If facing “my MP4 has no sound” issue, there are a few workarounds that can effectively resolve the error. Follow stepwise guidance given below:

Method 1. Install the correct codecs

Audio codecs are software programs that encode and decode audio data in video files. When a codec is faulty or missing, the video plays with no sound at all. It happens when the media player is unable to decode the audio codec. To play video file with uninterrupted audio, users need to install the right codecs required for your media player.

• Choose About Windows Media Player from the list to open a new dialogue box.

• Click on the Technical Support Information option.

• In the pop up that appears, click on ‘Select your web browser’.
• A new tab will open on your browser displaying all the technical information about Windows Media Player including Audio codecs and Video codecs.

Method 2. Convert MP4 into another format

Maybe MP4 files aren’t compatible with your media player, which is why there’s problem with audio playing. There are two ways to convert your MP4 files to another format that’s compatible with your media player. Either you can use an online MP4 converter or use VLC media player.
