I have a Sony STR-AV880 A/V Receiver vintage 1990s or so. It doesn’t have a dedicated pre-amp out for audio but does have RCA out for a 3 channel (Red/White/Yellow) A/V cable. When I connect the Red/White (L/R) line out to line in on PORT, there is no sound. Was on the line with support and after a considerable amount of time working through troubleshooting with me we narrowed it down to issue between SONY OUT and PORT IN. (yes, we tried alternate cables). They suggested contacting Sony, and I’m thinking anyone in Sony’s support department wasn’t even born when this receiver was made let alone still support it. Was ready to give up when I reconnected the PORT to my BOSE Wave Radio. Thought I would try using connectivity in both directions instead of just using the WAVE as a speaker for the PORT. Once hooked up, no sound from WAVE. It worked yesterday just fine. Only difference was that both input and output were now connected between BOSE and PORT. Just for kicks, I unplugged the cable connecting WAVE OUT to PORT IN and the WAVE now produced sound from PORT just as before. Got me thinking, but can’t get my head wrapped around what is going on. Any thoughts? Could this be a clue as to why I can’t get the Sony OUT to PORT IN to work?
