Our software sees the sound coming from the "sound output" in the window "Sound Settings" of the Operating System.
This means, in this window, you have to define which audio signal (microphone, internal player, jack 3.5 input, ...) you want to see in our software.
There are a bunch of tutos telling how to configure audio in and out.
