A couple of years ago (so may be inaccurate now) I concluded after some 
testing that S24_LE was broken in arecord and aplay, at least when it came 
to .wav files. Meaning that files I recorded with arecord could be played 
back by aplay, but not in any other application I tried, such as Audacity.

I can try to dig out the gory details, but ISTR it came down to the 
header(s) in the .wav file being incorrectly filled in with regard to 
number of bits per sample vs valid bits per sample.
