I recently purchased one of these receivers and have the following problem.
Despite setting all the menus as the instructions say I do not receive any audio over the Audio Return Channel. The receiver recognizes that it is receiving the ARC signal, the TV recognizes that the receiver has been turned on and disconnects the internal TV speakers, however i still get no audio.
I have read that any HDMI cable is capable of supporting ARC and i don't want to waste money upgrading cable if this isn't necessary.
Does anyone have any ideas?
