That's not really the "sound board". Most system 11 sounds some from the sound section on the main board. That smaller board only provides the background ("B/G") music. You can disconnect it and (and may need to move the volume control from 11J2 to 1J16) to see if the problem goes away. That will at least isolate the problem to either the sound section of the CPU or the B/G sound board.
