/** @file paqa_devs.c
@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.
