Alsa and Audigy2 getting data but no sound through S/PDIF

I'm ignorant about sound cards. I've been through the wiki multiple times, the alsa-project site and another site.

Currently I have set my .asoundrc to

defaults.pcm.!card "Audigy2"
defaults.ctl.!card "Audigy2"

I have had the same lack of success with

pcm.!default {
  type hw
  card Audigy2
}

ctl.!default {
  type hw
  card Audigy2
}

The appropriate channels are unmuted and volume is up.

The config appears to work when using alsactl to monitor the default ctl device. I see the channels getting data, however, I don't hear the sound whether from youtube or speaker-test.

For example, running speaker-test I get

$ alsactl monitor default
#66 (3,0,0,EMU10K1 PCM Send Routing,0) VALUE INFO
#98 (3,0,0,EMU10K1 PCM Send Volume,0) VALUE INFO
#130 (3,0,0,EMU10K1 PCM Volume,0) VALUE INFO
#66 (3,0,0,EMU10K1 PCM Send Routing,0) VALUE INFO
#98 (3,0,0,EMU10K1 PCM Send Volume,0) VALUE INFO
#130 (3,0,0,EMU10K1 PCM Volume,0) VALUE INFO

When I set the S/PDIF channels I get

$ alsactl monitor default
#14 (2,0,0,IEC958 Optical Playback Volume,0) VALUE
#14 (2,0,0,IEC958 Optical Playback Volume,0) VALUE
#31 (2,0,0,IEC958 Optical Raw Playback Switch,0) VALUE

At this point I don't know what I don't know. The speaker setup does work on Windows.

Thanks in advance.
