I thought optical out was 2 channels only? Don't you need to connect to your amp via HDMI? I could be wrong, mind, but I just seem to vaguely remember reading this recently.
EDIT: No, that's not right. It was something to do with HD audio, whatever that is.
Most TVs won't output surround sound via optical and just dumb it down to stereo. Sony TVs are generally pretty good for this though and I know mine will do it because I've tested it with the PS4 and it works fine. What optical won't handle, as you say, is the higher definition surround sound that you get on Blurays but I'm not bothered about that.

Anyway, try and google "optical vs hdmi", there seems to be a lot of discussion about this that might give a clue.
I'm not sure that's relevant; my issue is that my PC doesn't seem to want to output surround via HDMI as opposed to anything to do with optical. Given that the PS4 manages surround perfectly well going HDMI->optical I'm assuming the problem here is the PCs HDMI connection to the TV as some level.
