HDMI noise on Rock64
#1
I unplugged my Odroid N2 because there's no acceleration for video, and plugged in my Rock64.  Sound is currently being done over HDMI because that's what worked best with the N2.  Actually my monitor has an audio output where it splits the sound off and feeds it out an analog jack to a pair of computer speakers.

It works fairly well if I'm playing a movie or something (haven't  tried a sound file).   But when nothing's playing there's this sound that's like digital noise, like if you get a radio too close to a computer.  It stops if I turn the monitor off.  It's like a high impedance input is sitting there open and picking up junk when nothing's being played.

Using Debian Buster from an Ayufan image, freshly loaded a few days ago.

OK, I get it with a Raspberry Pi 3B too. But not with the Odroid I think. Maybe but I didn't use it to watch movies like I can with the Rock64 and RPI. Yet I set up HDMI sound as the default on the Odroid.
