Hi,

I'm trying to work out how to record from an S/PDIF input
using a Terratec 7.1 Space (Envy24 based card, supported by
ICE1724 Alsa driver).  I simply can't work it out.

Under Windows it's necessary to use the Terratec control
panel to select S/PDIF as the recording source (rather
than the analogue mixer/sources).  What I think I should
do under Linux is something like:

$ arecord -f dat test.wav -Dhw:0,1

This gives:

Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo

arecord: set_params:901: Sample format non available

$ arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: T71Space [Terratec Aureon 7.1-Space], device 0: ICE1724 [ICE1724]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

card 0: T71Space [Terratec Aureon 7.1-Space], device 1: IEC1724 IEC958 [IEC1724 IEC958]

  Subdevices: 1/1
  Subdevice #0: subdevice #0

While you're waiting for a real reply, try this ...

arecord -L

Should show a list of PCM device names, on my box, I see "spdif" and "iec958" in the list.

arecord -f dat test.wav -D spdif

might work, I don't actually have a working spdif input.

Thanks for the suggestion.  This gives the same 'non available'
error as above.  Maybe these aren't recording aliases?

Contents of 'arecord -L' are attached.

I've just confirmed that an analogue loopback recording works
if -D is not specified, whereas -Dhw:0,0 (which I think should
be the analogue device) gives the 'non available' error.
