Hi all,

I don't get any sound from the S/PDIF output of my M-Audio Audiophile
24/96 when using ALSA native mode. This is what I tried:

  madplay -o raw:- test.mp3 | aplay -c 2 -f S16_LE -r 44100 -D plughw:1

This gives only sound output on the analog output (the Audiophile is
the second sound card, the first card is a SB AWE64 Gold which I use
for desktop audio). If I try to select a second output, it simply
doesn't work:

  madplay -o raw:- test.mp3 | aplay -c 2 -f S16_LE -r 44100 -D plughw:1,1
  ALSA lib pcm_hw.c:597:(snd_pcm_hw_open) open /dev/snd/pcmC1D1p failed: No such file 
or directory
  aplay: main:446: audio open error: No such file or directory

However, S/PDIF output works perfectly with OSS emulation:

  madplay -o /dev/dsp1 test.mp3

The manual shows that the Windows drivers make a difference between the
analog and S/PDIF output, so I expect that ALSA can do the same. Could
somebody shed a light on this before I dig up a datasheet and hack the
driver myself?
