i have had my US tucked away for a few months cuz i was going to re-work the wires. and after puting everything back on the board (9v conectors) i put a fresh 3.7Li-ion in hit the switch and the led turnd on but no sound. it worked when i put it away but now idk i have tryed 3 diffrent speakers one was brand new out of the box from TCSS. main led turns on accent leds work but no sound so im about ready to shoot myself in the foot over this errg
