It doesn't necessarily have to go through the BOSE... I would be fine with just getting audio to connect through the TV. The BOSE has audio inputs for TV, AUX, and CBL/SAT.... currently I have a directv DVR box that is connected to the BOSE and sound comes out fine... but when I switch from Video 6 which allows television to play then go to Video 7 (Firestick) I get the video to play fine but there is no audio.
