First-time XBOX owner here - have just ordered a new one (Kinect Bundle). I believe this means it will have an HDMI output. I'll be plugging it into a projector at the back of the room, which has component, S-Video and HDMI inputs. The audio will be via a Squeezebox at the front of the room to start with (3.5mm jack input), but eventually via an A/V amp. I'm not familiar with how the XBOX outputs work. Bearing in mind that the video and audio are in opposite directions, which additional cables should I buy? If I simply buy an HDMI cable, will I already have what I need for the audio in the XBOX package? Thanks.
