Did you check that the proper input (line-in ?) in your
sound card, is set to RECORD as reported by your mixer ?
The fact that you hear the sound in the speakers is not 
enough (it simply means that the sound is passed through
in the sound card's preamp), to capture the sound in the PC
you must use your mixer to set the input to recording mode.
