There is a fault with the file, as reported in the screenshot, in that
the iXML chunk after the data chunk is shown as starting at an
odd-valued address, whereas all chunks should start at a word-aligned
address (an odd-sized chunk, as may easily arise with 24bit audio data,
should be followed by a pad byte). Whether that is what is foxing
QT7.6.6 I can't say - might not matter if it simply doesn't bother to
read non-essential chunks after the data chunk.
One very clever thing about the "sndfile-info" utility is that it does
not only report chunk details, it reports any chunk arithmetic or size
errors as well. I would like to have a short example soundfile with the
same features (i.e. the audio content itself is immaterial, a sinewave
would do), to post on a web page I am planning illustrating such
odd/wrong aspects of file formats, especially as created by leading
industry-standard software. You could be forgiven for thinking those
software houses aim to employ best practice in writing soundfiles, but
unfortunately the evidence is that they happily play somewhat fast and
loose with "so-called standards".

Hello to all, thanks for the replies.

Given that QT X has a rebuilt underlying engine, I think it makes sense
that the modification
in the header simply confuses the older QT 7 and I don't see this
fixable. Of course, I 'd love to be proven wrong, hence my posting
to this mailing list. I found a very handy utility online, bwavreader,
that gave me even more information, those who want can check it out
here, it is a simple png screenshot:
