Looping craking noise on Cross 2.0.1

Hi,
As an (might say advance user) of mixvibes, i play only with mixvibes at big parties and my regular residency...i find or whether a bug or a lack of a good computer on my set
Ok when i press auto loop on a fly sometimes not always but mostly i hear a crack noise on the sound, did i'm doing something wrong or other users have the same issues?
By the way i play mostly in vinyl timecode, and my external controllers are a traktor x1 2 hercules an lpd 8...but in the main set i use de x1,
