+    @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.
