Some info which may be of use.

Capture assignments are fixed:

   1..8 : analog inputs
   9..16 : ADAT input
   17,18 : SPDIF input

Playback channels go via the matrix mixer. You either have to use
hdspmixer, or a script like this one:

----------------------------------------->8------------------------------------
#!/bin/bash

# mixer inputs:
# -------------------------------
# 0-7 analog in
# 16-23 adat in
# 24-25 spdif in
# 26-33 playback 1-8
# 42-51 playback 9-18

# mixer outputs:
# -------------------------------
# 0-7 analog out
# 16-23 adat out
# 24-25 spdif out
# 26-27 headphones out

# Alsa device name
device=hw:DSP

# 32768 is 0 dB
gain=32768

function set_gain ()
{
    amixer -D $device cset numid=5 $1,$2,$3 > /dev/null 2>&1
}

function reset_matrix ()
{
    for out in $(seq 0 27); do
        for inp in $(seq 0 51); do
            set_gain $inp $out 0
        done
    done
}
