When you play any video file, be it MP4 or MOV, audio and video components are usually essential for the video to play. However, sometimes you may encounter an MP4 file with no sound, which can be frustrating and confusing. Do not worry. This article helps you learn everything you need to know about MP4 issues and how to fix it quickly.
No sound in MP4 refers to the absence of audio in an MP4 multimedia file format. MP4 files are designed to store audio and video data, but when there is no sound in an MP4 file, it means that the audio component of the file is missing or corrupted.
Why is My MP4 Video File Playing with no Sound?
When your MP4 has no sound, it means that the audio component of the MP4 file is not playing or is missing entirely. This issue can occur due to various reasons, such as:
- Missing or damaged audio codec: The audio codec used to encode the audio component of the MP4 file might be missing or damaged, preventing it from playing.
- Misconfigured media player: The media player you have selected to play the MP4 file may be misconfigured or not set up to play audio.
- Mute or low volume: The audio may be muted or set to a low volume in the media player or the system's sound settings.
- Incorrect audio settings: The audio settings of the media player or the system may need to be corrected or set up correctly.
- Hardware issues: Issues with the hardware, such as faulty speakers or headphones, may cause the audio component of the MP4 file not to play.
- MP4 file does not have sound by itself: If the MP4 video you are trying to play does not have audio, then it won’t play sound.
- MP4 file corruption: When an MP4 file becomes corrupted or broken, it can result in audio playback issues or MP4 video itself not showing problems.
