Following up, the kernel was compiled using gcc 3.4 instead of gcc 4.1 and the alsa driver seems to work better. This is a toolchain problem, according to Atmel and our distribution vendor.
But, we get the following error messages:
-bash-3.1# aplay -D default Noise.wav
Playing WAVE 'Noise.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
ALSA lib pcm_plug.c:773:(snd_pcm_plug_hw_refine_schange) Unable to find an usable access for 'default'
aplay: set_params:909: Channels count non available
Could it be possible that there is something fishy going on with the alsa-lib ?
Appreciate your input..
Thanks,

Hi Takashi,
Omitting the --prefix =/board-rfs, DESTDIR=/board-rfs was passed in make install, and on checking, it seemed that the bin, lib, share and include components of the alsa-lib were installed under /board-rfs/usr
However on running an application, this is got
-bash-3.1# ./soundtest default
ALSA lib pcm_params.c:2152:(snd_pcm_hw_refine_slave) Slave PCM not usable
cannot initialize hardware parameter structure (Invalid argument)
Setting the environment variable $LIBASOUND_DEBUG to 1 does not cause any debugging information to be displayed to stderr. (I double checked via #echo to make sure LIBASOUND_DEBUG was set to 1)
I'm clueless, am I doing anything wrong ?
Thanks much,
iyer

But --prefix=XXX overrides the path embedded in the code. For
installing to another root, passing DESTDIR=XXX at make install is the
standard procedure.

This is a different thing. Now the system files are properly set and
alsa-lib reads them. But, the driver returns an error for the
required PCM setting.
Try to set $LIBASOUND_DEBUG to 1. Then each hw_params error will be
displayed to stderr. See alsa-lib/NOTES for details.
