if I understand it correctly, LT8619C is responsible for extracting the audio from HDMI output, and the kernel doesn't have support for it. here's the closest thing that I could find: https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/bridge/lontium-lt8912b.c the original Bigtreetech firmware has the sound, will try their image again tomorrow.

same thing with edge kernel: https://paste.armbian.com/orivozogil

I built an Ubuntu current image, as of commit f15f594d0bd4ad1e5d0fa412f1d25120e76e4f9a (Armbian-unofficial_26.05.0-trunk_Bigtreetech-cb1_noble_current_6.18.20.img) and started my newly arrived Pad 7 from it. Things that work out of the box: display, touchscreen, wifi, USB. Not working: LAN is not visible at all (only two wlan interfaces). Also, no audio device. According to schematics, audio is taken from HDMI output, so it should be supported by standard HDMI drivers. Where do I enable it in kernel config? https://github.com/bigtreetech/Pad7/tree/master/Hardware your hints will be appreciated. smartkbd@bigtreetech-cb1:~$ wpctl status PipeWire 'pipewire-0' [1.0.5, smartkbd@bigtreetech-cb1, cookie:3329793852] └─ Clients: 32. pipewire [1.0.5, smartkbd@bigtreetech-cb1, pid:1127] 34.
