I'm far from being certain (20% sure) but I think codec_dahdi relates to
Digium transcoding cards (G729 to A/U LAW).

My understanding is that current default and implicit installation policy is
to have those cards enabled and running without any user action which make
those error messages appear on systems not including those cards.

I would be very happy if someone could correct this explanation and shed
some light about what this is all about ...
