It turns out it was an error on my part; sorry for the trouble. I misunderstood
the format libflac was expecting my samples in. I found the wording in the
documentation very confusing.
My audio file has 2 channels and 16-bit samples, so I have to pull out each
individual sample, push it into a FLAC__int32, and fix endian-ness before I can
pass it to libflac.
The documentation made me think that libflac just wanted me to shove my 2-byte
sample into a FLAC__int32. I wasn't aware that it wanted me to extend the sign,
