This mod will increase your volume output on any LG G2 variant running KitKat 4.4.x firmware!
I've packaged up a recovery flashable zip that will modify /system/etc/mixer_paths.xml on your device and increase the volume output.
Just flash it and you'll be boosted!

FAQ
Q: how do I install this mod?
A: flash it from recovery. You need a custom recovery like TWRP, CWM, Philz, etc.
Q: what devices can this be used on?
A: any LG G2 variant (d800/d801/d802/d803/d804/d805/ls980/vs980)
Q: will this work with my ROM/firmware?
A: any stock or aosp based KitKat firmware should work. If you have troubles, please post here!
Q: is this mod compatible with other audio enhancements (like viper or other equalizers)?
A: yes. It should work with any of them.
Q: does this mod cause distortion?
A: not that I have experienced. If it does for you, please post here! Keep in mind combining other audio enhancers or mods may cause distortion, but you would likely have that distortion just by using the other enhancer or mod alone without this mod.
Q: can you make it louder?
A: this mod should make your headphone volume pretty loud, but if it's still not enough and many people ask for louder I might make a secondary zip to increase it further.
Q: the zip file only has a META-INF folder! Where's the modified mixer_paths.xml?
-or-
Q: can I extract the zip and install it manually?
A: the zip actually modifies YOUR mixer_paths.xml so that it's only changing a few values and not completely overwriting whatever comes with your firmware. Because of this you can only install by flashing the zip.
Q: why did you choose 65 for RX1 Digital Volume and RX2 Digital volume? Why did you choose 20 for HPHL Volume and HPHR Volume?
A: on CyanogenMod (and I believe all aosp based G2 firmware) the highest value that is set anywhere in mixer_paths.xml for RX1/2 is 65. Likewise the highest HPHL/R found is 20. So I applied these values for headphone output which by default has lower values.
Q: what's the difference between RX1/2 and HPHL/R?
A: i believe RX1/2 are the digital volume, and HPHL/R are the analog volume. But I could be wrong.
The idea to modify this setting came from the following threads:
Make sound louder in all KK Roms and LG KK for F320 (update 16/02/14)

That's all it needs.
When you flash the script doesn't replace your existing mixer_paths.xml with a new one, just modifies the one your firmware provides.
Here is the code for the 1.2 updater-binary
Code:
#!/sbin/sh
RECOVERY_SCRIPT_FD=$2
set -o pipefail
ui_print() {
echo "ui_print $1" > /proc/self/fd/$RECOVERY_SCRIPT_FD
echo "ui_print" > /proc/self/fd/$RECOVERY_SCRIPT_FD
}
mount /system
mount -o rw,remount /system
x=''
y=''
sed -i -e "s/$x/$y/g" /system/etc/mixer_paths.xml
ui_print "Digital Volume set to 65"
x=''
y=''
sed -i -e "s/$x/$y/g" /system/etc/mixer_paths.xml
ui_print "Headphone Volume set to 20"
exit $?
Which reminds me I should have changed the print line to also mention the digital volume being set to 65.
Edit: never mind, it does on a different line, it's too early and I haven't had enough coffee yet.

This mod only affects the output volume of the headphones.
I don't think the Bluetooth output can be modified in the same way, but I'll look, and if it can I'll release a separate zip in this thread.

I'll be experimenting with a second mod to increase the speaker volume today. Any volunteers to test?
Edit
Well the first experiment just lead to lots of distortion setting the speaker to 70. The stock speaker volume is satisfactory to me without modifying it, so I was only testing for my curiosity. It seems like ~65 is as loud as the speaker should be set (and it already is on aosp based firmware, and probably stock too).
I won't be making a speaker volume mod unless requested. If you really want it, send me your /system/etc/mixer_paths.xml file.

This mod is amazing made my headphones and portable speaker sound so much better i used to hate ASOP because of the poor sound quality but this boosts it and then some! Ive tried it on a few ASOP 4.4.2 ROMS and works perfect everytime using it on carbon rom atm good work!

Search for "viper for android" install that and you can boost speaker volume nicely.
You can also modify your mixer_paths.xml file to boost speaker volume but viper is much better.

Thanks for your help, but I can't install viper ?. I'll try the suggested modification.

Jonho77 said:

In order to install viper you will have to copy audio.effects.conf from system/vendor/etc to system/etc then vipe will install and work as adverised (provided you also install busybox that is)
For some reason that file is not present in the system/etc folder and it needs to be there as well as system/vendor/etc for the viper installation to work.
Took me some work and help from others to figure that out in a round about way.
Oh and when you copy it make sure you change permissions to match everything else in that folder. You won't regret it, if you have any other problems the guys in the viper main thread are super helpful. or you can ask here and I will be glad to help also.

you can also edit the default_gain.conf files in system/etc

Could anyone tell me which options in the .conf file to edit ?

Why not just install Mxplayer, it automatically allows you to boost the volume, just enable it in the audio settings. imo there is no better player for Android.

Will it boost the volume past the limits set in the default_gain
Also, will it boost the volume of YouTube clips through my headphones ?
( which is what I actually want to do)

[MOD][S6] GALAXY S6 Edge - Headphone Boost(CWM) UPDATE 7!

S6 Headphone Boost Volume Boost ¸¸♬·¯·♩¸¸♪·¯·♫
Hi , this is mod for S6 Edge Headphone boost, made by stalli0nUK recipe.
U need to flash this under CWM
Flash Guide:
Supported model: Galaxy S6 Edge, G925F/I (could work on other unlocked models too, like T-Mobile one
1- Download TWRP v2 recovery |
2 Rooted Galaxy S6 Edge
3 - Reboot recovery.
4 - Flash S6_Volume_Boost_Headphone.zip
You’ll see TWRP 2.8.6.0 on your Galaxy S6 Edge in all its glory. Enjoy!
That’s it. If you face any issues, i am not responsible )
These is just tested on the S6 EDGE, other variants use with caution.
Feel free to ask anything.
Thanks to : stalli0nUK
UPDATE 3
Twrp2 recovery is out with great install tutorial, so folow that and flash headphone zip.
UPDATE 4
I also add mixerpaths xml in post , and u can copy that to system/etc if u have root, just overwrite old file(just back it up first)... and of course set the right permisions for the file 644
Value is 39 which is very loud
If you wanna change on your own this is what u need to change :
HPOUT1L Input 1 Volume" value="39"
HPOUT1R Input 1 Volume" value="39"
Stock value is 32...
Hope this will help a lot of u guys
Link mixerpaths.xml
http://www55.zippyshare.com/v/dyIXkDuk/file.html
UPDATE 5
I attach V40 loudness TWRP file this is much louder than V37 version for anybody who wants louder.
)
UPDATE 6
I Added V40 + Speekers Loudnes V38 (very Loud) )
Also will try to make in call volume mod also and post it later.
UPDATE 7 (High volume notification)
For me best and easiest way to do this is: plug in your headphones turn the volume to max, go to music app , settings , turn smart volume on and u will get a message that (default volume is now 15 bla bla... ) then go to youtube and test it, and voila no more high volume notification
Br

Can I install the headphone boost .zip file with the CWM Root?
Why have I got to install the TWRP File?
One more question:
Can I just use the mixer_paths.xml file and put it into the etc folder and give it rw-r-r- permissions? (When I have root)
Thank you
lienot

U can do it manualy yeah .
If its easier for u why not. Just fix permissions and thats it.

Beacouse TWRP newboot.img image breaks call sound flashback stock boot image after flashing (will bring back white twrp)
but your call sound will work.
STOCK boot.img

UPDATE 2
After a few tests, when you flash back to stock recovery, flash back TWRP S6 EDGE (not zeroltetmo.img) recovery.
twrp-2.8.6.0-zeroflte.img is correct one.
Now you will have working TWRP and call sound without white screen.

Just an FYI, I did as above, and ended up with a black screen in recovery after flashing twrp-2.8.6.0-zeroflte.img
I had to flash stock firmware in Odin, which then failed. However a quick flash of CF Auto Root again, and phone booted as normal.

Current modification changes the 32 to 37. It's pretty darn loud for me and I might reduce it .
You can consider changing it to your liking and copy the xml into \system\etc. But honestly, I'm not sure how large this value is allowed.
Thanks kajkac for the mod!
More people might consider copying the XML instead of TWRP since PingPong root is becoming widespread :good:

Yes xml copy is also fine, i tested with 37 and is loud for me, but with value of 39 or 40 sound became cracling especialy vith viper sound but is damm loud, i will atach xml file in post also.

I should probably mention that at least on the SM-T710, this seems to interfere with the onboard mic, limiting me to using a headset. Restoring the original files fixed it though.

Wished there was an undo package but luckily I had a backup. Volume is increased, but increased to the point of crackling and distortion, and all it takes is a louder than average video clip or music sequence to do permanent damage. I used to edit max volume on my Nexus 5 that had KitKat and editing adiofiles were more straigforward. On Marshmallow I dont know where to begin on what to edit.

I have the t719. I can give you the mixer paths files for Nougat Stock Rom and Lineage OS 15.1.
The Nougat Stock Rom has 16 mixer paths files and the Lineage OS has only one file (mixer_paths_wcd9330.xml)
In any case, the mic won't properly work on Lineage for some reason. I haven't figured out why yet.

I would like to modify the dual speaker feature for the G7 for help

When I try to modify the mixer_paths_tavil.xml file, I find that I can't understand the statement definition. I can't find the statement comment about the content of the lg mixer_paths_tavil.xml file through the search engine. Can anyone help me. Thank you very much

No you can't find it in magisk manager downloads, just download the zip, and flash it under the modules section.

I have taken a look at this module. If my understanding is correct, it tries to replace the default mixer_paths_tavil.xml with another xml file with the modifications that, I guess, should enable the dual speaker feature
I have checked that the reason why it does not work for me, is that after installing the module by means of Magisk Manager and the reboot, the mixer_paths_tavil.xml file is still the original. It has not been replaced by the one contained in the module
However, the path is well defined inside the module (mixer_paths_tavil.xml is contained in folder system/vendor/etc)
Actually, I'm experiencing a similar problem trying to modify directly the mixer_paths_tavil.xml, as described here https://forum.xda-developers.com/lg-g7-thinq/themes/changes-to-mixerpathstavil-xml-lost-t4035345
This is happening to me on Pie
So I wanted to ask you, which Android version are you running that it works for you? are you on Pie?
Thanks

Works for me on Oreo, along with Ainur Sauron, Audio modification library, Audio compatibility patch, Viper 2.7.1. Also, there's a working Dolby Atmos downloadable through Aptoide.... doesn't even need root, just a quick apk install. Make sure you're covering the bottom speaker completely and put your ear to the top speaker. It's not going to be mind blowing regarding volume. It's likely because there's no way to turn the values high enough to complete with the bottom speaker without doing damage.
