Best connection would be all sources via HDMI to Bose. Bose HDMI out to one of the TV HDMI inputs. The Bose doesn't seem to have ARC (audio return channel) over the HDMI conncection so you If you use the internal tuner or smart functions of the TV you would also need to add an audio connection from the TV to the Bose. You might need a DAC to convert optical audio out to analog since the Bose doesn't have an optical input.
