Bug#720767: pulseaudio: Crackling sound on startup until module-suspend-on-idle kicks in

I've also had crackling and popping problems with pulseaudio ever since
I started using it about a year ago.
I've got a regular Intel sound card in an Ivy Bridge laptop.

After about a year of ripping my hair out, I finally tracked my problem
down.

/etc/pulse/default.pa

Try setting
load-module module-udev-detect tsched=0

Then rebooting.

That completely fixed it for me and it's been weeks and I haven't heard
a single crackle or pop.   I was hoping if you could give it a try and
report back to see if that was your problem as well.  It looks like this
is a very common problem.
