ok, answered my own question by grep'ng within /usr/share/man/man4,
looks like azalia(4) systems. Was hoping for something usb attached
but no such luck.

I'm trying to connect to an audio system that only has SPDIF output.
I looked at man pages but nothing obvious regarding supported audio
devices with SPDIF input support.
Anyone have recommendations? Or is it supported?
Very broadly speaking, as long as the USB device conforms to the USB
Audio Class spec, it doesn't matter whether it's got S/PDIF or Coax or
2xRCA or XLR - audio waveforms should still get transferred from PC to
output.
What I think you might lose is any sort of decent mixer control,
although with S/PDIF I expect you might not really care about that?
Caveat: I have not personally tried a USB-to-S/PDIF audio device, but I
*have* read the specs and the datasheets. In theory, theory is the same
as reality...
Best-case, a USB SPDIF output device would a) conform to the USB Audio
Device Class interface, and b) report that it has no adjustable mixers,
so that on the software side, the mixer doesn't get confused.
