Hi, When I play a 44Khz file without using any ALSA plugin like #aplay -Dhw:0,0 44k.wav the sound quality is awesome but when I play the same file using dmix, clicks are introduced. #aplay -Dplug:dmix 44k.wav changing period size and buffer size doesn't help. I am testing my ALSA driver on an OMAP850 based board. Regards, Pharaoh.
