Thank you. I do have it connected with the HDMI only at this point. The problem if I use the optical cable and turn off the HDMI control is that the sound from the cable box never goes off, even if (1) I am trying to watch programming from one of the apps or (2) when I turn off the TV and the receiver remains on. Also, even though I chose the opt 1 input on the receiver, I don't think the optical cable is transmitting the sound. When I disconnect it while the TV is on, the sound continues. Is there something else I need to do? (I have the input for cbl/sat set to both HDMI1 and opt 1.
