Just installed this on a Minix U9, everything's working except audio passthrough.
Since my receiver don't support HDR I have to connect the Minix directly to my TV, and then I'm using an optical cable to my receiver.
And the sound is working in Kodis GUI. I have three audio devices to choose from in "Audio output device" See below.
But down in passthrough, the audio device is greyed out, and I can't choose, HDMI is pre-chosen and I get no sound at all.
Just for the hell of it, I booted the Minix into Android and launched Kodi from there, and the only audio track available was "android audiotrack" on both regular audio device and passthrough device, and from there 5.1 passthrough is working!
I've also made sure not to enable Sync to display, since I know that disables the passthrough.
How can I get 5.1 passthrough working in Libreelec using an optical cable, since it working in Android on the same hardware it should work in Libreelec as well? Any ideas?
Thanks!
