The 32-bit default is floating point, and is roughly equivalent to 24-
bit fixed point, but float is more forgiving of gain staging and
doesn't have a hard limit.
There is no 16-bit floating-point format, so you would have to use 16-
bit fixed-point. There would indeed be less audio fidelity at 16
bits, but only if the hardware is 24-bit. If you have 16-bit hardware
then there would be little difference.
By the way, it's best to just stick with the 32-bit float default, and
let the hardware driver handle the conversion to whatever is best for
that particular hardware. 32-bit float is sufficient for all levels
of audio quality without sacrifice.

The hardware default for LPCM seems to be 32 bits per channel and thus

What happens if the audio format is set to 16 bits per channel? Less
audio fidelity?
