Ok so a quick update. I can get audio passthrough to work inside of Kodi with the Emby addon but not outside of Kodi with the Emby app so it does work. Hopefully they can get it to work properly without having to use Kodi.
I just received my z12 and while it is a nice box, the audio passthrough issues are a deal breaker for me. Is this being worked on or do I need to return my box?
