I don't know the exact problem but from your output I'll take a guess of 
the general area.

Right after the "fmt" chunk should be the "fact" chunk.  Instead of 
finding that, it found "FF?".  I looked at monkey.wav and the only 
occurance of "FF" is at the very beginning of the file where it has "AIFF".

So it seems maybe the file somehow did a rewind.  SoX does use fseek() 
to jump to the next chunk faster and in fact new to 14.0.0 is changing 
to fseeko() to seek into larger files.

So I'm guessing something about Slackware doesn't like fseeko().  
Hopefully, this gives some hints for others to help pinpoint the problem 
faster.
