Hello, I have a Samsung UN55MU6500F smart tv and am connecting it to a Yamaha YAS-108 soundbar. The ARC feature is not working properly. I connect the HDMI cable to HDMI3 on the TV and to the HDMI out on the Yamaha YAS-108. Anynet+ is also enanled on the TV. The TV will turn on the YAS, and also turn it off. However, I cannot hear any sound at all. Any suggestions?
