Just to sum it up:

For, at least, our two snd-hda-intel devices (ALC888 and 82801I (ICH9 
Family)) both position_fix values (POSBUF and FIFO, 0 and 3 
respectively) produce ok sound, only that

position_fix=0 makes alsa fine and jack crackle/sizzle
position_fix=3 makes alsa crackle/sizzle and jack fine

"alsa" meaning direct use of alsa and "jack" meaning (at least in my 
case) jack with the alsa backend.

Here I have alsa-1.0.14-31.2 and jack-0.109.2-0.pm.1 (0.pm.1 stems 
from the packman repository, I guess)
