I have just bought LG 47LW5700 TV and a Sony BDV-E980 home cinema. Got them both setup and working fine except I can't connect the two through the ARC cable so that the tv sound comes through the home cinema. I have put the ARC HDMI to HDMI 1 on both systems, turned sound on the TV to Auto instead of PCM. That's as far as I have got Any help would be appreciated please
if the tv has an ouput for spdif or digital coax and your home theatre has an input of spdif or digital just connect up a cable and adjust the input on home theatre to tv to have the sound,try that.
