Setting nchannels to 2 has ABSOLUTELY NOTHING TO DO WITH THE B SIDE,
it has to do with receiving 2 DDC streams.

I suggest that Max ensure that he's looked at the inherited python
code in the daughterboard hierarchy.  He may be using the wrong i2C
address or something similar.  Is the rx mux set up properly to route
the samples from the B side A/Ds into DDC 0?
