Sorry, I should have included 'arecord -L' output in my previous post.
Here it is; the original post is at the bottom.

--- And the original message: ---
I have a M-Audio/Delta Audiophile 2496 card, running under Debian
GNU/Linux 2.6.0-test1 (hence ALSA 0.9.4, using ice1712). I'm trying
to record SPDIF input from a DAT player, to make WAV files on disk
(i.e., bit-for-bit copy).
Analog input is working fine:
$ arecord -f cd -t wav -D plug:hw x.wav
$ aplay x.wav
[ ... hear the music ... ]
$
(Much thanks to Clemens Ladisch for helping me to get that far!)
However, I haven't gotten digital input working yet; seems I'm missing
some configuration magic?
$ arecord -f cd -t wav -D plug:spdif x.wav
Recording WAVE 'x.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

Has anyone done this, with the Audiophile or any other SPDIF-producing
card? Is there some custom configuration I should put in my
~/.asoundrc? I've been Googling on the above (and various other)
error messages, but so far the suggestions I've seen haven't solved
the problem...
Thanks in advance for any pointers,
-Karl
