Autotune Clicks and Pops solutions?

[SWBoatman25]

Hello, I have Autotune 8.1

I have recorded a vocal track, then I insert the Autotune plug in to clean up anything out of whack.

After tracking the pitch, I listen to it in playback and there is always a crack or a pop somewhere in the vocals.

I only have a EQ on the track and bussing it to a de-esser. Not much goin on in terms of plug in use on the track (1-autotune. 2- de-esser. 3- EQ)
I have not shifted or moved the clips around, I have only added fades.

Has anyone had this problem and can solve it?

I have:
Mac OS X El Capitan 10.11.1
Pro Tools 11.1
Interface: Focusrite Scarlet 2i2 (2 yrs old)

Playback engine is at: 1024 samples
CPU usage fluctuates at around 30%


Thank you
