A good TV In card?
 

Looking to build a new PC and I'm trying to find a nice video in card. I hook up a directv receiver to the card via coax etc. I need something that I can run sound off of into my onboard 5.1 sound. My little cheap card has a sound cable taht comes off of it, that I run into the 5.1 but if I want full 5.1 when I play games etc I have to unplug it and plug the speakers back in.

Is there something I can get so I don't have to change cables, and have everything hooked up and play sound correctly no matter if I'm playing a game and need 5.1, or if I'm using DirecTV.
