When the TV takes time to process the image and audio, which passes through several circuits before being displayed on the screen or coming out of the speakers, you have latency. This can cause a delay between what is shown and what is heard on your television.

Because of the low latency, the hardware capabilities are adjusted in such a way that the picture becomes smooth and does not use the highest acceleration, leaving room for the sound to be appropriately adjusted. Turning off low latency is your best bet.

Disable video and audio processing​

You may need to go to the sound bar menu and adjust the equalizer settings for this.
