I think it would be important to determine where the crackle stems from.

Is it caused by xruns or possibly RF like Paul suggested.

I sometimes tend to get a little bit of RF noise with my external USB
soundcard as well - need to experiment with grounding, possibly.

Other than that I have less trouble with the Intel onboard graphics on
the laptop than the dedicated Radeon graphics (with open source
drivers) on the desktop.
