click the Home/Menu button on your TV remote.
  • Navigate to System Settings and open Advanced System Settings.
  • Now, select the sound settings.
  • Choose the option to reset TV audio/picture settings.

6. Adjust AV Sync Settings

Most modern TVs include an AV Sync Adjustment feature that can help you rectify audio and video out of sync on TV effortlessly.

Try toggling the AV Sync setting to reduce the lag between the visual display and the audio output, eliminating any frustrating delays.

To do this, follow these simple steps:

Toggle Av Sync Adjustment
  • Click the Home/Menu button on your TV remote.
  • Select the Settings option.
  • Navigate to Sound Settings and look for AV Sync Adjustment.
  • Turn on the AV Sync Adjustment feature.
  • Toggle the “Audio Out” slider left or right as needed to reduce sound delays.

7. Directly Connect the Source Device to External Speakers

Audio delays are common when using HDMI ARC or optical output to connect a TV directly to a home theater, soundbar, or external speakers.

This is because the audio output has to travel a greater distance than the video output. As a result, the sound may arrive a few microseconds after the video, creating an out-of-sync effect.

To address this issue, it’s recommended to disable HDMI ARC audio output and connect the soundbar directly to the source device.

Follow the steps below:

  • First, access the settings on your TV.
  • Navigating to the sound settings
  • Turn off the HDMI ARC/CEC option from the menu.
  • Once disabled, connect your soundbar directly to your source device for optimal audio and visual synchronization.

8. Enable or Disable Game Mode

Most modern TVs have a “Game Mode” feature that bypasses certain video processors, reducing the time required by your TV to process video signals while playing video games.

Activating this mode can reduce sound delays during your gameplay. However, it’s best to turn off Game Mode while playing a Blu-Ray disc or watching TV to avoid any audio issues.

To enable or disable Game Mode on your TV, follow these simple steps:

Enable Game Mode
  • Click the Home button on your TV remote control.
  • Navigate to Settings and open Picture or Picture Adjustments.
  • Choose the special viewing mode or picture mode option.
  • Turn Game Mode on and off accordingly.

9. Clear Cache

If you’ve noticed the TV audio out of sync while using apps such as YouTube or Netflix, removing the cache might help.

The cache file is a memory storage location inside your television that accumulates temporary data, which enable apps to load more quickly. However, over time, these cached files can fill up the TV’s memory, causing it to experience issues like sound delays, frozen screens, etc.

To prevent sound delays and other functionality issues from happening, follow these simple steps:

Clear App Cache
  • Click the Home/Menu button on your TV remote control.
  • Go to Settings.
  • Choose the Applications tab.
  • Go to Manage Installed Applications.
  • Choose each app individually and select “Clear cache“.

Clearing the cache can restore your TV’s functionality and prevent audio lags.

10. Close Background Apps

Smart TVs often come equipped with numerous pre-installed apps, some redundant or unnecessary.

When the TV is powered on, some of these apps may start running in the background, leading to performance issues such as freezing and sound delays.

To address this problem, it’s recommended to close any apps that aren’t currently in use.

Here’s how to fix sound delay on TV by closing the background apps:

  • Navigate to the Settings menu by pressing the Home button on your TV remote.
  • Select Applications then click on Manage Installed Applications.
  • From there, you can choose the app you wish to stop and tap on “Force Stop“.

If there are apps that you don’t use or don’t plan on using, it’s worth considering deleting them altogether. This can help free up space and improve overall performance. You can always reinstall apps at a later time if needed.

11. Use an Alternative Streaming App

If you’re experiencing sound delays while streaming content on your TV, it’s possible that this particular app is causing the issue.

Once you’ve confirmed that the app is the culprit, try installing another streaming app on your TV.

Depending on your TV brand or model, there are several app options available on platforms like the Google Play Store, SmartCast, and Apple App Store. These apps could potentially resolve the sound delay problem and enhance your streaming experience.

12. Perform a Factory Reset on Your TV

If using an alternative streaming app didn’t resolve the sound delay issue, it’s now time to reset your TV to its default settings.

To reset your TV to its original state and potentially resolve problems like sound delays, follow these simple steps using your TV’s original remote control:

  • Hit the Home button on your TV remote.
  • Choose “Settings” and then “Storage and Reset“.
  • Click on “Factory Data Reset“.
  • Reboot your TV.

It’s important to remember that factory resetting will delete all personal data and settings, except for pre-installed apps. Again, this process will return your TV to its original state as if you just bought it from the store.

If factory resetting your TV still didn’t resolve the audio delay issue, contact the support team of the TV brand for further assistance.
