Some windows and osx users can't open their aif files. Other formats seems to work and even other aif files. I could not reproduce the issue on my windows and osx system. The files load without any issues. Following line seems to return nullptr and the file can not be loaded:
ScopedPointer<AudioFormatReader> audioFormatReader(audioFormat->createReaderFor(inputStream, true));
The file permissions seems to be ok. Does anyone have an idea what the problem can be?
