Raymond I have done that. Also today I was able to test an Asus Xonar U7
but the edition of the card which is not the Echelon edition. I believe
the two cards are the same hardware but the echelon edition had
additional Windows software included and for some reason Asus decided to
change the USB name
This non-Echelon version presents itself as "Xonar U7" to alsa and
adding '"Xonar U7" 1' to USB-Audio.pcm.iec958_device appears to work as
aplay -L | grep -A 2 iec958
reports
iec958:CARD=U7,DEV=0
Xonar U7, USB Audio #1
IEC958 (S/PDIF) Digital Audio Output
I still wasn't able to play directly from it - I guess I need to do
further work in pulseaudio too. I can't test that as I only had the card
on loan but will progress this once alsa-devel have a fix for the '.' in
my own Echelon 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.
