I'm connecting the digital audio out directly from the Genie to the digital audio input (coax) on the Vizio Soundbar. The HDMI cable is going to the monitor (which has no sound/speaker cabability--it's just a monitor).
The cable is Mediabridge http://www.amazon.com/gp/product/B00FMZX4DS/ref=oh_details_o03_s00_i00?ie=UTF8&psc=1
and the Vizio Soundbar is Amazon.com: VIZIO S2920w-C0 29-inch 2.0 High Definition Sound Bar with Bluetooth: Electronics
