Actually, 48000 might be an improvement too.  A number of hardware/driver 
combinations don't do 44100 natively and the ALSA resampler leaves much to 
be desired.  Plus, you end up running resamplers on top of resamplers.

The word "crackling" keeps bothering me, though.  "Stuttering" is how I'd 
describe what happens when the machine can't keep up.  "Crackling" is 
something I associate more with clipping and aliasing and the like...gross 
discrete interference of some kind.
