Try using other values.

Do you need to mix multiple signals into a single channel?  If not, try
using dshare instead:

pcm_slave.out_slave {
    pcm "hw:2,0"
    channels 36
    # ...
}
pcm.out1 {
    type plug
    slave.pcm {
        type dshare
        ipc_key 56874
        slave out_slave
        bindings [ 0 ]
    }
}
pcm.out2 {
    type plug
    slave.pcm {
        type dshare
        ipc_key 56874
        slave out_slave
        bindings [ 1 ]
    }
}
