Summary:                    no digital output
Description: 
Shortly: Digital output doesn't work at all, or I don't know how to use
it.

This has been my problem quite long time now. I have upgraded my kernel
from  2.6.8 to 2.6.15.4 with some steps bitween those versions, and the
problem is still here. I have tried some live-cds with same results as my
stable system.

Analog stereo output works with no problems. If someone did tell me what I
should test on my system so that I could give the results to you.

These aren't broken:
 * my external amplifier
 * the digital coaxial cable
 * speakers etc.

Please tell me at least what to do, what to search for, or something...

Sorry about that incomplete post, hopefully this tells something to you.

In alsa.txt is my alsactl output.
The programs I have used: aplay, xmms, xine, speaker-test

I have tested different mixer values, sometimes in order, sometimes
random. But now I tested with speaker-test. (I tested with two channels
only, because if two works, maybe the other 3 would work...)

* speaker-test -c 2 -Dhw:0,0,[12] -> only analog stereo
* speaker-test -c 2 -Dhw:0,0,3 -r 44100 -> no sound, but plays (44100 was
the first samplerate I tried after it said: "Setting of hwparams failed:
Invalid argument Rate 48000Hz not available for playback: Invalid
argument) 
* speaker-test -c 2 -Dhw:0,0,[4567] -> Playback open error: -16,Device or
resource busy
* speaker-test -c 2 -Dhw:0,1,0 -> only analog stereo
* speaker-test -c 2 -Dhw:0,1,[12] -> Playback open error: -16,Device or
resource busy

Don't ever use hw unless you know what you're doing.

Try
   % aplay -Dplug:spdif something.wav
