[MOD] [MM] increase audio for headphones

[gabripranzo]

Hi all I just bought a Note 4, immediately updated to Marshmallow, and I noticed the headphones volume was really lower than in my Note 2. I gave a look in Xda but didn't find any mod to increase audio level, so this is my solution. Of course you need root access..

Go in /Etc folder, copy default_gain.conf file to another directory and open it (I used Es note editor, which is bundled with Es file explorer).
Find the following lines:

Modifier "Normal" {
SupportedDevice {
"Headset Out"
}
Enable {
{ "Noise Gate Switch", 0 },
{ "HPOUT1L Impedance Volume", 113 },
{ "HPOUT1R Impedance Volume", 113 },
{ "HPOUT1L Input 1 Volume", 32 },
{ "HPOUT1R Input 1 Volume", 32 },
}
}

Modifier "Normal" {
SupportedDevice {
"Headphone"
}
Enable {
{ "Noise Gate Switch", 0 },
{ "HPOUT1L Impedance Volume", 113 },
{ "HPOUT1R Impedance Volume", 113 },
{ "HPOUT1L Input 1 Volume", 32 },
{ "HPOUT1R Input 1 Volume", 32 },.

All you have to do is to change the value in the strings
{ "HPOUT1L Input 1 Volume", SET THE VALUE YOU LIKE },
{ "HPOUT1R Input 1 Volume", SET THE VALUE YOU LIKE }

I changed it into 48 and it's enough for me, so my lines are as follows

Modifier "Normal" {
SupportedDevice {
"Headset Out"
}
Enable {
{ "Noise Gate Switch", 0 },
{ "HPOUT1L Impedance Volume", 113 },
{ "HPOUT1R Impedance Volume", 113 },
{ "HPOUT1L Input 1 Volume", 48 },
{ "HPOUT1R Input 1 Volume", 48 },
}
}

Modifier "Normal" {
SupportedDevice {
"Headphone"
}
Enable {
{ "Noise Gate Switch", 0 },
{ "HPOUT1L Impedance Volume", 113 },
{ "HPOUT1R Impedance Volume", 113 },
{ "HPOUT1L Input 1 Volume", 48 },
{ "HPOUT1R Input 1 Volume", 48 },

Now you have just to backup your original file, then copy the edited one in /Etc folder, set permissions to rw-r--r-- (I use root browser which is free) and reboot.

You headphones audio is much higher now

Hye you should share your own .conf file.

File added. Anyway maybe the mod adds a little bit of digital noise, even if I'm not sure about it. Please report your opinions.

hmm... damn. sounds fantastic but won't work for my bluetooth headphones ... any recommendation where to change those values? thanks in advance!

edit: got it after reboot it was neccessary to decrease and increase the volume at the headphones. now the maximum is quite enough thanks mate.

Finally Found This!!! Thanks Alot @gabripranzo , i tried something different i've read somewhere the first row that contains "Headphone" & The 1st row that contains "Headset Out" in it i changed the value there of both (Left & Right) 113 to 125 & It works perfectly without any music stops! This Works better IMO. than the bottom lines that has 32 bec. When i changed the values there to 44 music always stopped at max volume.

I'm glad you found the right solution for you. I think music stops when you overcharge the amplifier, I experienced the same thing with my Note 8.0 tablet with Boeffla kernel: it allows to tweak the volume, but if it's set too high (I did it because I have high impedance headphones) music stops, probably to avoid damages.
In the end I bought a USB DAC/amp to connect to my Note 4 and I'm very happy with it
