Comment (by richardpl):

 You are not testing demuxing at all, you are testing decoding. As I
 already said demuxing is perfect, the only thing that is missing is number
 of samples in last packet - which is essential for correct decoding of
 last frame, but for some reason you cut out error reported in decoding.

 How foobar manages to guess number of samples in last packet is essential
 to solving this bug.

 AFAIK there is nowhere in matroska stored actual number of audio samples
 put into TTA stream.
