Hello, I have an I Mac computer that I want to connect to my RCA HD tv. I have run an HDMI cable from the computer to the HDMI input on the TV...I get the video, but not the sound.on the tv..I was told to connect a wire from the earphone port on the computer to the earphone port on the tv, but there is still no sound. Can you help?
If your TV doesn't have the green 1/8" size audio input (same size as an average headphone jack), then get a 'y-cable' that goes from your computer's headphone output to a red and white 'RCA' type connector. Your TV almost certainly will have one or more of these red and white audio inputs.
