i played a bit with pa and have question:
I know pa will resample stream if my src use 44100Hz and my sink need
16000Hz, so it take some cpu (~10%) time. Why it take so mach CPU even
if src and sink are same? On play back with sink=src pa almost not use
cpu, why on record?

And one more question: are there any way to have multiple default rates?
My sound card support 32000,44100,48000 ... and i think it's really sad
if pa resample 48000 down to 44100.. it's more about cpu, not quality.
