Connecting to my 1 Year old Samsung 49" Curved Smart TV.
Connected from HDMI out on Soundbar to HDMI Arc on TV.
Volume changes on sound bar (from lcd indicator) but no sound comes out of either my PS4 or the Sky Box.
In the settings for the TV it shows Speaker is Receiver HDMI other options are TV Speaker and Audio Out.
I can play music via bluetooth. I don't have a optical cable to test.
ARC appears to be working, no sound though!
Did a reset of the sound bar, when it powered up sound was coming from the TV. Hit input on the sound bar to TV (options are USB, BT, TV, Optical). and sound went away!
Not sure what else I can do.
