    @brief Self Testing Quality Assurance app for PortAudio

         Try to open each device and run through all the

         possible configurations. This test does not verify

    that the configuration works well. It just verifies

    that it does not crash. It requires a human to listen to

    the outputs.

        @author Phil Burk  http://www.softsynth.com

    Pieter adapted to V19 API. Test now relies heavily on 

    Pa_IsFormatSupported(). Uses same 'standard' sample rates

    as in test pa_devs.c.
