These files often contain both video and audio streams, making them a convenient format for multimedia playback.

VOB (Video Object) files are typically used for storing DVD video and audio. If you're encountering an issue where the VOB file has no audio, there could be several reasons for this:

  • Missing or Corrupt Audio Stream: The audio stream within the VOB file may be missing or corrupt. This could have happened during the ripping process or due to some error in the creation of the DVD.
  • Codec Issue: The audio codec used in the VOB file may not be supported by your media player or system. In such cases, you might need to install additional codecs or use a different media player.
  • Playback Device Compatibility: Some devices may have trouble playing certain audio codecs or formats. Make sure the device you're using supports the audio codec used in the VOB file.
  • Volume Muted or Low: It may seem obvious, but sometimes the audio is simply muted or the volume is set too low. Check your media player settings to ensure the audio is not muted and the volume is turned up.
  • Damaged File: The VOB file itself may be damaged or incomplete, resulting in the absence of audio. Try playing the file on a different device or using a different media player to see if the issue persists.

5. Convert the VOB File

If you're unable to play the VOB file with audio, try converting it to a different format using video conversion software like HandBrake or Format Factory. Choose a common audio format like MP3 or AAC for the output file, as these formats are widely supported by most media players and devices.

If you're trying to play the VOB file on a specific device (e.g., a smart TV, gaming console, or mobile device), make sure that the device supports the audio codec used in the file. Check the device's user manual or specifications online to verify its audio codec compatibility.
