Is the accuracy of a sound card really so bad?  Even the cheapo sound 
card I just took out of my PC has a 24.576MHz crystal which divided by 
512 is exactly 48kHz, so surely a 440Hz sine wave through a PC sound 
card will be spot on.  I can't believe there are sound cards that play 
your music out of tune!
