I used to be able to use the optical SPDIF input for this device from my
synth, but that seems to have stopped working. Further, I can't play
audio out of the Sound Blaster HD's optical SPDIF output, either. It
works in Windows 10, which is where I had to spend my latest music
session -- yuck.
Exactly what does 'stopped working' mean? Doesn't it should up when you
enumerate audio devices, does it show up but input and output results in
silence, does it show up but attempting to send audio results in an error,
etc. (I know you linked to a long ALSA dump, but folks around here would
be more willing to help if you stated as precisely as you could which
symptoms you actually have.)

Sorry for being asleep at the switch, tax time hit me squarely between
the eyes. :/
The problem I'm seeing is that pulse can select the spdif input on both
devices, but I never hear any sound. I've also tried using alsa via rec
(from SOX) to record from various hw: devices with no joy. Also using
ALSA devices from Audacity (which is what I started with in the first
place.)
HOWEVER, I was able to get at the optical audio in on the SIIG device
with the following command:
arecord -c 2 -f S32_LE -r 48000 -D dsnoop:CARD=Audio,DEV=1 trythis2.wav
And then I investigated the "plughw" interface, and this worked too:
arecord -c 2 -f S16_LE -r 48000 -D plughw:CARD=Audio,DEV=1
trythisPLUG.wav
So at least I can investigate that, and read up on using dsnoop and
plughw devices with Audacity.
The Sound Blaster HD, though, didn't have the same luck -- it is still
flatline when I view the dsnoop: device recording .wav files with
audacity, as well as the files from arecord on the plughw devices.
The output of arecord -L is in my .sig.
I see also "dmix" devices on the SIIG device, I will now investigate
those for optical spdif playback on the SIIG device, and the Sound
Blaster HD device if I have a chance. The X-Fi device plays through the
optical spdif connector as expected.
Thank you!
