That file is bigger than 4 Gig and WAV files are limited to 4G due
to the use of an unsigned 32 bit integer in the WAV file header.

More likely to be due to the file size.

Try using sndfile-convert (in the sndfile-programs package in
Debian/Ubuntu) to conver the file to a format which allows
files larger than 4G. Try:

    sndfile-convert large-file.wav large-file.w64

Let me know if that doesn't work.
