Are you all running Windows ?
If so, then I've seen this before and this problem has nothing to do with your controllers, mouse or Live, it's all down to IRQ sharing in Windows XP.
Video cards, hard drives, ect usually get their own IRQ in XP but audio cards (PCI, usb and firewire) for some reason are lumped into the 'Other devices' category and often onto the same IRQ as other devices like mice, even QWERTY keyboards and controllers, so when you move a control/mouse the data flow from your card is interrupted and you hear a crackle.
It's pretty common, used to have this problem on my old PC with a PCI Emu 1212m
You can find out what is sharing IRQ's by going to
System Information > Hardware Resources> IRQ
Solving it is sometimes tough, on a desktop pc you can keep changing the PCI slot your card is in, and keep booting in different configurations till you find one where you audio card is sharing with nothing (if your lucky) or something which you can easily do without or disable. Switching USB ports on a lappy may have the same effect but I'd say only if they are in a different physical location (i.e. left and right on a lappy), I've never tried this though but worth a look.
On a laptop you need to disable anything you don't need, card readers, wireless networking, wired networking, integrated webcams ect reboot and hope your card is sitting on its own IRQ, if you've exhausted every option you can edit the IRQ configuration manually but this is NOT recommended and you may have problems down the road as XP likes to manage IRQs itself and can throw a wobbly. If you do go down this road be sure to read up before you try it.
XP can see different controllers differently and put them on different IRQ's, that's why people changed controllers and the problem went away, there was probably nothing wrong with your controller.
Any questions let me know.
Hope this helps.
edit: I'm thinking the Live 7 CPU spike issue, linked to in this thread, is a different issue to the one I and johnisfaster have described. This issue relates only to crackles when moving controllers/mouse, not cpu spikes.
