You can only use one or the other. They both go to the same input slots. They just have different input levels I think. I have read online that you really don't want to use the mic input on most cards because it is usually noisy. If you want to get a decent multi-input card for Linux the best choices (that don't cost a fortune) are the M-Audio Delta 44, 66, and 1010LT.
