Hi, I was using RetroPie through HDMI and it runs perfectly. I was using it in the living room TV because in my study TV there was no sound when using the Pi through HDMI.
Recently I moved all my gaming consoles to my study and I want to connect the Pi to my TV in there, but again, there’s no sound through HDMI, so I tried connecting it through RCA. The problems I encountered are 1) There’s a buzz in the audio and 2) The game images stretch all the way to use the whole space of the TV, which I don’t like. I want the games to have their original aspect ratio. It works perfectly through HDMI, but somehow the image gets stretched when I connect it through RCA cables.
Another issue I have is with the video quality I’m getting. The images don’t look as sharp, and look kind of washed out.
