The hardware was kept as close to Harmony as possible on purpose in
order to reduce the time needed for customization. This is obviously no
longer true now because the hardware is already about 18 months old but
you can't change hardware retroactively...
Again I'll make sure to double check this against the schematics but I'm
pretty sure these are the connections.

Would you mind explaining why it is broken? I haven't really been
involved with the codec parts so I don't have very deep insights.
