Could someone please advise me on the hospitality mode for Lifestyle 650. I would like to know if the system would switch on/off following the TV if there is nothing connected to it but an analog or optical cable from the TV. As in, would it auto wake up when the TV audio comes on? My requirement is that the Lifestyle should follow the TV audio, as there are no other inputs connected to the Lifestyle other than the TV. Basicly, it should just follow the TV audio and switch on/off following the TV.
