I would think that this sounds like a version mismatch. How do i come to
this result? Well, alsamodules seem to be laoded fine [as you have
checked /proc/asound/cards]. Oss emu is working too [as you /dev/dsp
test shows]. The OSS emu [modules] don't interact with alsa-lib. But the
pcm-test program uses alsa-lib..

which version of alsa-drivers do you use [cat /proc/asound/version]?
which verison of alsa-utils do  you use [aplay --version]
which version of alsa-lib do you use? [$EDITOR
/usr/include/alsa/version.h]?

Flo

P.S.: oh i just see you use ARM. I have no idea, if that platform has
specific issues, so this post could be void afterall..
