as far as I know: sample format S24_LE is 24bit sample in 4 bytes sample format S24_3LE is 24bit sample in 3 bytes (why else have separate definitions), right ?

Yes.

In the ALSA-LIb example /test/pcm.c however (http://www.alsa-project.org/alsa-doc/alsa-lib/_2test_2pcm_8c-example.html) there is no diff between the 2 sample formats.

That example program uses snd_pcm_format_width() although it should have used snd_pcm_format_physical_width() when calculating memory buffer sizes.
