optical cable from tv to bose system
I have hdmi connections from both the cable box and and apple tv into the tv. The optical cable is from the tv to a Bose system. The cable stations broadcast in 5.1 apple tv movies only in 2.0.
I called Apple support and they told me it will only play in 5.1 if the optical cable is run from the Bose system directly to Apple TV.
