Here’s why desynchronization appears between the Samsung soundbar and TV:

  • The TV’s equalizer preset is causing desynchronization.
  • A fault with the soundbar’s wireless or wired connection.
  • Media with complicated or incompatible encoding format.
  • Improperly adjusted “Sound Delay” options from your TV.
  • A hardware issue with the soundbar or the connected TV.

Well, those are the possible causes for the Samsung soundbar’s delay in audio or video, which is often referred to as “lip sync”.

So, keep reading to reveal the top-working steps and methods. 

Samsung TV and Soundbar Out of Sync – Here’s the Fix!

Tip: Follow the guide chronologically!

1. Use the Soundbar’s “Audio Sync”

All Samsung soundbars have an “Audio Sync” function that synchronizes the time and quality of the audio playback.

So, if your Samsung soundbar’s remote does not have a separate “Audio Sync” button, you must use the “Audio Settings” controller to choose from “TREBLE,” “BASS” and “AUDIO SYNC.”

Here’s how to adjust the Samsung soundbar’s “Audio Sync” function:

  1. First, play any audio or media on the Samsung TV.
  2. Press “Sound Control” on your soundbar’s remote.
  3. Next, use the Left/Right buttons to adjust the delay.
Note: The level of synchronization will be displayed on the Samsung soundbar’s screen while the feature is being adjusted.

2. Play Media with Different Encoding

play media with different encoding

In many cases, the audio or video of a particular TV show or movie is falling behind because of a specific encoding format.

So, it takes a moment for a Samsung soundbar to receive the audio packets from the TV, unpack the signal, and send it out with the corrected audio and video sync.

So, formats using higher audio quality and containing more data such as Dolby Digital, Dolby Atmos, and even DTS can cause the sound or video to fall behind.

Well, you can test the TV’s encoding capabilities and sync by playing a video or broadcast with a standard audio format.

Important: Connect the Source Directly!

If you’re using a separate source device, such as Roku, Firestick, or a cable TV box, you should connect it directly to the soundbar.

This way you can bypass any audio delay caused by the TV because the source device will be passing the video signal through the Samsung soundbar first.

Note: The issue most often occurs on Optical out or HDMI ARC connection!

3. Adjust the TV’s “Audio Delay” Options

All Samsung TVs allow to manually regulate the delay between the output audio or video.

You can either increase or decrease the audio delay, based on whether the soundbar’s playback is behind or forward of the TV’s video.

Here’s how to adjust the audio delay feature on your Samsung TV:

  1. First, press the “Home” button on the remote control.
  2. Go to “All Settings” → “Sound” → “Expert Settings.”
  3. Scroll down and press “Digital Output Audio Delay.”
  4. Next, increase or decrease the delay using the slider.
  5. Exit the menu and test your Samsung soundbar sync.
  • Well, by moving the slider toward the left will decrease the delay, and moving it toward the right increases it.

Calculate by how much is the audio or video falling behind and adjust the Samsung soundbar’s delay accordingly.

4. Reconnect Your Samsung Soundbar
