Always check the obvious stuff first does the card support S16_LE 32Khz data?
And if it's configurable for multiple formats, was it set for the correct one?
Does wireshark or other USB snoop program show any traffic at all?
Does the record die immediately, or hang for a few seconds and timeout?
Does 'arecord -v' or arecord -vv' tell us anything more about the situation?
