The M-Audio site provides no specifications for either the Fast Track Ultra or the Fast Track Ultra Pro. The Fast Track Pro is specified as 40dB gain. The lack of audio specifications for the USB 2 devices seems rather suspicious overall. I would guess that the preamps in your soundcard are the lower gain type. The mixer may have higher gain preamps. The difference would be quite easily noticed.
Another "feature" that is very common until you get to serious money is the use of linear potentiometers as gain controls rather than the inverse log ones that should be there. The gain is linear but our perceptions, and the dB scale, are logarithmic. The result of this is that the perceived gain is mostly in the last few degrees of the control’s movement. As you turn up the gain knob, you gain a little loudness, a little more, a little more, then suddenly the major part of the gain (as measured in dB) kicks in over a very small range of rotation. This saves about 25 cents per unit manufacturing costs.
I'am using Windows XP Pro and either Adobe Audition 2.0 or Camtasia Studio that I use for making video tutorials. The store I returned the Fast Track Pro did a internet search and found similar problems listed in various forums but no fixes.
