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!

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

 

Patches welcome.

Afaik no driver yet, so overlay won't help.

Dear Igor,

 

thank you for your reply. Is there any other H6 based OrangePi with a working audio-codec?

One driver cover all H6 boards.

Ok, at least I tried

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.

i don't prefare blobs either, i'm here trying to find an open source driver for H6

What i found so far is this http(s)://github.com/SoCXin/H6/tree/master/linux/kernel/sound/soc/sunxi/sunxi-snddaudio.c

That's from BSP kernel sources and can't be used as-is on mainline, which is what Armbian uses.

There seems to be a driver available now:
