I'm pretty sure they imagine to send the signal that's specified in the specs and I mentioned - Netflix/Prime use a Dolby Digital+ (EAC3) stream which gets output from the Chromecast and your box most likely doesn't support. Not sure what your BR player can do, but it most likely doesn't send that. Complaning that Chromecast doesn't support outputting a signal in a format compatible with your other hardware is fine, but that does not mean it doesn't support 5.1 output at all.
