ALSA 0.9.0 doesn't define either. It does define

       SND_PCM_FORMAT_S32_LE
       SND_PCM_FORMAT_S32_BE
     
but note that very few audio interfaces support literal 32 bit sample
values. Most do 24-bits-packed-into-32. The only exception I know of
is the Creamware Pulsar/SCOPE systems. 32 bit A/D converters are not
commodity items yet, even in high-end audio circles.
