Hi,
Thanks for your reply. In my code I check if I'm on big or little endian
machine in order to append _BE or _LE.
I have already tried with SND_PCM_FORMAT_FLOAT (CPU endian) and the problem
remains..

For some unknown reason, I seem to be unable to

This line used to work with alsa 0.9 but return an "Invalid argument"
error with alsa 1.0.14a :
snd_pcm_hw_params_set_format(alsa_pcm_handle, alsa_hwparams,
SND_PCM_FORMAT_FLOAT_LE)
You probably want SND_PCM_FORMAT_FLOAT (without the _LE at the end)
to specify CPU native float. Using SND_PCM_FORMAT_FLOAT_LE will mean
that your code is almost certain not correct for big endian CPUS.
Example code at lines 1031-1041 :

ate=1.19&root=freecycle
That should probably be fixed as well.
