Thanks for your reply.
Yes I am using plughw - "plughw:0,0" and OMAP3530 Torpedo board. And I am attaching my own sound card driver on McBSP 3.

Hi all ALSA experts,
I am seeing a weird behavior of ALSA API lib 1.0.23, i.e., when I use SND_PCM_FORMAT_S32_LE, I am seeing that the data format is still configured as SND_PCM_FORMAT_S16_LE and passed to kernel driver layer.
Perhaps your hardware doesn't support S32_LE, and your application uses 'plughw' ?
