The 24-bit linear samples use 32-bit physical space, but the sample is
stored in the lower three bytes. Some hardware does not support processing of full
range, thus you may get the significant bits for linear samples via
#snd_pcm_hw_params_get_sbits() function. The example: ICE1712
chips support 32-bit sample processing, but low byte is ignored (playback)
or zero (capture). The function snd_pcm_hw_params_get_sbits()
