Not familiar with the 2044. I assume you have some sort of metering when recording so you can get a good signal to hard disk? If you have a strong signal at that stage (-5 to -1dB)the problem isn't there. Within Cubase, the fader for the track you recorded on is 3/4 of the way up or so. Also, check under the tabs Audio, Master, make sure those stereo faders didn't get pulled down somehow.
All I can think of for now.
