My name is Khan.
Ticket is not ffprobe related.

Do you have more unrelated questions?

Sorry for not adding a workaround originally.
This is not the correct workaround (suggested ​elsewhere):
ffmpeg -f s16le ...

The following works as expected:
$ ffmpeg -acodec pcm_s16le -i steps-stereo-16b-44khz.wav
