You mean probably 44.1kHz.. Unfortunately Sample Rate Converter from
ES1371 isn't very much documented and I simply copied code from driver by
Thomas Sailer (it's a part of sound driver in latest 2.1.x kernels - check
drivers/sound/es1371.c code - routines are marked as "black magic"). Maybe
there are some typos, so you can verify my code at first. I don't have
ES1371 soundcard to test it...

This bug shouldn't be in aplay / arecord - with other soundcards these
programs work properly..
