Ok, should suffice. [In my case snddevices made many other device
files.]

Well, I think the way you specify the device is wrong. AFAIK the -D
option only accepts names which are defined in an ALSA configuration
file (.asoundrc & friends).
Furthermore: Did you try without any device (without -D option)? The
defaults should make ALSA pick the first available sound device. At
least, while I was testing, I didn't have to specify any device.
=20
BTW: You need to specify the (.wav) file you want to play:
# aplay music.wav
Otherwise you won't here anything ;-). Read "man aplay" !

cannot open audio device /dev/snd/pcmC0D0p (No such file or directory)

=20
Ditto. But I haven't had a look into test_sound source yet, but it might
be the same issue.
