Your test demonstrates that 1.8 changes are required to cause the problem, but clearly SDL is involved, otherwise why would waveout solve the problem as well? If possible, a test of pygame 1.8 against the 1.7 SDL versions could still help solve the case.
maybe in order to figure out what pygame 1.8 change made the crackling start happen, you could binary search against svn revisions? i.e. if pygame 1.8 was rev. 1200 and 1.7 was rev 600 (made up numbers) then try rev. 900?
