We know that High Def sound may or may not pass. Be sure that all audio is set to stereo to avoid HDCP stopping the audio.
When I connect media players to HDMI inlets (1 to 4) of the TV, the image is perfect but there's no sound.
These same media players (and cables) connected to an old TV sound perfectly.
Adding mistery: when I connect the samsung BD-player to the HDMI inlets of UE40F7000SL, sound exists!
Has anybody experienced this?
