Right, which is why I'm saying this routing makes no sense.  You've got
code which has a mixer mixing input signals down into the DAC but what
you've actually got is a single output from the DAC which can then be
sent to the outputs separately.  You should be able to draw a graph of
the audio routes through the CODEC which directly corresponds to the
DAPM graph.
