Those are now all part of the "raw-format" property - so you only have
to set one property instead of half a dozen:

  raw-format          : Format of audio samples in raw stream
                        flags: readable, writable
                        Enum "GstAudioFormat" Default: 4, "s16"

LE = little endian
BE = big endian

U = unsigned
S = signed
F = float/double
