*** Unknown chunk marker (19A75F8) at position 393212. Exiting parser.
*** Chunk size 4292673536 > file length 27293176. Exiting parser.

Error in WAV file. No 'data' chunk marker.

PS. the output *** ��N comes from the "%M" in src/wavlike.c:1035, an unhandled default chunk.

PPS. The file plays fine with mplayer, ffmpeg and also older tools using libsndfile1.0.27
