As Thom guessed, he broke the WAV codec while code-policing it...
So, Thom, I'm donating that DVI ADPCM file from my own private
collection so that you can fix your bug :-)
get it at http://devernay.free.fr/hacks/dviadpcm.wav (it's recorded from
an Olympus voice recorder). You can attach it to the codecs page in the
wiki if you want (it's 15Kb).
I'm attaching a patch the DEBUGFs I use for the WAV codec, you'll see
that chunksize==0 so that the file doesn't play. The previous version
worked.
