no sound comes out , either through the speakers or head phones , when playing . singing . The track still records . This occurs whether I plug a " line in "at the back of the computer , e.g. guitar . or a micraphone at the front . If I play , " line in " , the top band of the moniter is dominant regardless of what I do to the pan . If I record with a microphone , both bands are equal , many thanks
