I used armbia-config to install an edge kernal linux-image-edge-rockchip64=25.2.2 v6.14.0-rc4 this resolved my hdmi issue on all my monitors listed in my previous reply

@Werner something I noticed with testing Armbian_25.2.1_Orangepi5-plus_bookworm_current_6.12.13_xfce_desktop The HDMI display would output on a 4k display but did NOT display any output on other various resolutions 27" 1440 , 34" 1440p ultrawide, or 2560x1600 portable monitor

I'm waiting for the HDMI part of the audio patch to drop. There is currently discussion going on about the Audio in a private chat, concerning 6.12.y and up, but I haven't seen consensus yet. Once its reached, I will drop in the nodes. This could take time.
