Hi!
Have you been able to solve this issue?
I got the same one, and mixer_path is also the same.
I've spent a lot of hours trying to boost mic volume but without luck...

doing some research, I found that I have to edit the mixer_path.xml file located in "/system/etc/mixer_path.xml" and edit some values to raise up the mic gain, but I don't unterstand what I have to edit 
can someone help me?
this is my original mixer_path.xml file:
