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.
