Windows Laptop Audio Troubleshooting:

  1. Ensure VGA + Audio OR HDMI is securely connected on both ends of the cable. HDMI carries video and audio through a single cable, VGA requires you to plug in the 1/8" (Headphone) audio plug. Do not connect VGA and HDMI at the same time!
  2. Turn volume levels to 100% in this order: Application (Youtube, Kaltura, etc.) - Computer (Windows Laptop Volume) - AV Touch panel
  3. Ensure the correct source is selected on the touch panel. Make sure Audio Mute is not engaged on the touch panel.
  4. Still having problems? Try using audio from another source (iPod, other computer, video player). This will eliminate the AV system/speakers as the culprit.
  5. If all else fails, restart the AV system using the touch panel, then reconnect your device after system cool down is complete.
