not using 44100 as the init value was my mistake.

i am going to the trouble of manually converting it now to see if that 
fixes the problem.  i normally assume using a library to do what it 
does, the proper way.  hopefully, manually resampling will fix the 
problem.  i'll see and let everyone know.
