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() -returns 24 in the case. +returns 24 in this case. \section alsa_transfers ALSA transfers -- 1.7.9.2
