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
Hi!
These are just ideas, I really don't know for sure. But maybe it helps...
Try wrapping your devices in plug-devices like this:
pcm.plug_player {
type plug
slave { pcm "audio_player"
}
Or try to remove the ctl-devices. With aplay and other good alsa-programs
they shouldn't be necessary

I am using a 4-input, 8-output codec (AD1938) in an application
similar to a live sound mixing
board, where a combination of the input signals get mixed for each
output. I can mix four
inputs to four outputs with a command like:
arecord --file-type raw --channels=4 --format=S32_LE --ra
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
