This make me think there may be a kind of option in the the audio program/software preferences to chose midi / sound source.
Maybe a dropdown menu or settings icon to click?
It may also be that the PC preferences is set back to 'standard' soundcard when format and reinstall Windows,
and that you have to look into the properties to select correct audio source (KN2600) for recording.
