My son has just bought a samsung SM940MW 19" LCD, but we have no sound when using the Microsoft VGA lead. We have tried using the component lead and the sound works through that. I have made sure that the phono plugs are correctly inserted but have come up with nothing. I would ideally like to use the VGA lead as it has a vastly superior picture to component. We have set the sound to analogue in the xbox sound settings screen. Any ideas guys and gals? Thanks in advance.
