[MOD]Volume Boost v1.3 (Headphone & Speaker! Easy Install! No Distortion!)

iXNyNe · Apr 1, 2014

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!

DOWNLOAD
Recommended Headphone Pack: 6520
If that's too loud you can try the 6218

Additional volume options here thanks to @willi_3609

Use at your own risk!
And please give feedback.

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:

Great sound but i think that you have to make the bass a little lower..

To reduce bass try the distortion fix thread by @darkobas in the op.

Make sure your download is correct. I checked my original local copy and compared to one I downloaded from the XDA thread and they matched exactly according to an md5 check.

All I see inside the folder is the META-INF file...

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.

Thanks. I feel like an idiot. Trying it out now

iXNyNe · Apr 4, 2014

Also, it looks like XDA didn't correctly display the code I tried to post. Anyway you can look inside the META-INF folder and see the updater-binary

Click to expand...

Click to collapse

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.

Nope I don't think I can do Bluetooth volume with the mixer file

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!
