I have a tv with just 2 hmdi ports , my direct tv box is in one and my dvd/surround in the other . I have a firstick . How can I use my firestick and get the surround sound to work with it ? I bought a splitter and hooked it up on the back of my tv . But can only switch from firestick to dvd on it . From what I can tell , I have no more hmdi ports to hook to anywhere . Im not much on hooking electronics up anyway .Any help would be greatly appreciated !
