A sound card cannot tell the difference between low level sound and high 
level thermal noise.

When you hold a sea shell to your ear, you are hearing thermal noise, 
and the only reason that you do not hear thermal noise all the time is 
that you subconsciously filter it out.   The sea shell changes the color 
of the thermal noise, thus bringing it to conscious awareness.

So, if a sound card cannot pick up thermal noise, user will perceive it 
as a shitty sound card.
