My Sonos app is showing that everything I play via my External HDD through my android TV is playing in Dolby Digital plus 2.0. I'm positive it used to play 5.1 with video that supported it and I have the speakers. I've enabled pass through on my TV and Kodi and checked a film on Netflix to see if it shows up as Atmos or 5.1 and it does. I'm also using the Arctic Zephyr skin if that causes any issues. Can anyone help?
