Speaking of making the problem worse, using the p4fftwgel2 package, which is optimized for
P4, makes CPU usage *higher*. I'm not even kidding.
But, and even more strangely, it seems to also makes the crackling a little better, even
though CPU usage is higher. It's as if it allows the CPU usage to go to higher levels
before failure, but itself takes up more CPU.
I'm completely baffled as to why this is.

for Xorg
This might make the problem worse. Many graphics cards are mean to the
PCI bus. The extra interrupts can make latency issues worse.
What version of fftw is being used on your system? If you're using
fftw v2, make sure to build it for your arch! If you're using fftw3,
arch specific SIMD is automatically used by the lib.
