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.
dmix does 48 kHz by default. Does it sound "awesome" when you play a 48 kHz file directly to hw:0,0? If that also clicks, the problem will be your driver's handling of the 48 kHz rate -- if not, it'll be the resampling, and I'll probably need to bow out...
