I have just bought a streambar and am trying to connect it to my Samsung UE32F5500 which supports HDMI ARC. Without an optical cable connected, I get no audio at all (from TV speakers or streambar) when the source is the TV built-in freeview tuner.
The CEC/ARC option is enabled on the Samsung, and TV audio set to 'receiver', but I get no audio at all when I switch to the built-in TV freeview.
The input is not labelled (I have it plugged into HDMI1) but CEC seems to be working, as I get ANynet+ disconnected message on the TV when change source from HDMI1, and Anynet+ vol messages when I increase/decrease volume with either roku or freeview as the source. Just don't get any audio with the freeview selected.
I don't see any option to refresh the CEC devices.
