Comment (by heleppkes):
WAVEFORMATEX is a Microsoft format, and they clearly define that bits per
sample is only allowed to be 8 or 16 with WAVE_FORMAT_PCM, and only with
WAVE_FORMAT_EXTENSIBLE higher bit depths are allowed. See

FFmpeg should not be creating out of spec files, even if some occasionally
software can read it.
