If you are wondering why a problem, such as audio being out of sync with the video, occurs, there are many possibilities. In this part of the article, you are about to learn the common causes of audio delay and how to quickly run a diagnosis of the video and your device.

1. Common Causes

One of the most common causes of audio delay in a video is high video resolution or the use of special effects. If your device can barely support high definition, the audio will definitely play first. Additionally, if you are using an external device such as a soundbar, there is a high likelihood of audio lag in the video. Other than that, here are more causes of audio delay to consider:

• Streaming videos online with a slow internet connection.
• Bugs in media players are causing desynchronization.
• Loose HDMI cable or other faulty connections.
• Video variable frame rate that is not supported by the device.

2. Quick Diagnosis Tips

The easiest way to check whether audio and video are out of sync is to switch or close the media player you are using. Try playing the video on another device to see if the problem is in the media file or the device itself. If these simple tips do not solve the problem, check the next part for more advanced solutions.

To synchronize the audio in the video, you can use the following methods. This section outlines general solutions you can try to address the audio delay.

1. Restart Everything

Start by force-closing the media player application. If you are streaming online, close the website, including any open tabs. Then, restart the device and try playing the video again.

2. Check and Update Everything

The operating system of your computer or phone plays a pivotal role when there is an audio delay. Make sure your device is up to date to remove any unseen bugs that could be causing the video issue.

3. Check Your Internet Connection

A slow internet connection can be the very reason for the audio delay in the video. Consider unplugging and restarting the internet router. Connect to another internet network if necessary.

4. Disable Audio Processing

Audio enhancements are activated on modern devices by default. To turn it off, go to the settings and search for "AI" or "Audio enhancements." While this feature helps with clear audio recording, it can hinder video playback.

Toggle off the Turn on fast startup (recommended) option and save the changes.
