It is an older receiver - Yamaha HTR-5540
it looks like that one came out about 6 years before HDMI took over the AV world. Another possibility is if the TV itself has analog audio outs, you could run those into the receiver? How is the box that works connected? Does its audio outs go straight to the receiver or to the TV?
Looks like the box audio goes straight to the receiver.
Attached is a picture of the TV options and of the back of the cable box.
Looks like the audio outs on TV could go to the cable box, but I don't want cables hanging out. I have a hole in the wall behind the tv- not sure I could snake an rca pin back there but I guess I can try (or at least first try the tv audio out to receiver to see if it works). What would the rca pins go into on the back of the receiver ... any unused female like CD or V-Aux ?
I would assume that the audio connections in your TV picture are inputs. I think "AV IN 2" labels all the jacks below it. But you may have audio OUTPUTS elsewhere.
I think I'm looking at the side of your TV - there may be more ports on the back, (Side ports are often meant for convenient temporary connections.)
Yeah any input on the receiver should work - then you just select whichever one it is.
Since audio is already connected from the tv to the receiver and works fine thru the receiver on regular tv, I am still not clear why it does not thru the receiver when I switch to Roku. Assume it is because Roku is going thru HDMI 3 - a different input. Attached is the diagram of the back of the TV. Does that show you how this might be corrected?
