(1) hdsploader has nothing to do with "firmware" although people often use
that term. What is loaded is actually configuration data for the Xilinx
chip, mostly to set up the matrix mixer
(2) the device driver will load the "firmware" itself automatically. The
only time hdsploader is useful these days is when for some odd reason you
need/want to force a reload without rebooting.

hdspmixer is modelled on RME's own TotalMix and you should visit their
website to read up on how it works (newer versions of TotalMix are a bit
different, however). It isn't a particularly intuitive design, but once you
understand it things will be much more clear. remembering that clarity can
be hard, depending on your age and aptitude.

no.

and by the way, using amixer is not horrible. I have this little script
which i used to use to configure my Digiface. It is really useful and much
faster than firing up hdspmixer and loading some preset.

 #!/bin/bash

AMIXER="amixer -q"
CARD="-c 1"

if [ x$1 = xon ] ; then
    gain=32768
    verb="route"
else
    gain=0
    verb="mute"
fi

shift;

#input_source : 0-25  (physical channels),
#               26-51 (software playback)
#output_source : 0-25 (physical channels),
#               26-27 (line out)

    for chn in $(seq 26 51);do
        $AMIXER $CARD cset numid=5 $chn,$(($chn-26)),$gain
    done
    ;;

    thru)
    for input in $(seq 0 25);do
        for output in $(seq 0 25); do
        if [ $input != $output ]; then
            $AMIXER $CARD cset numid=5 $input,$output,$gain
        fi

        if [ $(($chn % 2)) -eq 0 ] ; then
        $AMIXER $CARD cset numid=5 $chn,26,$gain
        else
        $AMIXER $CARD cset numid=5 $chn,27,$gain
