Hi all - 

First post. I got my X51 yesterday and so far am very happy with it. I have connected my X51 via HDMI to my Samsung TV and get audio/video. However, I want to output the sound from it via my optical cable via the optical out port. The port emits the usual red light, and the cable has been confirmed as working. However, I get no audio.

What settings do I need to tinker with (guessing sound in control panel)  to get the sound I am after?
