Thanks GideonX, AMB, subman, AndyHui. I got the card without a manual, and I could not find one at Creative's site. As for the symbols on the jacks, only the mic was clear to me.
I find these forums highly informative, and I value the opinions of users more knowledgeable than myself. It is unfortunate that certain members feel the need to make snide remarks or condescend others who are merely looking for answers.
