All authors have agreed to the relicensing. The code was pretty much rewritten by Stefano Pigozzi. Since the rewrite happened incrementally, and seems to include refactored portions of older code, this relicensing was done on the pre-refactor code do. The original commit adding this AO (as ao_macosx.c) credits Timothy J. Wood as original author. He was asked and agreed to LGPL. It's not entirely sure from which project this code came from, but it's probably libao. In that project, Stanley Seibert made some changes to it (who as a major developer of libao was asked just to be sure), and also Ralph Giles and Ben Hines made two small changes. The latter were not asked, but none of their code survived anyway.
