Thank you for all this help.

Is the problem with recording digital-in because both digital and analog
capture devices have the same identity (i.e. both are hw:0,1)?

Below, /proc/asound/card0/pcm1c/info is the digtial capture device, but
can it be referenced via a '-D' parameter to arecord.

cat /proc/asound/cards
 0 [VT82xx         ]: HDA-Intel - HDA VIA VT82xx
                      HDA VIA VT82xx at 0x9fffc000 irq 20
cat /proc/asound/devices
  0: [ 0]   : control
  1:        : sequencer
  4: [ 0- 0]: hardware dependent
 16: [ 0- 0]: digital audio playback
 17: [ 0- 1]: digital audio playback
 24: [ 0- 0]: digital audio capture
 25: [ 0- 1]: digital audio capture
 33:        : timer
cat /proc/asound/pcm
  00-01: VT1708 Digital : VT1708 Digital : playback 1 : capture 1
  00-00: VT1708 Analog : VT1708 Analog : playback 1 : capture 2

NOTE: I don't see a pcm device i can play from

ls -alF /proc/asound/card0

   dr-xr-xr-x 3 root root 0 Jan  8 08:23 pcm1c/
   dr-xr-xr-x 3 root root 0 Jan  8 08:23 pcm1p/

I need to reference either pcm0c or pcm1c, I think.
cat pcm1c/info
   card: 0
   device: 1
   subdevice: 0
   stream: CAPTURE
   id: VT1708 Digital
   name: VT1708 Digital
   subname: subdevice #0
   class: 0
   subclass: 0
   subdevices_count: 1
   subdevices_avail: 1

This is the analog capture device:
cat /proc/asound/card0/pcm0c/info
   card: 0
   device: 0
   subdevice: 0
   stream: CAPTURE
   id: VT1708 Analog
   name: VT1708 Analog
   subname: subdevice #0
   class: 0
   subclass: 0
   subdevices_count: 2
   subdevices_avail: 2

This is the digital capture device:
cat /proc/asound/card0/pcm1c/info
   card: 0
   device: 1
   subdevice: 0
   stream: CAPTURE
   id: VT1708 Digital
   name: VT1708 Digital
   subname: subdevice #0
   class: 0
   subclass: 0
   subdevices_count: 1
   subdevices_avail: 1
