Hi!, I have an androd 7.1, 10.25" rooted unit for my bmw f30, I'm trying to raise up the gain of the microphone because in call and in vocal registrations the recorded volume is too low, and adding an external microphone did not resolve.
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:

Nope not really, YouTube is hard to control for stuff like this.

If you want to watch downloaded videos, you can use MX Player to set screen aspect ratio if video is not in our aspect ratio which is 2.39:1 I think.

Hey Fred, is it possible to modify MCU so rear cam stays active for longer?

So i think that you can have success by deleting app ids and updating the list.
You can try it .
I managed to do it as well by updating the /data/local/mapapklst.txt file.

I only struggle with the volume settings of my device. The navigation output from the left speaker is now very loud and when I get a call (it also only comes from the left speaker) the volume is very low although I set the volume in the audio settings to max for calls. Do you have any idea how to set all the volumes correctly?

Recovery mode does not help because it has no hardware buttons to move through the menu.

only way would be via ADB, has usb debugging been activated at some time by you ?

There is one way: if you have Android 7.1 rename px3.img to px3_reset.img, if you have Android 8.1 rename px6.zip to px6_format.zip. Upload to USB flash drive, insert into slot. If you have an SD card inserted, remove it. Connect power to the unit. The factory reset should be complete. Unfortunately I don't have Android 9, so I can't help with it....

But this is not for all MCUs, right? Or is it universal?

In my opinion it has nothing to do with MCU, it's an android daugther board thing: hxxps://github.com/chinesebmwheadunits/chinesebmwheadunits.github.io/wiki/Hardware

however, each android daugther board has its own firmware, eg you cannot use px3 for px6 and vice versa, even if they are mounted on the same MCU !!!

once in recovery, scroll should be brief press of reset, select long press.
Anyway, my platform is NOT px3 nor px6, it's a "newer" snapdragon 625 , not a rockchip. So no way for me with the well known zip in the wild, I need the recovery to format and do a full wipe, or do anyone have the correct zip for snap 625 android 9 headunit?

It happened I set the screenlock pin (my google account is under mdm so I need it) and now the unit doesnt recognize it :/
