In the spirit of moving ahead I have been investigating the use of
libsndfile as a library for sound files.  I have the output section
working and the code is a little simpler.  I am still not convinced
it is the "right" library, but it certainly does remove a lot of
suspect code.  Some issues still need to be resolved.
  I have added a flag _SNDFILE_ to use this instead.  If this seems OK
I will remove all this and simplify the code.  Needs some changes to
the configure stuff as well if accepted.
