    slaves.b.pcm hw:3
    slaves.b.channels 2;
    bindings.0.slave a;

    bindings.1.slave b;
    bindings.1.channel 0;
    bindings.2.slave a;
    bindings.2.channel 1;
    bindings.3.slave b;
    bindings.3.channel 1;
}

ctl.Maudio {
    type hw
    card 1
}
Start JACK with the following command line: /usr/bin/jackd -R -dalsa -dhw:Maudio -r44100 -p128 -n2 -Xseq
I created the .soundrc file with the contents you posted, then issued the start command for jack (had to change -dhw:Maudio to -dhw:M2496, which then produced the following.

It still doesn't make the second card accessible in REAPER though. I also tried modifying the .asoundsrc file so that the referenced names in it at the top and bottom were M2496, but that didn't make any difference either.
