I just got a new LG 82UM80 with new sonos play bar and surround speakers. Trying to figure out best option for running 5.1 from nvidia sheild pro. TV gives me options for bitstream and pcm. Also has Dolby atmos grayed out but it shows enabled. Getting surround when I run YouTube dolby 5.1 tests.

Again just trying to find the best option. Manuals and internet not really giving clear options on best set up.

Thank you.

Select the sound out optical setting and set the port to 'Pass through’ if it doesn’t then work for you, set it to 'auto’.
