[alsa-devel] Why is SND_PCM_FORMAT_S32_LE not able to be set and passed to Linux Kernel Asoc?

[Philip Chu]

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.

Perhaps your hardware doesn't support S32_LE, and your application
uses 'plughw' ?
