Your questions are difficult to understand...

Lets start with the simple things:
Please remove everything starting with "-f" until "s16":
If "ffmpeg -i 684.wav" does not work as expected, please 
report back / try to set some values that you seem to believe 
are necessary (but shouldn't be).
Once that works, try to understand what "-f" does and why you 
should only use it for raw pcm files (in this case).

(I wonder what -sample_fmt means: I test often and I believe 
I never used it...)
