12. Multiple sound-devices and multi-channel sound?
Look at the Audio->Device menuitem. You can set this option permanently by going into the Preferences and choosing Modules -> audio output -> coreaudio -> audio device (You will need to choose "Show Advanced options" first).
- You should change your speakerlayout in the Audio Midi Setup utility. The program is located in /Applications/Utilities.
Select your audio device in "Properties For:", then click the "Configure Speakers" button. Choose "Multichannel". Even if these settings are correct, you should change them and click "Apply", then change them back and again click "Apply". This is important, otherwise VLC cannot reliably detect which speakers are connected.
- We are in a transitional phase for our Mac OS X audio system. Therefore it is currently not possible to use Digital audio without changing a Preferences setting. The setting is in Audio->Output modules. Change this from default to "CoreAudio output". This is the module that was also used in previous versions of VLC. It has several issues with Analog audio, but it also supports Digital audio, which the new module does not yet support. You should ONLY use this module for Digital output.
