Why do I have a sound delay on TV?

It is possible for audio and video to be out of sync in several situations:

  1. When a video disc or Blu-ray player is attached, the issue can be triggered by a weak signal or the disc itself.
  2. If a home entertainment system has a digital optical cable, there may be a sound delay on the TV that has to be manually adjusted. There could even be a configuration on the TV itself that is the root of the problem.
  3. The audio may be slowed if the TV is attached to a speaker unit or a game system (through an HDMI connection or optical cord) because of time lag in the soundbar or game system platform's acoustics.

1. Directly connect the soundbar to the head device and turn off HDMI ARC output

When you have HDMI ARC or optical fiber connector on your music center, player, or speaker unit, sound delays on TV frequently occur.

The audio signal must travel further than the visual signal, which causes the lag. Although the video signal goes from the sender to the TV, the sound travels from the sender to the TV and then to the loudspeaker or home system.

You might have viewed the video before the speaker unpacks the audio stream. The music will follow the visual by a few nanoseconds. To fix it, follow these steps:

  1. On your controller, select the MENU/HOME icon.
  2. Access settings.
  3. Choose sound options.
  4. Select Sound/audio from the menu.
  5. Deactivate HDMI ARC/CEC.
  6. Directly link your source device to your speaker.

Setting the audio parameters on your TV is one of the most straightforward solutions for audio problems. Numerous problems, including sound delays on TV, echo, and lack of audio, will be resolved with this hack:

Setting new sound settings
  1. On your controller, hold the MENU/HOME option.
  2. Access system settings.
  3. Access the advanced system options page.
  4. Access the sound settings.
  5. Choose the Reset TV audio/picture settings option.

3. Reattach the TV to the source device

You may have sound delays on TV for various reasons, but one of the most frequently disregarded is a faulty connection.

Verify that the wires accompanying these gadgets are put in appropriately and safely. Remove every wire from your TV and source gadget, then reconnect each one at a time.

Your cables may be defective if the problem is still not fixed. Consider changing them out for fresh ones.

4. Turn the game mode on and off

The majority of TVs provide a Game Mode option that allows the TV to be set up to skip many control units, decreasing the period of time necessary for the TV to manage visual data while playing games.

Turn the game mode on and off

Activating Game Mode while playing video games can help reduce sound latency. When watching TV or playing a Blu-ray drive, deactivate Game Mode to avoid synchronization issues:

  1. Switch on the TV.
  2. Find the HOME switch on the remote control.
  3. Move into the settings.
  4. Decide on a photo or image modification.
  5. Select an alternative viewing mode, such as picture mode.
  6. Deactivate the Game Mode as required.

5. Erase cache

Think about erasing the cache if a specific program is causing sound lags on your TV.

Your TV's cache is a data storage area that gathers temporary data to speed up program loading.

Your TV's capacity can get overloaded with cached data over time, which might cause it to freeze and cause other problems like sound delays.

Your TV's functionality may be restored, and sound delay on TV may be avoided by clearing the cache:

  • Start your TV.
  • Find the HOME option.
  • Access settings.
  • Choose Your Applications.
  • Access the Manage Installed Applications section.
Erase cache
  • After choosing each program individually, click Clear cache.

6. Shut off background apps

A large amount of pre-installed apps are included with smart TVs. Although some of these applications are helpful, others take up space.

Certain apps will install naturally and operate in the quiet when your TV first turns on.

If several background apps are active, your TV may freeze or experience sound delays. Closing programs you are not currently using is the quickest fix for this issue:

  1. Find the HOME icon.
  2. Access settings.
  3. Choose Your Applications.
  4. Access the Manage Installed Applications section.
  5. Select Force Stop next to the app you wish to terminate.
Shut off background apps

Additionally, you want to think about removing all unused programs.

7. Find an alternate streaming app

For some reason, an app you are using may be to blame for a need to fix a sound delay on TV. You can hear sound delays on TV while streaming data from an internet source due to problems with the particular app.

Try choosing and installing a different streaming app after you've established that the app is the cause of your audio issues.

8. Factory reset your TV

  • Find Storage and Reset.
  • Go for Factory Data Reset.
