Okay, got it now. The first way worked, the second way didn't. And
oddly enough, even after I changed slave.channels to 12 in
/usr/share/alsa/cards/ICE1712.conf, I can still play back. The
commands
# aplay foo.wav
# ogg123 foo.ogg
continue to work, but now this also works:
# arecord -f cd -t wav -D iec958 foo.wav
I recorded twice from the same digital source, to confirm that I was
getting a bit-for-bit copy, and it was exactly the same both times
(modulo head and tail noise, of course).
If you want, I can post more details about the failure of the
~/.asoundrc way; but I'll spare you the noise unless you ask for it.
Thanks for the help!
