“How to fix audio video sync permanently? I have found that the audio is not in sync with video, and I do not know how to make it function properly. What is the best way to resolve the audio out-of-sync issue?
What’s worse than watching a video that isn’t in sync? The perfect storm of frustration and discomfort when you can’t enjoy your content as it should be seen. Luckily, we’re here to help with our complete article that will share multiple ways to fix audio video sync permanently across different platforms, including macOS, Windows, Android, and iOS.
There are two types of issues that users usually face when watching a clip. One is that the audio is ahead of the video, which means the audio plays before seeing any content on the screen. The other scenario is when there is an audio delay. It occurs when you can see the video’s content first without sound.
Such situations usually occur when you play a video from an old DVD, have downloaded the clip from an unreliable site, or play the file on an error-prone media player. Other reasons are as follows:
- Playing the video on a media player that doesn’t support its file format
- Corruption due to malware attacks--either self-inflicted through poor practices such as download clicking onto contaminated websites
- Incorrect settings on your device
- An outdated media player
- The video was not downloaded properly
