  1. Audio and video out of sync on TV

Suppose you watch a movie or any video on TV and notice that the audio is out of sync with the video. In that case, we recommend checking the TV settings. It will help if you start by disabling the device’s video-processing settings, like motion enhancement and similar picture-related options. Also, check the external sources, such as HDMI cable, if you have connected your computer with the TV.

  1. Audio and video out of sync on Windows 10

If the synchronization error occurs on your Windows 10 desktop, then we suggest checking if the graphics and sound drivers are updated to their latest versions or not. For that, go to Settings, and access the Device Manager utility. Select the driver, and update it accordingly.

  1. Audio delay on youtube or other social media channels

Audio delays on online streaming sites, such as Netflix or Youtube, are usually caused by a poor network connection. Check to see if the WiFi is working properly or not.

  1. Audio lagging behind the video in local video or DVD

Whenever you access a local video or DVD with an audio lagging problem, the typical reason behind it is either a corrupt file or a broken disc. In that case, either download the video from a trusted source or burn the video on a separate disc.
