2. After a factory reset I installed Kodi from the store, which appears to be Jarvis. I installed the wrapper and this is showing in the Kodi directory. I've changed the audio options in Kodi to passthrough and yet I only get vanilla DTS and DD and not HD audio which my receiver is capable of. I am playing files over the LAN. In the Kodi passthrough options there was only "Dolby Digital (AC3) Capable Receiver" and "DTS Capable Receiver".
Any ideas?
If you are using the wrapper Kodi audio settings don't make any difference. They are only for Kodi internal player (dvdplayer) and, since audio is 5.1 channel max with kodi internal player, the settings you see are correct.
Are you sure the wrapper is correctly installed? If you navigate to a video file in Kodi and press remote menu button do you get an option called 'play using..'? This gives you the choice of wrapper (default) or DVDplayer.
If the wrapper isn't installed then reinstall it by exiting Kodi then, from Q10 Pro home screen, going My Apps - Wrapper, and setting to wrapper playback.
The other problem that might cause no 7.1 audio is incorrect audio settings. Wrapper / himediaplayer audio settings are controlled by main system audio settings. So go Settings - Playback:
HDMI Output: RAW
HBR Output: RAW7.1
