There are two of them, unintuitively enough; the one passed to the encoder should not be the one that gets written to the file. The former maps the input to an ordering which puts paired channels first, while the latter moves the channels to Vorbis order. So add code to calculate both, and we now have properly paired channels where appropriate. https://bugzilla.gnome.org/show_bug.cgi?id=665078
