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
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.

Hello,
on my wife's ThinkPad running Ubuntu Gutsy (7.10) and ALSA 1.0.14 I
get no sound. But using the Gutsy live CD the sound works (and on my
desktop with the same sound chip (and Gutsy) but rev 01 instead of
rev 02 sound works, too)... It's
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
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 pin
