Log:

Fix 7.1 channel order in CoreAudio (mac).

To activate 7.1 audio (using either HDMI or DisplayPort); make sure to first launch the Audio MIDI Setup in /Application/Utilities and configure HDMI audio as 8 channels-24 bits (the default is just stereo). It is recommended to disable DTS and AC3 passthrough as it would reset the hdmi audio in two channels mode, which would break future multi-channels playback.
Note that for the time being, E-AC3, TrueHD and DTS-HD MA bitstreaming do NOT work under MacOS. That's until Apple provide the required 192kHz digital sampling rate (the hardware supports it!).
