If I change that selection and make the input Mic, there's no problem, only that as it is a line signal, by beign amplified it gets distorted. I have actually two problems: the first and title for the post is that when I try to connect an audio device via the input jack of my computer, when the maxxxaudio3 box pop up and ask me if I wanna use the input as a Mic, Line or Rear out, I click on Line, because that's what it is, Cubase 5 doesn't get sound and only receivs the built in mic audio.
