No.  That's my point.  Something is overriding the usual mime types
mechanism.  If I use Konqueror to determine the mime type -- just by
the mous -position flash-up text says "Supported by Netscape plugin".

Nothing I can do with the usual mime types mechanism ever changes this
behaviour.

I thing au is a Sun format, though it may predate Sun's use of it. 
There are several possibilities.  The 16-bit linear PCM version used
for CD audio is big-endian.

No, it's not a substitute.  I have to work with both au and wav
formats.  The wonderful "sox" program converts between them.  Joerg
Schilly's cdrtools work with both and so should kreatecd.

I suspect new audio formats will continue appearing.  To get maximum
flexibility from kreatecd one ought to be able to configure a wide
variety of audio formats and specify a converter program to turn the
input file into one of cdrecord's natively supported formats..  The
default for this program would be "sox" in which case you would
immediately support several dozen other audio formats.  It also allows
resampling to handle formats other than 16-bit 44.1 kHz.
