Hmm, from 2.0.1's man page (doc entry for -f):
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".
:) 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.
