Sound delay issues are not uncommon on modern TVs. They happen even to the best TVs on the market. If this happens to you, don’t panic! Several circumstances can lead your audio and video to be out of sync. In most circumstances, the audio format you are watching might have issues. If you have connected your TV with an external audio source like a soundbar or Home theatre and you are experiencing sound delays, it is probably not in sync with the TV.

KEY TAKEAWAYS:

  • Several circumstances can lead your audio and video to be out of sync. In most circumstances, the audio format you are watching might have issues.
  • Anything projected from your TV will have two parts; picture and sound. To experience perfect sync, both audio and sound need to get to the outputs simultaneously.
  • If you own a Smart TV, make sure that it has the latest software updates/firmware installed. Outdated software often leads to glitches that can affect the sound.

There’s also the possibility that your external audio settings have not been appropriately configured, leading to a sound delay. Regardless of the issue, in this post, we will outline how to fix sound delay on a TV.

What causes the Audio Delay?

Before we get to the troubleshooting options, it’s worth understanding the issues behind sound delay on a TV. Fortunately, these issues are nothing complicated and typically come from a very simple place—TV and sound system connections.

The audio and video projected from your TV are produced by a source such as a video game console, Blu-ray player, Cable TV box, or even the TV itself. Anything projected will have two parts; picture and sound. To experience perfect sync, both audio and sound need to get to the outputs simultaneously.

Here’s where the problem comes in, picture and audio travel through different paths. For example, if you have a soundbar, the sound travels from the source to the TV to the soundbar, taking a relatively longer time than the picture, which travels a shorter distance from the source to the TV. Altering or fixing the screen resolution on tv may be one of the reasons for this problem. Properly setting up a soundbar can also decrease the likelihood of this happening.

If you are experiencing this problem, we have a fix.

Fixing Sound Delay on a TV

There are several reasons why your TV is experiencing sound delays, including the following:

  • If you are using a Cable TV box, the broadcaster could have a bad connection or is experiencing technical issues.
  • You could also have a poor connection with sources like Blu-ray players, gaming consoles, or a Cable TV box. A poor connection can cause many problems with your TV. Something as simple as a loose HDMI cable can cause a blue screen on your TV. If the HDMI port is faulty it can cause a high-pitch noise to come from your TV. It is important if you have experienced either of those to read the guides we have.
  • If your home theater is not connected to your TV with an optical cable, there may be an audio delay caused by processing delays in your audio system. This is not a problem caused by your TV speakers.
