I get a crackling sound when I use my cross fader going from A to B side.
I tried increasing my latency all the way up to see if that was the problem and I still was getting the clicks.

Any ideas on what the problem is???

Is your master out meter going into the red?
Depending on wich CFcurve you are using both signals are added together and can cause clicks due to clipping.
Try a different CF curve or lower the levels on both tracks by -1or2dB.

I get the same problem with Live 6.0.7.
Doesn't happen if I use the channel faders and it happens even if I fade from one playing clip to another channel with silence. I think it's a bug, because I get it on two very different computers.
