Hi folks, Can anyone confirm which if any boards / cpus have functioning HDMI eARC suport? I've seen OrangePI 5 mentioning they have support, but it's unclear if the software support is there in any way; i assume all rk3588 (or likley hdmi 2.1 certified) boards will have hdmi (hardware) support. Similar with Khadas VIM3L or VIM4; hardware support is mentioned w/o any clarity on the software support. Thanks!
