    slaves.b.pcm hw:M2496_1
    slaves.b.channels 2;
    bindings.0.slave a;
    bindings.0.channel 0;
    bindings.1.slave a;
    bindings.1.channel 1;
    bindings.2.slave b;
    bindings.2.channel 0;
    bindings.3.slave b;
    bindings.3.channel 1;
}

ctl.Multi
{
    type hw
    card M2496
}
And then to start jack: /usr/bin/jackd -P80 -S -dalsa -d Multi -r44100 -p64 -n2 -Xseq

And if that doesn't work, try:
Code:
pcm.Multi {
    type multi;
    slaves.a.pcm hw:1
    slaves.a.channels 2;
    slaves.b.pcm hw:3
    slaves.b.channels 2;
    bindings.0.slave a;
    bindings.0.channel 0;
    bindings.1.slave a;
    bindings.1.channel 1;
    bindings.2.slave b;
    bindings.2.channel 0;
    bindings.3.slave b;
    bindings.3.channel 1;
}

ctl.Multi
{
    type hw
    card 1
}
And the same command line to start jack.

The first version would be the preferred one. If it works you should be able to put the command line back into the reaper prefs.

Can you confirm that "/usr/bin/jackd -R -dalsa -dhw:M2496 -r44100 -p128 -n2 -Xseq" starts JACK on the primary card, and "/usr/bin/jackd -R -dalsa -dhw:M2496_1 -r44100 -p128 -n2 -Xseq" on the secondary card?
From the other post, yes both those commands fire up jack as expected, and the typo was indeed a typo.

Both variations of the newest .asoundrc generated the following.
