This can disrupt the media experience, rendering users unable to enjoy sound even though video playback may be functioning correctly.

Understanding the Issue

The "Channels: Unknown-chan-mask" error typically arises due to an unsupported audio format or codec issue. Various factors can contribute to this, including outdated VLC versions, incompatible audio drivers, or specific audio settings within VLC itself.

  2. Audio Drivers: Outdated or corrupt audio drivers can prevent VLC from playing sound correctly.
  3. Audio Output Settings: Incorrect audio settings in VLC can lead to audio playback problems.
