Sorry, but why do you want listen to HD audio on a TV's speakers anyway? There's absolutely no benefit from this at all compared to the SD audio tracks. As I've wrote TV's don't support HD audio. XBOX probably also sends just SD audio, and Netflix does absolutely sure. DD and DD + Atmos is still SD only, but True-HD is HD, that's why. I have already wrote your best choices. If you really don't have any other SD track in the video, than set the output to LPCM and hope that it mixes down the HD track to 2 channel SD LPCM.
You need a capable AVR and speakers to get (also the benefits) of HD audio.
