Hi guys! i just got given a Winfast TV2000XP Deluxe for my b'day

well i have installed everything on the cds, winfast pvr stuff! and i have got the picture looking good but cant get the sound!

I have a a7v333 mobo with onboard sound! and i assume that i would stick it in to the blue spot on the sound card (says it in the winfast instructions to put the green on the tuner to the blue on the sound card which i have done.

Now is this blue on the soundcard my line in or what?Does it have a line-in? Do i have to enable anything else?i want sound!!
