Just finished new build of QMX 20 to 10.? But no control of volume?? Its volume is full, can not adjust it?? Checked connections several times, all connections on the pot on both top of board and bottom of pot have connection to the header pins, none are grounded out.? Adjusting the dB setting for audio in menu changes volume, so at 80 dB no sound and at 0 dB very loud.? Any help or suggestions would be greatly appreciated.? Thank you? 73? Emory? WM3M
