I have a LG bluray reader which comes with a home cinema thing and a samsung Tv, but i'm not really using that bluray reader since i have a roku device.I'm trying to get the bluray's audio working as my "main" audio device with my roky device. To summ it up, i wanna get the home theater sound from my lg device to work as an external audio device for my Tv? I'm not good at explaining rip, i hope you get what i mean .
