I have the Moto E 2015 LTE (single sim eu version) and had a hard time hearing what the other person were saying during calls.
This was a problem when trying to talk "normally", with the phone against my ear. (no headphones or speakerphone)
After some googling and testing i finally found a way to fix this.
This fix requires a working recovery (i used TWRP), but rooting is NOT required.
(rooting disables my camera)
There is a file called mixer_paths.xml located in /system/etc/ that contains the answer to my problem, witch im now sharing with the rest of the world.
I made the following changes:
(line 23-25)
<ctl name="RX1 Digital Volume" value="92" /> (was 84)
<ctl name="RX2 Digital Volume" value="92" /> (was 84)
<ctl name="RX3 Digital Volume" value="92" /> (was 84)
(line 34-35)
<ctl name="DEC1 Volume" value="92" /> (was 84)
<ctl name="DEC2 Volume" value="92" /> (was 84)
(line 50)
<ctl name="Speaker Boost" value="ENABLE" /> (was "DISABLE)
(line 486)
<ctl name="ADC1 Volume" value="8" /> (was 7)
(line 493)
<ctl name="RX1 Digital Volume" value="90" /> (was 84)
(line 504)
<ctl name="ADC1 Volume" value="8" /> (was 7)
If you are rooted you can edit the mixer_paths.xml in a root file manager, but you will have to mount /system as read/write first. You probably will still have to boot into recovery and wipe cashe.
Google is your friend for such endevours.
Included below are two files, the original one (default) and the modified version with the above mentioned value changes.
Install instructions:
To install, reboot your device into recovery mode and mount system partition.
Using the recovery mode file browser, find and rename the current mixer_paths.xml (change name to mixer_paths.xml.bak)
Connect your device to your computer and launch a ADB terminal.
Make sure youre in the directory where you unpacked the mixer_paths.xml
type these commands:
adb push mixer_paths.xml /system/etx/mixer_paths.xml
Use the recovery mode to chmod the new file, chmod 755 should work, but i did chmod 777.
Use the recovery mode to wipe cashe.
reboot your device.
Restore instructions
To restore to original, boot to recovery, delete your modified mixer_paths.xml file and rename mixer_paths.xml.bak to mixer_paths.xml.
When youre done, wipe cashe and restart.
In case you deleted it instead of renaming it, download the default one below and follow the install procedure.
A warning; too high volume will damage your device and boosting the volume might degrade your audio quality.

General help Moto E
I have tried Google but I'm still lost (sorry). I am using TWRP and my phone is a XT1527 Moto E (2nd) Surnia 2015, so can I use your file or should I edit the existing (phone) file?
General: Do I use TWRP on my phone (in recovery mode) to mount the System on the phone (SD or internal) memory?
Thanks in advance,
Glen

Will this also work on epic rom?

Dont know
I would advise against this method, as it more or less disconnects audio configurations completely.
You are better off increasing the /system/etc/mixer_paths_tasha.xml handset ctl's digital volume slightly.
Probably not a good idea to go over default 84, as there may be good reason for Xiaomi setting this as low as 80.
Code:
<path name="handset">
<ctl name="SLIM RX0 MUX" value="AIF_MIX1_PB" />
<ctl name="SLIM_0_RX Channels" value="One" />
<ctl name="RX INT0_1 MIX1 INP0" value="RX0" />
<ctl name="RX INT0 DEM MUX" value="CLSH_DSM_OUT" />
<ctl name="EAR PA Gain" value="G_0_DB" />
[B] <ctl name="RX0 Digital Volume" value="84" />[/B]
<ctl name="PIEZO Port Switch" value="1" />
</path>
Strangely enough when I flash this the calls are perfectly hearable but all of my system sounds / alarms / ringtones are not working anymore.
Does anyone has a solution for this?
EDIT:
I did a 'upgrade' using the latest LOS rom (the same I used) and now the in call volume and the sound works... without flashing the above zip...
Strange but glad it works again

The file can be located in /system/etc or /system/vendor/etc (in my case RR 6.0.0 - G900F)
open up the file and edit the values by your needs after editing save it,
set the permissions to -rw-r--r-- (644) and reboot your device
this is my modified version of the original file (just the microphone part)
the values are normaly aroud 85-93...and that is pretty low
Down below the bold values are the ones that should be modified

I've got the same problem on an Galaxy S5 (SM-G900W8 ) with crDroid. I think both ROMs come from Lineage OS and although I haven't tried it I'll bet Lineage 15.1 has the same problem.
I'd like to give it a try, but I can't seem to modify the file. I mixer_paths.xml in /system/vendor/etc, but when I try to edit it I get a message that it's a read only file system.
Permissions on the directories look OK:
/system 755
/system/vendor/ 755
/system/vendor/etc 755
I also tried to create a file with "touch" in /system/vendor/etc and that failed-confirming the whole directory can not be written. Can someone please tell me what I'm doing wrong.

This is my config, and its work. I changed All 3 paths with "headphones" in name
Hi everybody
This method has been tested and working but you do at your own risk. I will not be held responsible for any damage
To do this your phone must be unlocked and rooted :
*** I use Root Explorer to do this ***
Go to:
odm/etc/audio/hi6403
and open the file named "mixer_volumes_MANHATTAN_normal.xml"
find the lines :
<path name="media-headphone" >
<ctl name="S1 IL PGA GAIN" value="0" />
<ctl name="S1 IR PGA GAIN" value="0" />
</path>

replace the zeroes with higher value (7 works perfect for me)
Save
Reboot
Enjoy
hello guys sorry for my bad English, I bring this little contribution to the forum.
I have p9-Lo9, but the sound is a bit low, I come from an m8 htc and I like it to sound louder than normal, So look in other forums, the way to do it without any results, only exists for the p9 lite, I found a way to do it without using applications, I managed to modify a file of the system that allows us to alter the volume standards,
requirements
have the rooted phone and a file explorer that allows us to enter the system folder
1- for android 6
Download the file mixer_volumes_EVA android 6 or 7 and copy it to system / etc / audio / hi6402.
2- for android 7
enter the root of the whole system, find the folder product / etc / audio / hi6402.
decompress the downloaded files and move them, that's all maybe in the future it could be in oreo, at the moment it does not work modifying the file

For some reason (?) I had problems to make a copy of the xml file. Every time I tried, it copied but as an empty file, 0 B.
Eventually, I copied to SD card and back, to get a correct copy, 80,17 KB
