Totallymaxed - sorry, yeah saw that after I posted, haven't read it closely, but there was a diagram of a panel of outputs that didn't include the SP opt, but further down it talks about them (and even SP in [optional]) ... not sure why. But glad to hear that it has it anyway!
On the HDMI - I know that the video works fine, but I have read on the forums that the audio through HDMI doesn't - and that post also mentioned Realtek and that the Linux driver probably needs this implemented. Are you saying that you can get digital audio out of the HDMI interface out of the box with LMCE? Pushing my luck here.... but .... what about the CEC control interface?
