Hello I want to connect my PC with new Sony W4500 series TV. PC has DVI out and Stero Jack (3.5mm). I have DVI to HDMI cable, which works fine and transmitting great video. Issue is sound, I have cable 3.5mm headset to Phono (RCA) Cable. How do I get sound on TV: If I change input to HDMI, then there is no audio and if I change it to AV3 (which has phono in), there is no video? Please suggest... Thanks in advance..
