Hi,

I try to get MIC0 port to work in Ubuntu 18, but I can't find any hints how setup Kernel/Linux to find Internal Mic port. I have connected AIO-3399J CON2_2D0 (MIC0) same kind mic wich is in AIO-3399EC board. Two pin, positive and negative. I try get some input with PulseAudio, parecord, but I still cant get any audio input.

Do I need to make changes to kernel files? I use "rk3399-firefly-aio-lvds.dts" devicetree. Both speakers work now in Ubuntu 18, Thanks for fix it!


BR,
Pekka

I try to figure out that reason why mic and mic jack doesn't work, but nothing wasn't help. I try to search kernel dts settings from Android and Ubuntu dts-files and test different options, but no luck. So i need to use USB audio card to get audio in... I have 16pcs AIO-3399J devices...

Because of the feedback loop, I believe it is very important to always think about what you did and how you could improve it snow road 3d.  That's the best piece of advice I can think of: always question yourself and think about how you could do things better.
