You could try to set up an environment variable before starting snd to 
point to that particular device. This is the way snd reacts to env 
variables:

- searched for in the following order:
  SNDLIB_ALSA_PLAYBACK_DEVICE
     defines the name of the playback device
  SNDLIB_ALSA_CAPTURE_DEVICE
     defines the name of the capture device
  SNDLIB_ALSA_DEVICE
     defines the name of the playback and capture device
  use the first two if the playback and capture devices are different or the
  third if they are the same.

So you could try:
  SNDLIB_ALSA_DEVICE="hw:0,2" snd
if you are using bash as your shell

This should use the digital i/o as the input output device.  It would also
be possible to concatenate several devices using a definition in the
.asoundrc file but that would involve understanding its arcane
configuration language, which I don't. The current snd alss 0.9 code only
looks at the first device it finds (normally hw:0,0).
