When the header file was created many years ago, 24000 Hz wasn't a common sample rate. To support a sample rate that is not in that list of predefined rates, your driver should set the RATE_KNOT bit and call the snd_pcm_hw_constraint_list() function; see the section "Constraints" in the "Writing an ALSA Driver" document.
