What's the point of that? Why would Apple make a lossless compression format that their own music software can't rip accurately? The whole purpose of a media server program ripping lossless files is to do so from an original CD, not to have to make a WAV file first with different audio extraction software.
Yes, you could be correct. Perhaps it's not the codec, perhaps it's iTunes itself. But since ALAC is a propietary Apple format and iTunes is their propietary media management software, if neither one of them work properly it is pointless to use that compression format.
