Please help!! I have just installed my nice new shiny Twinhan Ter D+A card with the latest drivers and software from the Twinhan website all is working well except that when I turn on the terrestrial reciever I get an echo immediately after any sound or voice. Almost like a ghosting effect and all sound is coming through twice. I'm a bit of a thicko when it comes to these kind of problems so would appreciate any help from anyone. Thanks in advance. Damon
