Does Mac OS X support running digital signals to multichannel audio systems beyond 2.1 sound systems via optical audio outputs. Eg 5.1 surround sound, 7.1, etc speaker systems?
I have found a guide from 2008 for setting up some stuff, but it looks like it requires set up first in Audio MIDI setup???. Configuring 5.1 Surround Output in Mac OS X. Is this how it is still done on Lion?
