Hey all, first time post, long time admirer of the forum, and mods I did a search on this topic and didn't find a post that answered this Q, but feel redirect the post. I want to start mixing some projects to 5.1, so my first question is actually hardware regarding outputs from a Mac Book Pro. Someone said in another forum that every Mac Book Pro has optical out, so I'm assuming that statement means that it "has the capability of optical out" via a Mini plug to Toslink adapter, correct? So if the MBP can send out a digital signal via the mini plug to Toslink, do you now have the ability to monitor and mix your project in 5.1 discrete channels with a MBP? Obviously assuming you have 5 speakers and a sub and the Receiver to decode the optical cable. I have more questions but I'll just leave it with this. Any factual comments?
