Having trouble with VOLUME? Check the controls on your Computer and Promethean Board to adjust volume first.
If those volume controls are at an Acceptable Level, check below for step by step (picture) instructions on how to fix this.
NOTE: THESE STEPS ARE FOR PROMETHEAN PANELS THAT HAVE THE OPS BOX INSTALLED INTO THE LEFT SIDE OF THE BOARD ONLY. THIS IS ALSO ASSUMING YOU ARE USING THE OPS BOX, AND NOT THE BUILT IN PANEL SOFTWARE. IF YOU ARE USING THE BUILTIN PANEL SOFTWARE INSTEAD OF THE OPS BOX, THERE IS A DIFFERENT "HOW TO" FOR THAT SETUP.
After Following the above steps, you should now have sound back on your Panel.
