My TV has damaged a HDMI input....I wish to use component RGB cables...Have a great picture...no sound...I hookup RCA red-white inputs next to component inputs-no sound..Hopper seems to have a digital out audio out only...Must I use a special digital wire and if so what type of ends..My TV digital input is a small single hole almost like a 9mm stereo or headphone input...The hopper has an odd looking square style input with a gray center...I had my TV hooked up with RGB cables for years using the old style Dish DVR and Red-White RCA cables for audio and it worked fine..I would appreciate your help-thank you
