True Stereo
For Samsung Galaxy S4

I use this mod for a while now and I think that people aren't familiar with this mod on the S4.
This mod enables the front facing speaker to create true stereo.
It applies when:
You play sound from the speakers
You are calling in speaker mode

I am not responsible of any broken speakers, use it at your own risk. Please do not use a sound increaser when you use this mod

Supported devices (It should work on all S4 devices which use the "snd_soc_msm_2x_Fusion3" file, please post if it works on your device):
Galaxy S4 GT-I9295 Active
Galaxy S4 GT-I9505 International
Galaxy S4 GT-I9515 Value Edition
Galaxy S4 SCH-i545 Verzion
Galaxy S4 SCH-R970 U.S. Cellular
Galaxy S4 SGH-M919 T-MOBILE
Galaxy S4 SPH-L720 Sprint

FAQ:
Q: How do I know if this mod will work and not break my audio?
A: Check which version you have to use, v1/v2 for old audio HAL, v3 for new audio HAL.

Q: Is this mod compatible with ...?
A v1/v2: If the mod doesn't edit/replace the file "snd_soc_msm_2x_Fusion3", it should work fine.
A v3: If the mod doesn't edit/replace the file "Mixer_Paths.xml", it should work fine.
(Viper4Android, Dolby Atmos and Maxx Audio all work fine)

Changelog

11-06-2017:
-Removed mirror for drive cleanup. The downloads are still available here on XDA.

13-08-2016:
-Updated updater script for v3.2, now it can backup the original file. To delete the mod use remover v2.2. The remover v2.2 does not work on any other version of this mod.

04-08-2016:
-Updated updater script

30-07-2016:
-Updated mixer_paths.xml file with the JDC Team AOSP rom build 26-07-2016
-If version 3.0 breaks audio in call, try this version

03-07-2016:
-V3.0 Released: Use this version only if the rom that you use uses the new audio HAL.
It sounds very balanced!
Ps: up your alarm volume since the rear speaker has lower volume to make it even with the front speaker.

03-04-2016:
-V2.1 Released: Front speaker sound lowered at low volume, still needs tweaking in low and higher volume, I should probably add more steps if possible.

20-03-2016:
-V2.0 Released: Sound should be more balanced in the volume steps, probably need some tweaking here and there. (I have not fully tested this, so do not put the volume too high!)

11-10-2015:
-Added remover
-Added new versions
-Renamed versions (True Stereo Front-Back)

17-05-2015:
-Initial release

Line number 2123: Front speaker

Line number 2122 & 2123: Front speaker
Line number 2124 & 2135: Back speaker

Version 3:

Version 3.1:
Line number 366: Front speaker
Line number 367: Back speaker

Extra:
Edit the file named "updater-script" with notepad and change the text in the quotation marks in ui_print("");, you can add more lines by adding more ui_print("");

Works on my SGH-M919 T-MOBILE S4. I am running Blisspop Android 5.1.1 CM build of October 9th 2015. Works PERFECTLY. There are NO BUGS. SPEAKERS STILL WORK IN A CALL. SOMEHOW WORKS WITH VIPER4ANDROID. I would throw my money at you but I am a poor man XD.

V4A doesn't touch the file that is edited by this mod, because not every device has this file.

Is the front speaker even made to go this loud? I'd be afraid of blowing the speaker.

It can handle it without cracking noises. If you go over 75% at the config, you risk damaging it, do not use any sound booster mods which increase the sound by a lot, a little boost is no problem.

How do I change between the Front and the Back Speaker? I flashed the Medium-High File and the Back audio is louder now but I cant hear the front speaker.

There are different versions for the volume you play. If you use higher volume, the front speaker should be high and the back low.

I can not perfect the sound balance as it isn't made for that

It also works on Galaxy S4 Value Edition I9515 with CM12.1.
But it is not true stereo because there is no left and right channel for sound.
It just plays one channel over 2 speakers or does the Youtube app only support mono playback?
But I still like this mod.
:good:
