Issue: No sound when playing a video from a digital media player connected through HDMI, such as an Apple TV or Roku.

Apple TV (depending on model/iOS):

  1. From the Apple TV home screen, select Settings.
  2. Select Audio & Video.
  3. Select Dolby.
  4. Select Off to disable Dolby.

Helpful tips:

  • Ensure the volume on the panel is not on mute.
  • Check if the cables are loose. Reconnect the HDMI cable between the panel and the media player.

  • Test with a different device such as a computer to determine if the panel's audio is functional.
