Recently hooked up my decks to my pc in the hope of being able to record some of the tracks i have, just when i plug it in the audio plays fine through my speakers from my decks, but when i try to record it, it doesnt record anything so i've tried changing the recording source just to see what happens and i loose all audio from the line-in if i set it to line-in or a few others, if i have it on CD-Audio or Microphone it works but then doesnt record anything as its trying to record the wrong source. any help?
