Maybe too simplistic, but have you checked the audio coming out of the soundcard in the fault condition before it goes anywhere else?<BR>
If the crackling is there - regardless of heating/coolling/rebooting, then it's the soundcard.<BR>
We've found even the best and newest ones can suffer from poor joints.<BR>
If not, then it's happening after that and ,likely to be a connectivity/software/memory issue.<BR><BR>
