Well, I realize that the drivers and modules for sound are already on the gumstix. I wonder if it is just a matter of getting the utilities on the gumstix to use it?

Has anyone had success using native ALSA?  i.e. not using OSS emulation?

I'm using the latest SVN build 1005 and can't get any apps to open the
ALSA device.

Using http://alsa.opensrc.org/faq/#FAQ007 as an 'Is ALSA working?'
reference, I find that the modules are correctly loaded and /dev/snd and
/proc/asound all appear to list and say the right things.

amixer outputs:
ALSA lib control.c:817:(snd_ctl_open_noupdate) Invalid CTL default
amixer: Mixer attach default error: No such file or directory

aplay outputs:
ALSA lib pcm.c:2099:(snd_pcm_open_noupdate) Unknown PCM default
aplay: main:547: audio open error: No such file or directory

I'm wondering if the PXA2XX drivers do things a little differently.
There is no /dev/snd/hw* like my PC.

Both the kernel and userland libs are the same version ( 1.0.11rc2).

I also figured I should be able to do something like this (as I'm
assuming pcmC0d0c is a character device):
# cat /dev/urandom > /dev/snd/pcmC0D0c
It returns:
cat: Write Error: Invalid argument

Am I missing something?  Anyone have any ideas?
