Hi,
I have an odroid n2+ box with coreelec installed, and a sonos arc sound with the last update 12.2.
When trying to play a movie the box crash. I tested the box directly to the tv sound and works.
On the coreelec i have configured the audio output device:
AML Augesound, HDMI ch PCM.
My sonos arc is connected to my tv on the arc hdmi port.
I do not know what to do more.
PS: Also, i tried a nvidia shield and it works, on kodi.
