When streaming movies/tv shows from the SmartHub on my Samsung TV I am unable to get the audio to flow to the Samsung Blu-Ray theater system. The sound will only play directly from the TV. We have a Comcast cable box in the set up. The connection from the Blu-Ray is plugged into the HDMI(ARC) on the TV. There is an optical audio cable from the cable box to the Blu-Ray. Any thoughts? It seems we should be able to stream sound through the Blu-Ray.
