The sound IN port (headphone to headphone jack type) on Regza works in PC mode when using together with a VGA cable - so I can get PC sound on TV. BUT I cannot get sound to come through when use together with Div x to HD cable in. Is there a setting on the TV to switch it on. It says it can in connection part of manual but doesnt show the settings. It is a Toshiba Regza AV635 32 inch
