Andrew,
cygwin setup is not aware of any snapshot you can install manually,
as it compares the info from setup.ini (from website) with
the info stored on its database /etc/setup/installed.db
So if you have
$ cygcheck -c cygwin
Cygwin Package Information
Package Version Status
cygwin 1.7.9-1 OK
as 1.7.9-1 is the last released version, running setup again
to upgrade octave, will not replace your snapshot.
I am also running a snapshot as 1.7.9
$ uname -rv
1.7.10s(0.255/5/3) 20111129 17:41:48
for the reason reported on
http://cygwin.com/ml/cygwin-announce/2011-10/msg00001.html

It seems a different problem of the bug you thought about,
both the 3.4.2-3 and the latest development build do not recognize
the file format.
octave:2> Y = wavread("428shortMono.wav")
error: wavread: file contains no RIFF chunk
error: called from:
error: /usr/share/octave/3.4.2/m/audio/wavread.m at line 74, column 5
octave:2> exit
octave:2> Y = wavread("428shortMono.wav")
error: wavread: file contains no RIFF chunk
error: called from:
error: /pub/hg/octave_build/../octave/scripts/audio/wavread.m at line
77, column 7
Please note that
$ file *.wav
428shortMono.wav: RIFF (big-endian) data, WAVE audio, mono 44100 Hz
oddchunk.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM,
16 bit, mono 1000 Hz
I am not sure that your file is compatible with octave expectation,
I suggest to rise the question on octave-help as I know nothing about
sound file format.
Regards
Marco
