It is. I removed those simple mixer controls because I could find no 
proper way to deal with them while changing speed mode.
Anyway, anything you could do with those you can do either with 
hdspmixer or amixer in console mode, using the 'Mixer' ctl.

The amixer syntax is as follows :

amixer -c X cset numid=5 in,out,level

Where:
X is your alsa card number
0  <= in  < 26  : physical inputs
26 <= in  < 52  : playbacks (software outputs)
0  <= out < 26  : physical outputs
26 <= out <= 27 : line outs (phones), if any
0  <= level < 65536 : gain (65535 = +6dB, 32768 = 0dB)

(H9632 users should read :
0  <= in  < 16 : physical inputs
16 <= in  < 32 : playbacks (softwre outputs)
0  <= out < 16 : physical outputs
)

Here's an example :
amixer cset numid=5 26,0,32768
amixer cset numid=5 27,1,32768
This routes software outputs 1/2 (playback_1 and playback_2 in jack) to 
physical outputs 1/2 with a 0dB gain.
It is the same as formerly setting the level to 50% in the first 2 
alsamixer strips.

Below is a small script that does the same as the first hdspmixer preset 
(for non-h9632 cards, and assumes the hdsp card is the default one) :

#! /bin/bash

for out_left in $(seq 0 2 25);
do
let out_right=$out_left+1
let in_left=$out_left+26
let in_right=$out_right+26
amixer cset numid=5 $in_left,$out_left,32768
amixer cset numid=5 $in_left,26,32768
amixer cset numid=5 $in_right,$out_right,32768
amixer cset numid=5 $in_right,27,32768;
done;

I know this problem, but didn't find a solution yet. For some reason the 
specified wait time isn't always respected, so even if the firmware has 
been correctly uploaded ('host' light turns off on the io box), the 
function returns too early with an error, and the initialization process 
in stopped (the alsa pcm and midi devices are not created). Running 
hdsploader a second time usually fixes this.

I have nothing special in my modules.conf, I usually run hdsploader by 
hand. You may use the above script to set the levels up.
