The following .asoundrc works for me to route stereo sound simultaneously to digital and analog output. Doesn't work for 5.1 sound sources though.

Code:
pcm.!default {
  type plug
  slave {
    pcm multi
    rate 48000
  }
  ttable.0.0 1.0
  ttable.1.1 1.0
  ttable.0.2 1.0
  ttable.1.3 1.0
}

pcm.stereo {
  type plug
  slave {
    pcm multi
    rate 48000
  }
  ttable.0.0 1.0
  ttable.1.1 1.0
  ttable.0.2 1.0
  ttable.1.3 1.0
}

ctl.stereo {
 type hw
 card 0
}

pcm.multi {
  type multi
  slaves.a.pcm "analog-hw"
  slaves.a.channels 2
  slaves.b.pcm "digital-hw"
  slaves.b.channels 2
  bindings.0.slave   a
  bindings.0.channel 0
  bindings.1.slave   a
  bindings.1.channel 1
  bindings.2.slave   b
  bindings.2.channel 0
  bindings.3.slave   b
  bindings.3.channel 1
}

ctl.multi {
 type hw
 card 0
}

# Alias for analog output on the nForce2/4 (hw:0,0)
# - This is identical to the device named "default"--which
# always exists and refers to hw:0,0 (unless overridden)
# - Therefore, we can specify "hw:0,0", "default", or "analog"
# to access analog output on the nForce2/4
pcm.analog {
 type plug
 slave.pcm "analog-hw"
}

# Control device (mixer, etc.) for the nForce2 card
ctl.analog {
 type hwplug
 card 0
}

# Alias for (rate-converted) mixed analog output on the
# nForce2 (hw:0,0)
#  - This will accept audio input--regardless of rate--and
# convert to the rate required for the dmix plugin
# (in this case 48000Hz)
pcm.mixed-analog {
 type plug
 slave.pcm "dmix-analog"
}

# Control device (mixer, etc.) for the nForce2 card
ctl.mixed-analog {
 type hw
 card 0
}

# Alias for (rate-converted) digital (S/PDIF) output on the
# nForce2 (hw:0,2)
#  - This will accept audio input--regardless of rate--and
# convert to the rate required for the S/PDIF hardware
# (in this case 48000Hz)
pcm.digital {
 type plug
 slave.pcm "digital-hw"
}

# Control device (mixer, etc.) for the nForce2 card
ctl.digital {
 type hwplug
 card 0
}

# Alias for mixed (rate-converted) digital (S/PDIF) output on the
# nForce2/4 (hw:0,2)
#  - This will accept audio input--regardless of rate--and
# convert to the rate required for the S/PDIF hardware
# (in this case 48000Hz)
pcm.mixed-digital {
 type plug
 slave.pcm "dmix-digital"
}

# Control device (mixer, etc.) for the nForce2 card
ctl.mixed-digital {
 type hw
 card 0
}

# Control device (mixer, etc.) for the nForce2/4 card
ctl.dmix-digital {
 type hw
 card 0
}
