    • Windows 8 (64bits) / mingw / Qt 5.2.1 for Android (Windows 32-bit, 1.1 GB)

      Mono sounds most of the time don't work on windows 8 but the same one encoded in stereo (sox mono_ko.wav -c 2 stereo.wav) works fine.
      The attached qt creator project has 3 rectangles where when clicked on, the mono_ko, mono_ok and stereo are played. The stereo and mono_ok are played while the mono_ko isn't.

      mono_ko.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 44100 Hz
      mono_ok.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 8000 Hz
      stereo.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo 44100 Hz

      I tried changing the rate of the mono_ko to 8000Hz too, but didn't work either.

      Feel free to ask me to do any test if that can help.
