I see it, but not if I encode myself with 1.1.6. You probably used
another version for encoding.

The problem (which might not even be there anymore) would not be in
Speex (libspeex) itself, but merely in the command line tool(s). It be a
shame if these caused you to buy an expensive codec instead ;-)

You sure you *encoded* the file with 1.1.6. Also, there's a known
(minor) issue with gapless for very short files that only contain one
Ogg page.

I get the tick when decoding bad.spx, but encoding+decoding bad.wav
works fine for both 1.1.6 and 1.1.10.
