Okay so I have the YHT-S400 and I am wondering how to hook it up using HDMI, this sound bar and others I have used in the past I can get to work pretty easily by using the optical out on the tv to the optical in on the receiver and then everything I have plugged into my TV I am able to get to play though the soundbar. My question is can I do this using an HDMI cable? On the receivers instructions it says to plug into the HDMI out on the receiver and then to (any?) HDMI in on the TV but I cant get any sound to work. So is this possible? Can I get it to work like the optical where everything I have plugged into my tv will play through the soundbar?
