No, just tested if it worked.
I would like to use both HDMI outputs for video (a second display for webcams etc.), currently it's not possiblle but audio can be switched.
You can change the audio output in Kodi through Settings / System / Audio / Audio output device.
Hi
Sorry to continue an old thread.
This is actually what I need from my HTPC. Onboard HDMI for audio to AVR (non-4K) and video to my 4K TV from external GPU HDMI.
But I'm running LibreELEC 10 x86_64. Do you know if it works on that version too?
