Why Does My Video Play With No Sound?

If a video plays but there is no sound, the video stream may be supported while the audio codec is missing.

Quick answer

If a video plays but there is no sound, the video stream may be supported while the audio codec is missing.

Common causes

  • The file uses DTS, AC3, AAC, or another audio codec your player cannot decode.
  • The player may be using the wrong audio output or decoder.
  • The media file could be muted, damaged, or partially downloaded.

What to try

  • Test the file in another player to see if audio is present there.
  • Install Media Player Codec Pack so Windows and compatible players gain broader audio support.
  • Check speaker, output, and mute settings if every file is silent.

All editions of Media Player Codec Pack are free to download.
