Answering my own question:

I was wrong to think this line:
    so1 = Import [ "Audio Track.aiff" ] ;
worked; it should have been:
    so2 = Import [ "Audio Track.aiff", "AIFF" ] ;
or:
    so3 = Import [ "Audio Track.AIFF" ] ;

so2 and so3 are correct; so1 is totally weird.

I was misled by the documentation for 'Import', which says:
"The format of a file is by default deduced from the file extension in
its name".

Perhaps this is a bug?
I note that both Wikipedia and Mathematica's own documentation
explicitly mention .aif, .aiff and .aifc (all lower cased) as the
extensions denoting AIFF files.
