In general, Line Out 1 is normally Line Out, when it output digital signal, it will be change to SPDIF Out automatically (see page 47 for more information). Line In: In general, Line In is normally Line In. When you select "Four Speaker" in Creative application (see page 45 for more information), Line In will be change to Line Out 2, then you can plug 2 pairs stereo speaker into Line Out 1 and Line In simultaneously.
