Your receiver appears to have a digital optical input, so no converter would be needed, just an optical fiber cable (TOSLINK) between the two optical ports. However, the manual for your receiver states that several functions don't work unless there is also an analog connection. If you must have those, you can use an HDMI audio extractor. You may also need an adapter cable to convert 3.5 mm stereo audio to a pair of RCA phono plugs to make the analog connection.

I am having the exact same issue. It was fine one day and then stopped the next. I have tested the cables they are fine...its like the port/jack is simply not working. I thought perhaps dust or fibers had gotten in there so i blew it out with some canned air and that didnt help. I am thinking of opening up the box but am not sure what to look for.
