By the way, it's a shame the old method of forcing the bit card number via /etc/modprobe.d/alsa.conf didn't work on Armbian. options snd_usb_audio index=0 options sun4i_codec index=1 options snd_hdmi_audio index=2 alias snd-card-0 snd_usb_audio alias snd-card-1 sun4i_codec alias snd-card-2 snd_hdmi_audio That's why I was looking for a way to disable these additional audio codecs and HDMI, but maybe it's because snd_usb_audio, etc., aren't loaded as modules in the new kerne

Well, with the new image there was some progress, but I will give up for now. I will look for an SD card and try again using it. I’m confident that I will finally succeed in this operation.

I don't know the names either. I suggest to look at the original device tree by decompiling it: dtc -I dtb -O dts /boot/dtb/allwinner/whateverthenameofthezero3devicetreewas.dtb

@Maberikku Great! @humanus Nick said you hit a kernel error on 6.6. Can you paste the details here.
