It's supported.

Hmm, from 2.0.1's man page (doc entry for -f):
--cut--
              fied, host byte-order is used. Currently supported
              formats are "u8" (same as "8"), "s16_le" (same as
              "16"), "s16_be", "s24_le", "s24_be", "s32_le",
              "s32_be", "f32_le" and "f32_be".
--cut--

:) But of course, as I can't fully test these pro audio related features,
there might bugs. You should also try "s24_le". This is also a 32bit
data format, but the lower 8bits are always null. This is used at least in
a few higher end cards.

But I'd be interested in strace and gdb traces.
