qtmultimedia/tests/auto/integration/qaudioinput/tst_qaudioinput.cpp
Kurt Korbatits 301ed096f8 Updated QAudioOutput and QAudioInput system tests 
- Updated tests with volume checking.
- Updated reset function in QAudioInput test.
  (Checking bytesReady() in pull mode is not valid)
  (Checking state after writing one byte doesn't guarantee going to active state)
- Improved stability in CI system
