Command line options support - opening every device, or all input devices, or all output devices. - 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 sine wave outputs. - - @author Phil Burk http://www.softsynth.com - - Pieter adapted to V19 API. Test now relies heavily on - Pa_IsFormatSupported().
