I recently purchased a Vizio E Series Razor LED 60" tv for my home, and connected my Vizio Sound Bar with Wireless Subwoofer 2.1 and it isn't working. The TV plays sound with built in speakers fine, but the sound bar gets nothing, even if I turn off the TV speakers. I made sure the volume was up and connected it right, although there didn't seem to be an optical audio connector on the back of the TV. Thanks in advance.
