I have my doubts too about connecting the speaker output to the
sound card the way you have mentioned.  However, my old
soundblaster 16 did have a set of pins for connecting the case
speaker wire to the sound card (and it is infact marked
PCSpeaker). I don't recall seeing this on my newer SBAWE or
other sound cards.  So it doesn't hurt to look.  The pins were right
next to the cdrom audio in connector.
