First test another channel.

If only one channel has no sound, send support the exact channel name.

You can also:

  1. Open the audio-track menu in your player.
  2. Select another available audio track.
  3. Restart the player.
  4. Try another compatible player.

If all channels have no audio, check the device's audio output settings.

Why is the audio in the wrong language?

Some streams include multiple audio tracks.

Open the player controls and look for:

Audio Audio Track Language

Then choose the language you prefer if it is available.

If the correct language is unavailable on a specific channel, send support the channel name.

Also check mute and volume on the player, device and TV. For HDMI audio problems, check the TV output format; PCM can be tested if available.
