So I applied the patches (
http://lists.linuxaudio.org/pipermail/linux-audio-dev/attachments/20100817/d02f8aaa/attachment.bin
) by doing
'cat mudita24-1.0.3-patches-2/*.diff | patch -p1 --backup' in the
mudita-1.03 directory (
http://nielsmayer.com/envy24control/mudita24-1.0.3.tar.gz ) and it all
looks great and works nicely.
Seems much easier to control and snappier than 1.03, which seemed to
slow things down with the sliders (or the ALSA level callbacks) versus
1.0 version. Now it's back to feeling quick again.

The one regression I'm seeing versus the original 1.03 version: when
you move the sliders up and down in "Monitor Inputs" or "Monitor
PCMs", the dB labels change width going from -X.X to -XX.X (e.g.
"-9.9" to "-10.0" changes width). This width change propagates through
gtk so that if you do it on the left-most slider, all the other
sliders will jostle-around horizontally as you sweep the attenuator
downwards from +0.0 past -9.99 ... This is not happening on "Analog
Volumes" -- I think I solved this issue in the original code by adding
a space after the last decimal if the value > -10.0.

Nope, I've been waiting on your changes and doing other things.

I will test the Terratec DMX6fire next...

One other regression I noted is that with the -n ( --no_scale_mark )
option leaves some extra space in the "Analog Volumes" panel, compared
to the 1.03 version.

I also notice that in 1.03, I forgot to add verbiage for the "-g" (
--channel_group_modulus )option to the --help output.

Will test that along with the Terratec. Given how coarse the
ADC/DAC/mixer controls are to begin with, is there a way to set the
mouse scroll wheel to always increment/decrement the dB value by its
minimum step-size (e.g. 1.5dB for attenuator, 0.5dB for DAC/ADC)? Last
I checked, mouse-scroll incremented/decremented by two "clicks" --
whereas next/prev keys moved by one "click."

Looks good. I'm pretty happy with the resolution and actual gain
control provided by 0 to -48dB, but if you have something different in
mind, go for it...

I like the current level of granularity.

PS: Feature request -- have an "L/R gang" available on sets of inputs
in the ADC/DAC section where the size of the set is the "-g" value,
e.g. 2 by default for stereo. This would allow the option of changing
volumes on all channels of a multichannel setup simultaneously. a "-g
4" would allow, for example two groups of four channels, and a "-g 8"
would allow a single group of eight channels. Like the L/R Gang
control on the mixer, this control would be optionally enabled.
