How to troubleshoot an audio delay

Last Update date : Mar 09. 2022

Have you ever sat down to watch a movie or play a game and notice that the sound is out of sync with what you’re watching? If you have connected your TV to a soundbar or other external device, this is a common issue. Follow the troubleshooting guide below to fix the audio delay issue you are experiencing.

Why does an audio delay occur?

Depending on the broadcasting signal transmitted by the broadcasting station, an audio delay may occur in some or all of the TV programs they are broadcasting. There is a slight difference in processing speed between video and audio signals. Usually the difference is not notable, however sometimes it is.

If it’s not due to the broadcaster, another reason an audio delay often occurs is a bad connection to an external device you’ve connected to the TV. Sometimes, an external device such as a set-top box will produce a slight difference because of the transmission speed of the video/audio signal from the set-top box to the TV. Follow the troubleshooting guide below to fix your audio delay issues.

Step 4. Increase or decrease the digital audio output using the slider.
