Hopefully a simple setup change is required for a problem that I couldn't figure out after working with it for a couple of hours.
Audio: Bose Cinemax 520
Everything is working perfectly except for when I connect to Netflix or Amazon. The sound insists on coming through the TV speakers instead of being routed through the Bose system. The result is audio coming through the TV speakers for Netflix and broadcast TV coming through the Bose at the same time.
