Helpful tips:

  • Ensure the volume on the panel and the computer is not on mute
  • Check if the cables are loose. Reconnect the HDMI cable between the panel and the computer
  • Swap the HDMI cable to eliminate a faulty cable
  • Test with a different computer to determine if the issue lies with the original computer
  • Run the Windows troubleshooter for the audio
    • Under Type here to search, type Troubleshoot and select the best match: Troubleshoot System Settings
    • Find Playing audio and click Run the Troubleshooter
  • If you are using a VGA cable, please connect a 3.5 mm jack from the computer to the panel as  a VGA cable will not provide sound
