Will my old Sony DVD receiver work with a Sony 4K Blu Ray player?

An output cannot act as an input. An input cannot act as an output. There are a (very!) FEW pieces of equipment --- but Not Any disc players --- in which a single connection can be switched from being an input to being an output. This is an Extremely Rare feature in consumer products, so don't look for it.

Don t buy things that are incompatible with your other equipment, unless you are ready to upgrade your other equipment. There are players that have analog (RCA) audio outputs on them, so forth. Why purposely buy an incompatible player? Save a nickle on the player so as to make certain you need to spend 500 bucks on a new receiver is not common logic. Yes, the industry WANTS you to run right out and buy lots of their stuff. But there is always compromise gear made available in any changeover market, if you look for it. And yes output is output, input is input.

The outputs on the back of the unit are a HDMI Audio/Video output and a HDM Audio only output. The problem is that your Reciever only has a HDMI Audio/Video output. So that's three outputs and no inputs, and from what I can find there is on "ARC" (Audio Return Channel) on the HDMI of the receiver Depending on what you are trying to do though, you should be able to connect up the audio from the TV or the BlueRay via the SP/DIF connection. *Instructions are in the user manual!
