I think the audio card is working.
The problem is in the way the motherboard and case are wired.
The front digital audio port traces to SPDIF_IN (pin 17 of the 18 pin
"Front Audio Pin Connector"), which means this can only accept
Optic-Digital-IN.
The only SPDIF_OUT appears on pin 57 of the 80 pi
I'm concerned because http://alsa.opensrc.org/DigitalOut example shows
'cat /proc/asound/devices' with a unique hw:x,y for the "digital audio
playback" device, and my output shows:
16: [ 0- 0]: digital audio playback
17: [ 0- 1]: digital audio playback
and neither of these work:
aplay -D plughw
I've found a script for helping to debug.

Am I having a syntax problem with aplay?

I got a little farther.

I think I need to send output to hw=0,1 but it still doesn't work.
What am I doing wrong?

I need help to play optical-audio out from a pico-itx px1g in a
Serener GS-L08 case (which has an optical-audio connector).
I connected a Klipsch 5:1 system to the pico case via a standard
optic-audio cable.
Then I tried aplay and play to send sound out the optic port, but have
had no succes
