Part 1. Major Causes of Audio Problems on Video Files

Combined with actual testing and feedback from numerous users experiencing the same problem, we've summarized a few possible triggers. Check your files and playback devices against them first to see which one you fit.

• Media Player Does Not Support Audio Formats

To watch a video with sound on a media player, you have to make sure that the platform supports both the video and audio codecs for that file. If the player you're currently using lacks a codec that can read audio, then you'll experience audio lag or even complete failure to play.

• The File Is Corrupted

If your recording software or equipment malfunctions, or if your device suddenly shuts down while you're recording an audio video, your saved file has likely been corrupted. Improper saving and malfunctioning storage devices may also induce problems such as audio loss and video not playing correctly.

• Wrong Audio Settings

Another possibility is that the audio settings in the playback software or device have not been adjusted properly, such as the audio channel configuration or sample rate mismatch. This kind of problem can cause the player to fail to read and play smooth and complete audio.

You also should check that the media volume has not been adjusted to mute.
