Hello, me and my father are trying to set up our surround sound threw the direct tv so we can watch it with surround sound. It works with the main box because it has the component cords in the back but my direct tv box does not, only a hdmi a usb and a digital audio. Now the way we had it set up threw the main box was running an hdmi from our tv and another from the direct tv main box it's self into our surround sound receiver and we realized we forgot about sound and plugged in the red and white audio cords from the main box to the receiver and Walla it works fine but I can't do that with mine because my direct tv box doesn't have the component cords or patch cords whatever you wanna call them. So do I have to buy an adapter or what? If so, tell me which, please. Thank you
