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 H= z, Mono
ALSA lib pcm_plug.c:773:(snd_pcm_plug_hw_refine_schange) Unab= le to find an usable access for 'default'
aplay: set_params:909: Chan= nels count non available

Could it be possible that there is some= thing fishy going on with the alsa-lib ?

Appreciate your input..=

Thanks,
iyer

Hi Takashi,

Omitting the --prefi= x =3D/board-rfs, DESTDIR=3D/board-rfs was passed in make install, and on checking, it seemed that the bin, lib, sh= are and include components of the alsa-lib were installed under /board-rf= s/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 parame= ter structure (Invalid argument)

Setting the environment variabl= e $LIBASOUND_DEBUG to 1 does not cause any debugging information to be di= splayed to stderr. (I double checked via #echo to make sure LIBASOUND_DEB= UG was set to 1)

I'm clueless, am I doing anything wrong ?

But --p= refix=3DXXX overrides the path embedded in the code. For

Th= is is a different thing. Now the system files are properly set and
al= sa-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 t= o stderr. See alsa-lib/NOTES for details.
