How to Resolve Video No Audio Problems: Quick Fixes

Due to their visual value, videos always stand out as a powerful medium for communication, education, and entertainment. However, common issues, such as video no audio, can disrupt the viewing experience. Whether due to glitches or compatibility issues, silent videos can leave viewers disengaged. As we know, audio plays a crucial role in delivering context, so its absence places a significant barrier to communication.

Resolving the “no sound on video” issue is essential to ensuring that content creators can engage their audience. Throughout this article, we will try to familiarize you with several solutions available to get rid of this problem. Thus, follow along if you want to enhance the viewing experience when faced with videos that lack sound.

Part 1. Most Common Potential Reasons for Video No Audio

Understanding why the “video no sound” issue happens is the first step to finding effective solutions. Thus, here are some common reasons your visual content might lack sound:

1. Compatibility Issues: The audio formats used in your video may not be supported across all devices and platforms. When your file uses an unsupported format, the sound may fail to play despite the visuals working fine.
2. Missing Codecs: Generally, audio tracks require specific codecs to decode and play. If these codecs aren’t installed on your player, the audio remains silent.
3. System Settings: Sometimes, misconfigured audio settings, such as muted sound output, can block audio. Even small tweaks in your settings may unintentionally silence the video.
4. Corrupted Video Files: You can also face the “no sound on video” problem when your file loses its audio track due to corruption. This issue usually occurs during file transfers, downloads, or improper saving processes.
5. Outdated Drivers: Most of the time, older media players or sound drivers may not support newer video and audio formats. Without updates, these tools struggle to process your video files.

Part 2. Some Quick and Effective Fixes To Video No Audio Issue

Despite the common belief, dealing with videos that lack sound doesn’t have to be a headache. Upon increasing the MP4 volume online or applying the right fixes, you can get the job done. The following fixes will ensure your videos deliver a seamless audio-visual experience:

Solution 1. Check System Sound Settings

Sometimes, the simplest “video no audio” problem arises from overlooked system settings. When your video has no audio, start by ensuring that your device’s sound isn’t muted. Go through the steps given below to optimize your system settings to fix this error:

1. Initiate this task by launching the “Settings” application on your device and entering the “System” settings. Once you access all options, tap on the “Sound” settings to proceed.



2. You need to pick the desired speaker through which you want to play the sound. Within the “Volume” section, drag the slider if the volume levels are too low.

Solution 2. Change Media Player For Video

Not all media players are equal, and sometimes, the one you're using might not support the audio format of your video. Such a basic media player can result in the “no sound on video” issue during playback. So, we recommend you switch to a more versatile media player, like VLC Media Player. With support for a wide range of audio and video codecs, this media player appears as a reliable option for playing almost any file format.

Once installed, open the problematic video in the new player to check if the sound works. Additionally, these advanced media players allow you to troubleshoot the issue by identifying missing codecs and suggesting fixes.

Solution 3. Use Video Volume Booster Online

Sometimes, the issue isn’t a complete lack of sound but simply a low volume that’s hard to detect. Several online tools allow you to boost the volume without needing to download additional software. Take guidance from the steps below to learn how to increase MP4 volume online with tools like Video2Edit.

Solution 4. Download Appropriate Video/Audio Codecs

If you are still facing the “video no audio” issue, the problem might be due to missing codecs. Such codecs are essential for decoding and playing audio and video files. One of the best ways to fix this issue is by downloading a codec pack, such as the K-Lite Codec Pack. Go through these steps to fix the issue with this simple solution:

1. Start by reaching the official K-Lite Codec Pack download page to kickstart this task. Upon choosing your desired codec pack, tap on the "Download" button to proceed.

Solution 5. Fix Corrupted Video No Audio With VLC

Usually, corruption in video files can cause the audio to malfunction, even if the video itself appears fine. Fortunately, VLC Media Player offers a feature to repair damaged or corrupted video files. However, users need to convert formats like MP4 to AVI before fixing the issue. Follow the steps below to resolve the “no sound on video” issue with ease:

1. After changing the file extension of your video to .AVI, open this media player on your device. Moving forward, simply hit the “Tools” menu and select “Preferences” from the dropdown options that appear.
