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:

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.

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:

    Yeah, the metadata doesn't work because it can't find the file that was extracted. You could add an assert for that, so if the users device uses the old HAL the script would abort.
    For some reason the file doesn't get extracted on my phone, but RR apparently uses the old audio HAL anyways, but I'm pretty sure those problems are rom specific. So the zip works :good:

    Yes, correct. V3 and v3.1/3.2 are based on jdc team's aosp rom and should work on their cm and slim rom.
    I'll look into that abort thingy, it should abort also when I flash it on my op2, just not tested it. It would be cool to have one universal version with the new audio hal and the old method. If it detects the old file it should extract v2.x and if not extract v3.x

    Shouldn't be difficult to do since this new script is a bit more clean in terms of extracting

    Mono

    ---------- Post added at 08:46 PM ---------- Previous post was at 08:43 PM ----------

    Sorry for reviving this thread in late 2018, but just wanted to give some info to other users who are just discovering this mod. I am using RR 6.2.0 (Android 8.1) and will switch to Pie once RIL is fixed. I have tried and tested v2.1 and 3.1, and they both work just fine, even with V4A. I recommend 3.1 because it has more balance between earpiece and rear speaker so more sound is being fired directly at you. Also this is not stereo, if you go on Youtube and play a stereo sound tester you hear the same sound from both speakers, but this mod still helps the sound quality and balance a lot.
