Can someone please add support for the onboard microphone to armbian for the Lite2?!

It is missing in armbian-config, there is no h6-analog-codec.dtbo in /boot/dtb/allwinner/overlay

The microphone is wired up the same way as on the other h6 boards.

 

Thank you very much!

Armbian is a community driven open source project. Do you like to contribute your code?

It sounds to me like you are maybe half way there already?

 

Patches welcome.

in that image "OrangePi_lite2_ubuntu_xenial_desktop_linux_4.9.118_v2.0.tar.gz" the mic is working.

Kernel 4.9.118+


If you want that feature X works in modern mainstream based Linux kernel, it has to be developed / ported. Takes a lot of efforts, time and money ... year(s) to get to some usable level while some features never get attention and are not covered. Feature coverage looks like this: https://linux-sunxi.org/Linux_mainlining_effort#Status_Matrix

 

We don't provide images with those private kernels since its difficult to boot them with open source boot loaders. Generally we do avoid investing our time into closed / proprietary source stuff, which stock images (where mic is working) are made from.
