So, a very novice user here please bare with me. I'm (trying to) using my Samsung RX-V373 AV receiver strictly as an HDMI hub for the time being. I'm running 4 different components into the HDMI inputs and one HDMI cable running out of the receiver directly to the HDMI2 input on my TV. Video is coming in fine from all 4 inputs. However...no audio. Is the audio not running through the HDMI cable between the receiver and the TV for some reason? Is there a basic setting option I'm missing?
