Part 1: Why Is MP4 Video No Sound?

Before we proceed to the solutions, let us first understand the common causes of MP4 video having no sound. MP4 is a popular video format that can store both video and audio data in a single file. However, sometimes the audio data may be missing, corrupted, or incompatible with the media player or device that you are using. Here are some of the possible reasons why no sound mp4:

Reason 1: Codec Error

A codec is a software or hardware component that encodes and decodes the audio and video data in a media file. Different MP4 files may use different audio codecs, such as AAC, MP3, AC-3, or Opus. If your media player or device does not support the audio codec that your MP4 file uses, it may not be able to decode the audio stream and play the sound. This is one of the most common reasons why MP4 has no sound.

Reason 2: Corrupted File

Another reason why MP4 video has no sound is that the file itself is corrupted or damaged. This can happen due to various factors, such as incomplete downloading, virus infection, software malfunction, or unexpected system shutdown. When the file is corrupted, it may lose or misalign some of the audio data, resulting in no sound during playback. This can also affect the video quality and cause other issues, such as freezing, stuttering, or pixelation.

Reason 3: Player Glitch

A third reason why MP4 has no sound is that the media player that you are using is glitchy or malfunctioning. Sometimes, the media player may have some bugs, errors, or outdated components that prevent it from playing the sound properly. This can also be affected by the audio settings, volume level, or output device that you have configured on your media player or device. In this case, the problem is not with the file, but with the player.

Now that we know the possible causes of MP4 video having no sound, let us see how to fix mp4 with no sound with 5 simple solutions. You can try these methods one by one until you find the one that works for you.

Solution 1: Check the Audio Settings on Your Device

The first solution that you can try is to check the audio settings on your device and make sure that they are not muted or too low. Sometimes, the problem may be as simple as adjusting the volume level or selecting the right output device.

To do this, you can follow these steps:

• On Windows, right-click on the speaker icon on the taskbar and select Open Sound settings. Then, check the output device and the volume level under Master volume. You can also click on Troubleshoot to run the audio troubleshooter and fix any issues.

Solution 2: Try Another Media Player

The second solution that you can try is to use another media player to play your MP4 video and see if it has sound. Sometimes, the media player that you are using may not support the audio codec that your MP4 file uses, or it may have some glitches that prevent it from playing the sound. In this case, you can try a different media player that supports more audio codecs and has fewer bugs.
