Hello LAUs,
maybe someone here knows how I can record from an ICE1712's Monitor
Mixer using ALSA? I routed the HW in 1/2 to the digital mixer in
envy24control, and now I want to record that, but I'm perhaps just too
stupid to find out how the monitor mixer is called in ALSA.
That device is R/W for sure:
http://www.alsa-project.org/alsa/ftp/datasheets/icensemble/envy24.pdf
Using 4Front's OSS (not the in-kernel) it is as simple as recording
from /dev/dsp4, which is the monitor on my audiophile 2496. But OSS is
a pain when trying to use jack or any recording app like rezound or
audacity with it. This somehow must be possible using ALSA too, not?
I also tried using ALSA's jack plugin, and record with jack_capture, but
a) I get total sound distortion as soon jack_capture starts, and
b) that's one layer too much anyway, as the card can do "loopback"
itself. So i'd prefer ALSA.
Any help would be appreciated.
Thanks,
Tom

I'm curious about this, too. For recording from my
ICE1712 based DSP3000/DSP24 I use this format:
s32_le,12,44100,i (12 channels of 32 bits, interlaced)
In my case that would be 8 channels of XLR
inputs, 2 channels of SPDIF; the final 2 channels
I believe to be the mixer out. But I've never
succeeded in recording these last two channels.
Usually I just do the mixing in Ardour or Ecasound.

The Monitor Mixer outputs should be available as inputs 11 &
12.

Hmm, looking at the envy24 datasheet, yes (that says something about

How do I access those using arecord for example?
I could imagine something like "monitor" in aplay --list-pcms, but
there is nothing like that. Maybe I have to create and assign them
first?

This page describes setting up and asoundrc with separate devices for
different channels. You can then point arecord at one of these devices:

Bingo! Thanks guys for slowly pointing me to the right direction.
This + a stumble over http://alsa.opensrc.org/1712_.asoundrc#2003-09-18
lead to this:
pcm.ice1712 {
type hw
card 0
device 0
}
pcm.monitor {
type plug
ttable.0.10 1 # digital mix left
ttable.1.11 1 # digital mix right
slave.pcm ice1712
}
Et voila 'qarecord --device monitor'
Cheers,
