If I disregard the unknown Bose you can try the usual setup which is:
Source -> Receiver (for sound) -> HDTV (for video.)
This wipes out the use of the tuner or apps unless your TV has an Optical out that is not broken.
We've broken the audio output on our tv while taking it off the wall and moving house. I'm looking for an alternative way to use a Bose sound system. I already own a few specialty weird cables so any advice would be great.
