The fact that it occurs with XP but not with 2000 or MacOS suggests
that there is something in XP that happens every minute that is
consuming enough CPU to cause an audio dropout (crackle).

If this is a fresh XP install, make sure that automatic Windows Update
is turned off and the virus scanner is disabled.  Sometimes there are
applications installed by the PC manufacturer that try to access the
net periodically to look for problems.  Look in the icon bar in the
lower right corner.  If you see "Bigfix" or something that looks like
a utility from the manufacturer, turn it off.

This site has a lot of helpful information about tuning an XP machine
for audio.

I don't do everything they recommend, but it is very important that
you turn off any background application that may access the network.

The other thing it could be is the video card driver.  Some video
cards share memory with the CPU which can cause problems for
audio devices.  Make sure you have the latest XP driver for
your video card.
