Mr Red -

One of the peculiarities of most of the Soundblaster cards is the "combined" input. You can select any single source for input; but if you want to mix more than one input, your only choice is the "what you hear" selection. You can usually turn off "everything you don't want," but many have wondered (aloud) why they haven't incorporated a better "selective mixer."

Not really to the point of anything - just an random observation.
