You suggested in another thread that I use csnd.CppSound() instead of
csnd.csoundCreate(args*), and I don't have any examples using
csnd.CppSound() with .SetPythonMessageCallback(func) or
.SetMessageCallback(func).
What I need is to find what audio devices are available for any given
module.  It seems a callback that logs Csound's output is the simplest
way to do that.  None of the examples I can find do this.
