Hallo, 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. Alexey
