Raymond thank you for your help.

 I am still having problems.

If I run aplay -l or use alsamixer my card is reported as "Xonar U7
Echelon Ed."

here's  the relevant part from aplay -l
card 3: Ed [Xonar U7 Echelon Ed.], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 3: Ed [Xonar U7 Echelon Ed.], device 1: USB Audio [USB Audio #1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 3: Ed [Xonar U7 Echelon Ed.], device 2: USB Audio [USB Audio #2]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

So I add

# number for the iec958 device can be changed here.
  USB-Audio.pcm.iec958_device {
         # "NoiseBlaster 3000" 42
         "USB Sound Blaster HD" 1
         "Xonar U7 Echelon Ed." 1

to USB-Audio.conf and restart audio with "pulseausio -k && sudo alsa
force-reload" and nothing changes

As before, pavucontrol shows "Digital Stereo (IEC958 Output)" as one of
the configuration options for card  "Xonar U7 Echelon Ed." but when I
select that option the card plays analog not digital.

So - either I need to do something else or I have the card name wrong.
How can I prove I have the correct card name?

Title:
  Asus Xonar U7 S/PDIF output not recognized by pulseaudio

Status in alsa-driver package in Ubuntu:
  New

Bug description:
  The external USB audio card Asus Xonar U7 is capable of both analog and digital output.
  ALSA name for the digital (S/PDIF) output is hw:1,1, and it is listed in aplay -l output, and aplay can output to it:
  aplay -D plughw:1,1 sample.wav. So, direct alsa sound works fine.

  However, pulseadio does not recognize the digital output of Xonar U7,
  it offers only analog output.
