Hi Sonos, I just received my Playbar. I have a Sony Bravia 46" (KDL-46XBR2). It receives audio via an HDMI connection from the cable box. It is directly connected to the Playbar via the included optical digital audio cable. As I set up my Playbar, I am getting the message, "Sonos could not detect any audio from the TV." I have tried another optical cable. My TV doesn't necessarily have a "digital audio out" setting in the menu. It only has the option to turn the TV's speaker ON/OFF, though when I had the TV audio output going through component cables to a Play:5, it worked fine. Any troubleshooting steps?
