Hello!
I've updated yesterday from latest stable OpenELEC to LibreELEC 7.02 on an Intel Nuc.
The upgrade was really easy by following the WIKI documentation and i had no big issues.
The only thing i had to adjust after the upgrade was the audio setting by activating the passthrough option of KODI to get Audio working on my Samsung TV connected via HDMI.
With that option activated audio was working for movies.
The only thing what is still not working is GUI Sound. I tried already to change to another GUI Sound or disabling/enabeling it but i still do not get any sound from the GUI itself.
I use the AON Skin but the problem persists if i change the skin.
thx
