2) The wav sink doesn't seem to close the wav-file correctly. After
writing an 82MB file, the size of the file (bytes 4-7) were 0. Many
programs don't seem to mind this. 'snd' doesn't like it and won't open
the file.

Also, the size of the 'data' block in the wav-file is not set.

Though I have seen the 'closing' routine in the wav code, can it be
that it isn't called?
