| @brief Self Testing Quality Assurance app for PortAudio |
| Try to open each device and run through all the |
| possible configurations. |

| @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. |
