Solution: VLC Player Doesn't Have Sound

VLC Player is a widely used player and encoder that supports many video and audio formats. Like other software, VLC users may experience various technical problems. Even though it has been installed on your computer for a long period of time and you have already used it many times, it may fail to function properly. One of the common technical problems you might often experience is VLC no sound. Here are some ways to help you solve VLC no sound problem.

• Solution 1: Unmute Your VLC Player
• Solution 2: Adjust Audio Settings
• Solution 3: Convert Video Format

Solution 1: Unmute Your VLC Player

If VLC media player is playing video but no sound playing, the probable cause is that you may have set it to mute at some point, and forgotten all about it. Your computer’s operating system may remember this setting and mute VCL the next time. To unmute your VLC, just follow the steps below:

1 Click the speaker icon (it's at the bottom of your task bar near your clock);

2 Click the “mixer” and if your VCL Player is running, it will show up in the mixer like below;

3 Then unmute VLC and your sound works again

Solution 2: Adjust Audio Settings

If it doesn’t work after you unmute VLC, try adjusting audio settings of this player. Here is how: go to Tools > Preferences > Audio and make sure Enable audio is ticked. Then go to Output and try a different default.

Solution 3: Convert Video Format

If it still doesn’t work after trying the solutions above, you may convert the original video to another format, because VLC may have troubles playing some MKV or MP4 media file. Here I introduce a powerful Video Converter to help you convert your media file.
