Surround Sound/True Stereo MOD for the LG G2

TO INSTALL THIS MOD ON LOLLIPOP: USE THE MANUAL INSTALLATION METHOD! THE APP IS ONLY FOR KITKAT.

This MOD requires ROOT

What is this?
This is an app that allows the phone to use the earpiece in combination with the loudspeaker to play sounds and music, thus resulting in a true stereo-like effect. The app has a set of modified mixer-paths.xml files which are used to enable the true stereo mod and gives you he option to choose between clockwise (cw) rotation and counter-clockwise (ccw) rotation of the device, depending on how you normally rotate your device.

Is it safe?
Yes, but make a backup before starting. I've been thoroughly testing it on my LG G2 running OptimusG3 1.4.1 and CloudyG3 2.1, Pardus HD Sensation Black and Stock. I tuned the sound to what I think the earpiece can handle without getting damaged. The earpiece is very clear and produces wonderful sound, but it's not that loud at all.
Other members of this fantastic community have tested the MOD on LiquidSmooth 4.0 (Lollipop) and on Stock LG firmware and reported that it works flawlessly! So yes, at this stage, it is safe to say that is

Installation instructions
1. MAKE A NANDROID BACKUP - or make sure you know how to get your device back to a working state in case it gets stuck in a boot loop!
2. Install the Mixer App and grant it root permissions.
3. You will be greeted by the following interface:

Choose whether you want CW or CCW rotation. If you normally rotate your device to the left (so that the earpiece is on your left side), choose CCW. NOTE: For CloudyG3 Users you choose the opposite of this.
If you normally rotate your device to the right, so that the earpiece is on your right, choose CW. (CCW for CloudyG3 users!)
3. Press enable Stereo and reboot your device.
General piece of recommendation - Use this mod in conjunction with dorimanx kernel, as dorimanx kernel allows you to tune the loudspeaker volume easily using STweaks. You may need to turn down the volume quite a bit (-11 in STweaks makes the sound very balanced) to avoid the loudspeaker overruling the earpiece. But then you'll really notice power of this mod, cf. this picture:

Test the mod
To test if this works see: Left/Right Stereo Audio/Visual Test.: http://youtu.be/dvqbq_0jZ_U

I don't like this, what do I do?
Open the Mixer App again and tap the "Disable" Button. Reboot and you're good to go!

Alternative installation method

1. MAKE A NANDROID BACKUP - PLEASE! Please make a nandroid so you can restore your phone in case it goes sour! I may be able to provide a flashable zip in the future, but till then, make a nandroid!
2. Copy your current mixer_paths.xml from /system/etc to somewhere safe then download mixer_paths.xml.
3. Move it to /system/etc and give it 644 permissions. 644 permissions looks like this:
xxo
xoo
xoo
4. Reboot and enjoy surround sound.

If you use dorimanx kernel and tweak the loudspeaker volume to - 10, you will get an idea of how loud it gets =)
It can't get as loud as the loudspeaker but it's definitely loud enough for every day usage.

Currently on CM12 with Render Kernel and using Mixer14.apk, and it is not working. Both CW and CCW is not producing sound in the earpiece and the loudspeaker is as normal.

Before there was the mixer app, there was the mixer-paths.XML which we used to replace the one in /system/etc/ . During that time, media playing works perfectly with stereo, but during phone calls, the earpiece is set on a permanent high volume and cannot be set down, so it was impossible to put the phone to the ear.

Thank you for reporting this. Which device model do you have?

 

[nismology]

Amazing job guys. Will be donating as soon as I can recover from Christmas.

 

[60nine]

so this will be the main thread for this mod from now on?
if yes - please ask mods to lock the other one in "themes & apps" to avoid confusion...

hny all

 

[buski]

Would it be possible to adjust volume without stweaks ?for stock kernel

Yup, I think sreeprajay is on it

Not in it's current state. I'm still trying to figure out how to modify the volumes from an app easily and in real time (like with dorimanx kernel), but we'll see.

Oh. Yes. D802.

I would love it if you could send me your original mixer-paths.xml for me to look at it, please.

Happy new year.
