We have a new Sony XBR TV and a new Bose Lifestyle 535. Speakers set up, check...We don't have cable or a DVD play, just WIFI streaming Netflix throught the TV. The TV is not playing through the Bose speakers. Do I need another cable? There is an HDMI cable that goes from the back of the Bose to the HDMI 1 on the TV. When I choose HDMI 1 on the TV input on the Bose remote, it still doesn't come through the speakers. Help, please.
