/** @file paqa_devs.c
@ingroup qa_src
@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.
