sounds like you're preamping it too high before it goes to the speakers.
if you have some sort of graphical equalizer, you can tune the sound to
be correct. Play a "loud" sound while tuning teh volumes of your
equalizer (not the speakers), and keep tweaking until the volume never
hits the maximum.
The "forced" sound is usually caused by the amplitude of the wave being
cut off as it reaches the limit forced on it by the hardware. By
reducing the strength of the amplitude, you're reducing the chance that
it'll hit it's limit.
