@spiderio
Does it causes any disortions to the sound if you increase the volume or the sound quality remains the same?

please don't quote the OP
as long as the volume value is not higher than 93

 

[paratox]

i have already tried this but it had no effect!
there is my "old" thread: http://forum.xda-developers.com/lg-g3/help/making-headphone-louder-t2812892

What values are you personally using for each lines?

I've felt like I need more volume from the speakers, so thanks!

I'm having issues with opening the mixer_paths with root explorer, however - I cannot open the entire file because it says it's too big. I'm also unable to find the file through the file manager that comes stock with the phone.

It has effect on my g3 D855 10A.
I write the wrong file
The correct one should be mixer_patah_qcwcn.xml

Sorry I got excited and write the wrong file name

Try it again
Set the speaker to 90 to try the effects

You may want to update the OP with the correct path then so people don't keep trying the wrong one.

When I see the OP it says this

. backup your original mixer_paths_qcwcn.xml (copy to sdcard, rename to mixer_paths_qcwcn2.xml, etc, etc)
3. open mixer_paths_qcwcn.xml

Your two posts stating the correct path is

The correct one should be mixer_patah_qcwcn.xml

Try editing the mixer_paths.xml

I'm using International D855
And try to change the speaker value to 90
If it works just let me know

I will change the OP for D851 version guide
If it works could you send me your mixer_paths.xml

i don't have this file , mixer_patah_qcwcn.xml
but i have this file, mixer_paths_qcwcn.xml and upon checking the lines of those "green" which we have to edit they are the same.

Yeah that's my autocorrect fault
