I am trying to hook up my HP pavilion p7 desktop, running Windows 7, to my sony bravia tv. "Integrated Intel" graphics card. Card has two dvi outputs, no vga or hdmi. I used a dvi-hdmi adaptor, hdmi cable, hooked up to hdmi input on tv. Picture comes over fine. But I can't get the audio to play through the tv speakers. hdmi input section on back of tv has left-right rca audio inputs. Computer has 3.5mm audio ports, so I used rca-audio adaptor to connect pc sound output to tv sound input. But all is silence. Anyone have any ideas? I'm not especially tech-savvy, so don't laugh at me. DZ
