RPi 4B / 2GB
After upgrade from LE11 nightly 20220528 using LibreELEC - Updates - Available Versions menu I was not able to get the HDMI audio output anymore.
No GUI sound, no LiveTV sound. Tried all available HDMI targets - no way. The analog output worked. Tried to force defaults in Audio properties without any positive effect.
Also sometimes after some menu selection I got black screen during Live TV watching, stopping the channel helped to get the GUI menu back .
Reverting back to 20220528 fixed the issue.
