I have a 5.1 HTIB. I also have an infant, so at night, I want to use my wireless headphones. There is no headphone jack on the receiver - and the only outputs are for the 5 speakers. How am I going to get sound to the wireless transmitter? The transmitter simply requires that I hook up a L and a R anolog sound cable. I thought maybe I could splice into the front L & R speaker wires, but I don't think that is going to work properly because voice comes mostly from the front middle speaker. What I really need (I think) is a switch box of some sort that has a headphone jack. That would do it. Any ideas on a way that I could accomplish this? Can I do it by splicing into the speaker wires?
