Applications using QAudioDeviceInfo which work fine with Qt 4.8 to Qt 5.1.1 now find audio devices only when run from QCreator. After running ~/Qt5.2.0/5.2.0-beta1/clang_64/bin/macdeployqt on them no audio device is found anymore.

This includes the Qt 5.2->Qt Multimedia-> Audio Devices Example.

Load it in QCreator and run: all audio devices are found.
Run macdeployqt on the app, and then run the app directly (not from QCreator): no audio devices found.

That means no audio for any Qt 5.2 Multimedia app to be deployed on Mac.

No code attached, as you can reproduce using the Qt Multimedia Audio Devices Example.
