First of all, my mistake. The AudioFormat it was being set to was -2
(0xFFFE). But after running sndfile-info as you suggested, it did
indicate WAVE_FORMAT_EXTENSIBLE.

Thanks for this. It worked. (As a side note, it also seemed to work
where I used a hex editor to change the value 0xFFFE -> 0x0001 in file)
