Your best bet is azalia(4), i.e, it needs to be supported by the
motherboard.

There are uaudio(4) devices with SPDIF output, however there you
may run into issues with our USB support and audio devices.

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.

Correction, it's an E17k. The E17 should work too, though.

 I have an FiiO E17 that works out of the box on OpenBSD, and it has
coaxial spdif input.

ok, answered my own question by grep'ng within /usr/share/man/man4,
looks like azalia(4) systems.  Was hoping for something usb attached

supported Audio card with SPDIF input

2018-07-24 Thread Diana Eichert

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?

thanks
