And I think you are doing a wonderful job. For the purpose I am using the OPi0+2, a debian-like setup is too bloated, so my rootfs comes from buildroot. However, it is my experience that the kernel and uboot I get from Armbian are much more stable, so I use those. Also when I want to figure out how something works (for instance, analog audio ) I immediately revert to Armbian.

OK, I come from a time when 1.3.17 was the stable kernel version and Slackware was the distribution of choice. I have done my share of kernel hacking over the years, but... device trees and overlays are still magic to me. It turns out I had to seek my answer in that corner: audio-codec had to be enabled in armbian-config (which changes the overlays in armbianEnv.txt).

It seems I did not look properly when looking up which versions (bullseye, buster, etc) are supported for this one. I may have ended up on the wrong page and concluded 'buster' was the safest one. Now, browsing on armbian.com I see that 'focal' is the first choice and 'buster' is not even mentioned. I am going to build focal now. This will not give me a different kernel, though.

When searching the forum on this topic I find a number of hits saying the mainline kernel does not have support for the SOC codec, but these topics are kind of old and I find it hard to find the current status. In the past I have been able to use the onboard audio codec. However, I have been forced to upgrade and I now find that with the kernel I get from Armbian, I do not see the audio (ALSA) device nodes for the codec, only for HDMI. When looking at the kernel configuration, it should be in (SUN8I_CODEC and SUN8I_CODEC_ANALOG are both 'y'), but alas. Does anyone know if and how I can enable the audio codec so I can have analog audio output? I built Armbian myself, using: This (last) commit: commit 5f2e23e9081104653093633f34ce716a46ac46f7 Author: Piotr Szczepanik <piter75@gmail.com> Date: Wed Sep 8 09:54:06 2021 +0200 Disabled hs400 on Helios64 (hopefully only temporarily) (#3126) This command line: ./compile.sh BOARD=orangepizeroplus2-h3 RELEASE=buster KERNEL_ONLY=no KERNEL_CONFIGURE=no BUILD_MINIMAL=no BRANCH=current This resulting /etc/armbian-release: # PLEASE DO NOT EDIT THIS FILE BOARD=orangepizeroplus2-h3 BOARD_NAME="Orange Pi Zero Plus 2" BOARDFAMILY=sun8i BUILD_REPOSITORY_URL=https://github.com/armbian/build BUILD_REPOSITORY_COMMIT=5f2e23e90 DISTRIBUTION_CODENAME=buster DISTRIBUTION_STATUS=supported VERSION=21.11.0-trunk LINUXFAMILY=sunxi ARCH=arm IMAGE_TYPE=user-built BOARD_TYPE=conf INITRD_ARCH=arm KERNEL_IMAGE_TYPE=Image DESKTOP=xfce BRANCH=current

I see Igor took it to the forum, saves me the effort in finding out in which sub forum it would fit best. Some more info: Host is a 64 bit VirtualBox (allocated 2GB RAM, 4 CPU cores, lots of swapspace) "Ubuntu16.04.3 LTS Xenial Xerus" - Release amd64. I have uploaded the logs to http://www.hauntedlantern.com/logs-05_11_2017-17_24_33.tgz . On my work laptop I did exactly the same and there it doesn't fail.
