The following (not tested) takes care of the routing. The multichannel
format depends on the sound card.

ecasound -a:1 -i:stereo-ab.wav \
                 -f:s32_le,12,44100 \ (for ice1712)
                 -o:alsa,4ch_device \
                                     \
          -a:2 -i:stereo-cd.wav -erc:0,2 -eac:0,0 \
                                -erc:1,3 -eac:0,1 \
               -f:s32_le,12,44100 -o:alsa,4ch_device

I wrote a utility to generate the routing code since
I could never seem to get my command-line options right.
