I have a 46" LG TV with minimal connections on back. One coaxial, one HDMI, yellow-blue-red-white-and another red A/V connections. My PC has the front and back 3.5mm pin speaker plugs and HDMI- VGA and DVI connections. I tried HDMI but that only gives me video. I had to plug a pair of Logitech S-120 speakers to the back of the pc to get sound with the HDMI for video. Is there a way to just use the TV speakers for TV and when not running TV, just my PC without having to switch things out. If I play a PlayStation game or play a movie on the DVD player through it the TV speakers work and they are both connected to the TV through the red,yellow and white A/V cables.The TV is only about a year or so old. I also tried using a VGA cable to the back of the PC with a VGA to HDMI adapter on the back of the TV and nothing.
