I have a toshiba 42X3030D LCD. If I connect my graphics card (MSI 7900GTO) to the TV via the VGA cable, it works okay and i can get sound from the soundcard to the audio-in photo ports no problem. The problem im getting is that i have recently bought a HDMI - DVI cable (because I want to watch HD movies playing on my pc in HD.) - I picture transmits okay, the problem is that the TV has seemed to stop picking up the audio from the computer. Ive tried a lot of cable swapping and googling but to no avail. Any ideas ?
