Has anyone tried to do this?
The problem I’m facing is that the Ubuntu flavor as installed by Khadas only offers built-in analog output and the HDMI outputs are not seen/configured. I did spend already some time to change the configuration of pulseaudio but with no succes.
The hardware supports HDMI multichannel output since when installing coreelec on the same SBC, the HDMI multi-channel output becomes available.
Any hints?
I tried to move to pipewire with and without wireplumber, but with no luck.
