Things to try

Test pulseaudio with aplay to get a baseline
you want to hear the crackling with aplay->pulseaudio->alsa->your speakers

Then try aplay->alsa->your speakers
If the crackling remains then the problem is not pulseaudio

Try another sound card.
use `aplay -l` to see if you already have two or more.
For example I have two soundcards in my computer the builtin one for my
headset and my speakers are connected to my monitor which is connected to
my computer via hdmi.

If you get stuck you could try the #pulseaudio irc channel.
