Add a bit more dither to make the mid level voltage acceptable through the sigma delta, since it now sits a 2.5v for silence (internally, external is ac coupled). This fixes the sample engine clicks when playing mod files due to the sample engine volume being applied on unsigned converted samples, which gave a dc bias betwen samples. Paula samples have to end/start at signed midpoint you see.
