1.1.1. Note that there is no problem in *playing* files with audacity.

Ah yes, there is one on my one, too. Seems that I typed something
wrong?! But man does not really provide more information than --help (at
least in version 0.9.0rc7). :-(

Well, -f S16_LE -r 48000 -c 2 is identical to -f dat and actually also
results in a mute file.

In the meantime I checked modules.conf by the great c't article of Frank
Barknecht. Everything seems to be okay there. But I could not find
/etc/asoundrc or ~/.asoundrc. May be this is the reason for my problem -
I am going to find out next.

Yes, arecord seems to be exactly what I need for a 1:1 DAT copy.
Nevertheless I still can only record mono files with definitely much
lower level than the input signal (which takes the full range of the
envy24control meters). Moreover I found out that xmms and audiacity play
it a bit faster and higher than the original data, even though I always
use the DAT's master clock! :-(

By the way: Does anybody know, what HardwareSettings -> VolumeChange
means in envy24control?
