Hi,

I've made a test-case in the form of a simple C program which generates 10 sec 
of 440 Hz sinus. With a define, it can generate samples at 44.1 kHz or et 48 
kHz. Direct output at 48 kHz sounds perfect but output at 44.1 kHz through 
the alsa rate plugin clearly shows a problem generating high frequencies.
I've attached the test case to this mail. It can be compiled with:
gcc -lasound alsatest.c -o alsatest
Please chane the samplingRate define to test with 44100 and 48000

Thanks, have a nice day,

Steph
