I have a new Raspberry Pi 4 and I can not get any sound from HDMI. I get no sound from videos or from MP3s. I have GUI sounds enabled, nothing.
I set output to both HDMI & Audio Jack, the audio jack works.
I know there is no problem with the HDMI cable, I tried running Raspberry OS, and I was able to play a MP3 thru the HDMI cable.
I have LibreELEC installed on a Chromebox. I compared the guisettings.xml files and I didn't see anything obvious.
Also I picked up a cheap Westinghouse TV on Black Friday. I get no signal when I connect the Pi4 to it. I tried 3 different cables, nothing. I get output when I connect my laptop to it
