I may be wrong but I have a feeling that the problem is in the 
pulseaudio actually not in alsa.
There's a thing called alsa-plugins-pulseaudio which creates virtual 
alsa device. This device sends all sound output to pulseaudio.
Many modern distributions like to use this device as default. And 
pulseaudio still has some crackling issues, yes.
