I have this problem too - but probably others causing it.

aplay -D spdif /usr/share/sounds/startup3.wav works fine.

aplay -D /usr/share/sounds/startup3.wav gives the following error:

ALSA lib pcm.c:1975:(snd_pcm_open_noupdate) Unknown PCM
/usr/share/sounds/startup3.wav
aplay: main:508: audio open error: No such file or directory

cat /usr/share/sounds/startup3.wav > /dev/dsp
makes no sound and hangs for 55 seconds on this 2.5 second sample.

They both worked before I installed 1.0.7.  However, I also installed
the OSS compatibility libs this time.

Also when I run alsaconf now it finds 2 cards even though I only have 1.
emu10k1    Creative ...
legacy       Probe legacy ISA chips

I suspect this second device is the tiny speaker on my motherboard, no? 
Is it getting all the attention?

Except for when I specify spdif on the command line "alsaplayer -d spdif
..." none of my audio apps work.

What gives here?  Anybody know?  Everything USED to work.

my .asoundrc is as suggested for my card (Audigy2 Platinum):

pcm.emu10k1 {
   type hw
   card 0
}
                                                                                                                       
ctl.emu10k1 {
   type hw
   card 0
}

thanks guys,
brian
