i also have m-audio 44, here's what i did: configure the track input and select M-audio line 1 or 2 or 3 or 4 (either Mono or Stereo), because usually, AA2's default settings of the line input is always the Windows settings, that is why you have to configure the settings and make it as your default. by making your setting default, once you will open a new session then your settings will be set up automatically. hope that helps.
