There could be several reasons why you can’t hear any sound when you play a video. Here are some common causes and solutions:
Corrupt video: If you have downloaded a corrupt video, it may not have sound. Download the correct file and try playing it again.
Missing codecs: If you are missing codecs, the video may not play sound. Codecs are software components that encode and decode digital media formats. Install the required codecs to fix the issue.
Third-party video players: If the default video player is not working well with unusual video types, use a third-party player that supports all formats. There are many free and reliable video players available online.
