I think this is a jackd issue. I found the following from

Use of 'f32_le' (32bit floating-point) is correct, as it is the
audio format used in communication between JACK clients and the jackd
server. Jackd, which does the actual soundcard i/o, will first try to open
devices in mode s32_le, and only if that fails, revert to s16_le. Other
sample formats are not supported at the moment. But anyways, I don't this
is causing the problems.
