Macbook pro retina with z506 5.1 ch speakers
I have seen some articles saying Macbook Retina has 'Optical audio output'.
What does that mean?
Does that mean I can plug z506 speaker into the Retina macbook through 3.5mm jack and it 'simulates' 5.1 ch sound ?
or it is going to be like 'stereo' sound?
I understand 5.1 ch speakers need to be plugged in with 3 cables.
But wanting to find a 'easy and cheap' way even if it will not be true 5.1 ch or whatever.
MacBook Pro (Retina, Mid 2012), OS X Mountain Lion (10.8.2)
