Hi, in your latest version, miccrophone still cannot work, do you have plan to fix it?

Actually i have not tested it.
Someone with alsamixer experience should pick it up and find the best configuration for the output/input sound. I will have a look at this (don't expect it soon), but if you share how far you have gone with your configuration maybe others can help.
It is also important to test if microphone is working with Android, can you test with Android?

Thanks for your answer.
I have little experience about alsamixer, so I just configured like your guide and use audacity to test it. It can play music normally but cannot record any sound.
I also used android to test it. Microphone can work.

Below is modified things like your guide.
pcm.!default {
type hw
card 1
device 0
}
ctl.!default {
type hw
card 1
}

I modified some configuration using alsamixer, and now I can get sound from MIC1(microphone standalone), but MIC2(microphone with 3.5mm audio jack) still can't get any sound.

Paste asound.state below.
