[SOLVED] HDMI Audio - Can it be muted/disabled?

[Rascal]

@TooQik

I’ve gone back through every menu and setting option I can find while in Expert mode but I’m unable to find anything related to muting HDMI audio. Is this an extra add-on that needs to be downloaded, or should it be installed as part of the default load?

Should be by default to my knowledge on Expert mode. Make sure you are not using any custom skin which prevents you seeing the options.
Settings → System → CoreELEC and under Audio, Disable HDMI audio output.
