I would like to use the ODROID C2 as a media player. The video and network capabilities are looking quite promising. I can't find much about the supported audio modes. Does anyone know if audio passthrough via HDMI is supported? Does the platform even need to support it or is it just a software thing and Kodi can do it anyway?
