Audio setup issues – Minix U8 Plus

I’m not sure what the audio settings need to be for minix and kodi in order to have the audio play through the sound bar.

Here is my setup: HDMI directly from Minix to sound bar. HDMI (ARC) from sound bar to TV. Could also do HDMI from Minix directly to TV, shouldn’t matter either way though. TV and sound bar are both brand new: LG UH8500 & Bose Soundtouch 300.

I’ve tried changing the settings a bunch of different times i.e HDMI passthrough/HDMI & passthrough, enabling passthrough in Kodi, and so on.

I’m running the latest version of Kodi (as far as I know).

If anybody can help it would be greatly appreciated!!

Thanks
