Hi there,
I was installing Viper4Android on my GT-I9505 and came across this error about the LPA (low power audio). I then clicked ok but nothing really happened. My Viper then didn't work on the settings I wanted them to so I had look and fixed it here's how:
1. Download a build.prop editor from the play store e.g.(JRummy's BuildProp Editor)
2. Go/Serch for this line: Ipa.decode and lpa.use-stagefright
3. Change them to false.
4. Reinstall your drivers
5. DONE. ENJOYYY
Tested on i9500/i9505/i9505i/i9506
Please hit the thanks button if I helped

USE WITH CAUTION!
I not fully tested yet...so do a NANDROID Backup before modding anything!
1) GUIDE for Manual Installation
-Download Files Pack: HERE
-Extract files on phone and put they in the various directory like in the .rar:
Code:
[B]/system/...[/B]
-Open /system/build.prop with a text editor (like RootExplorer)
and add these lines at the end:
Code:
#Additional Tweaks by XxXPachaXxX
#Xloud Engine Service
nro.semc.sound_effects_enabled=true
nro.semc.xloud.supported=true
npersist.service.xloud.enable=1
-Then, Save the file and Exit
-Now, set the right permissions or open a terminal emulator and execute:
Code:
su
busybox chmod 0771 /system/framework/semc_audioeffectif.jar
busybox chown 1000.1000 /system/framework/semc_audioeffectif.jar
-Fully Reboot the device and enjoy
How To ROLLBACK to stock:
- DELETE ALL files, LISTED in FilePack.rar
- Erase lines for xLoud in Build.prop
- Put libaudioeffect_jni.so from your ROM to /system/lib/ (set permissions rw-r--r--)
- Full Reboot

Youve missed the 1 at the end of enable= on the last line
I will have a try
thx
Does this work on AOSP ROMs?
giving it a try .. will give my verdict later
In build.prop i see required string, and sound seems much louder, but no quality...Any chance make Beats Profile for all sounds on device??
Apparently it screws your speakers....

Please read the thread!, IT DAMAGES YOUR SPEAKERS I think this should be closed, unless someone improves it and stops it from damaging the speakers
My volume with CM 7.1 is unbelievably low. I can't imagine this Audio Hack could damage my speakers even if it tripled the volume of the speakers (that would just probably take it back to the volume levels I had with Sense).
i installed it and it makes it a lot louder and i think it will kill the speakers
the only why to go back is Nandroid backup?

unfortunately yes !
To get back:
- DELETE ALL files, LISTED in FilePack.rar
- Erase lines for xLoud in Build.prop
- Put libaudioeffect_jni.so from your ROM to /system/lib/ (set permissions rw-r--r--)
- Full Reboot
Already done on ARHD using Root Explorer. Stock sound returned

Hey guys above is the Google drive link for official ota update for our Lenovo a6000 plus 1024mb
I had rooted Lenovo a6000 plus to install the viper4android fx equalizer did not install any custom rom
Rooted using superuser app using adb and successfully unrooted using the native superuser full unroot option. Still I was scared that the ota might brick my phone, but no it didn't brick my phone. I heard people bricked their phones using the kingroot app.
Place the zip file into sdcard0/lenovoota/
And press on the new found firmware and click update now
If this method doesn't work do it manually
Goto about/software updates
1. Click on the leftmost capacitive button
2. Click on toolkit
3.Then click on the first option install update from sdcard by a zip file
4. It will reboot the phone into recovery and ask you to select the zip file
*In the recovery Use Vol up and down to navigate ; Power button to select*
5. select the zip file and then select yes
6. sit back and relax ,wait for 10 to 15 mins
7. After update it is recommended that you apply a factory reset.

My review:
https://youtu.be/EVMmETp1_Ec
Changes:
1. Camera is very well caliberated and optimized to capture good images makes the camera more optimized with less grains and no over exposure of flash
kitkat vs lolipop camera samples: http://snappydevelopers.blogspot.in/2015/09/lenovo-a6000-plus-kitkat-vs-lolipop.html
2. Battery saver which can boost your battery upto 90 mins more
3. Material design
4. 3d multitasking tray which is always helpful.
5. lockscreen notifications and float notifications and caller float notification
Bugs solved after a factory reset:
1. WhatsApp contacts not displayed
2. play store 64 bit error
Bugs: https://youtu.be/QHvGJkyblfo
1. Third party apps cannot write to the external sdcard
*The default apps can write to external sdcard*
2. default launcher pops up after every reboot
3. after unplugging the headphones the ringer volume is turned low
4. The mx player when headphones plugged in and volume increased above 10% it quits the app.
5. All four cores are running continuously which drains the battery faster but the phone still can manage to give a backup of 1 days on moderate-heavy usage and 1.5 days on low-moderate usage
6. No multiuser support
7. Estimated charging time not displayed on the lockscreen
8.One more bug which I noticed recently is that some facebook videos won't run
Hope Lenovo will fix these bugs soon

[Solution] To fix Bug 4 ( MX Player Closing automatically at sound level above 10)
Just found a simple solution to fix Bug 4...
Go to the Settings of MX Player -> Audio and make sure System Volume is unchecked...
Hope this helps..
You can then increase the system volume as much as you want with the volume buttons on the right side of your phone...
I take no credit for this amazing equalizer. All credits go to @zhuhang and the people from his thread for the convolvers.
If you don't know what V4A is check here for more details.
But basically it's an audiophiles dream that can cause serious hearing loss and such audio enjoyment at the same time!
The Zip has all the files included to enable "neon" support for convolvers, which are also included.
The feedback I've received so far is 100% success.
INSTRUCTIONS:
1) DOWNLOAD THE ZIP
2) FLASH IN RECOVERY (no need to uninstall if you already have viper installed)
3) open the app and you will be prompted to install the drivers. (I always choose the top one, although it does consume more batter, we'll worth it)
The EQ can be either super simple with just the basic adjustments or can get really technical in "expert" mode.
To activate the convolvers hit the 3 dots in the top right and click click the "ui settings" and change it to expert
Current version Download and discussion starts here
UPDATE VERSION 2.4.0.1 Neon Enabled + Convolvers
If using my previous zip version a simple flash of the new zip will update your V4A.
If you are running any version other than the one in my previous zip you will need to follow the steps below to ensure a smooth update to 2.4.0.1.
1) uninstall current driver from Viper by selecting the option is the app or use file manager and delete "libv4a_fx_ics.so" from system/lib/soundfx.
2) wipe data app with application manager or TiBackup
3) uninstall your current V4A
4) Flash to new zip
5) boot up and enjoy
6) hit the thanks button.
old version
Viper4Android neon enabled including convolvers
Thanks to @SammyTRK for confirming it works for this device!
Enjoy!
With permissive enabled kernel, just install v4a as normal app, neon also enable.

I don't know if i will update this, installation instructions may change over time, make sure you contact/read Viper4Androids instructions before hand always. Especially if this topic gets dated.
__________________________________________________________________________________________________
FAQ:
Question: Why not use the Playstore version?
Answer: It's not officially maintained by the Viper4Android devs, this is easy and secure and up to date.
Question: Why do i need the SELinux Changer application?
Answer: Our firmware comes with SELinux mode ENFORCING, which does not allow Viper4Android the permissions it needs to install properly and installation without this will result in only the Viper4Android app working and making no changes to the sound quality as the sound driver fails to work. What this app does is change the mode to PERMISSIVE, which gives it the permissions to install properly so the sound driver installs successfully.
Question: Can i uninstall SELinux Changer application after installation?
Answer: No, the sound driver will fail as soon as you remove it, as it goes back to ENFORCING mode.
Question: I followed the instructions but i still did not notice any sound improvements?
Answer: Try rebooting and wait a couple minutes then open SELinux Changer and make sure it has root access and select PERMISSIVE and make sure It's on by closing and opening it and reboot and try again
*Reinstall the sound driver
*Make sure you tick Enable Viper4Android in all the tabs if you don't know which one your audio is played through and just to be sure
*Post in the Viper4android thread
Question: Can i install this as a user app? And is this a system app?
Answer: Yes you can install it as a user app but you might have problems with installation. Yes this is a system app.

Did you follow the instructions correctly? I think you did not follow the SELinux changer part.

I followed it all. Btw, i got unlocked bootloader and I used eagleroottool to root my device
Edit: It says "Driver installation failed, the busybox found on your device doesn't work. this usually means you installed the wrong or broken busybox, V4A needs stericson busybox to work. If you are sure about having installed the proper busybox, then please confirm your device has been properly rooted."

Already did but still not working. I'll try it again later
Edit: Got it to work. I used solid file explorer rather than es file explorer. Thank you
I would like to share to you a sound setup that would improve the sound quality of your device to your preferences. This is a bunch of guides I searched in XDA forums and tested them with my PAC-ROM KK RC-3 setup. Though it is a software-level modification, I found the end result quite pleasing.
Disclaimer:
I am not responsible for any damage that this may cause you. As a golden rule, make sure you to run a full backup of your current setup in case something goes wrong with the process. I have only tested this in my device (model: S7562). Do follow the instructions extensively.
Pre-requisite:
~An android 4.4.4 Custom ROM
~Latest TWRP custom recovery built
~With root and Busybox installed
Instructions:
1.) Download and flash the 4.4.x Viper4android driver found here.
2.) Run this current Viper4android app. That should prompt a driver installation dialog box. Proceed installing it and choose what ever mode.
3.) Download and install the latest Viper4android apk. (currently using 2.5.0.5).
4.) Run this latest Viper4android app in order to update the driver to the latest.
5.) You can now disable the old Viper4android app (the one with the violet icon).
6.) Setup the Viper4android the way you like it, and also use a music player that integrates an equalizer (like Phonography or Spotify) and your good to go.
Current headset profile (got it from this):
Master power - on
Playback gain control - off
FET compressor - off
Viper DDC - on, set to sennheiser hd558
Spectrum extension - on, set to 1.0
Firequalizer - off
Convolver - on, set to Samsung soundalive tubeamp(included in the IRS samples)
Differential surround, field surround, headphone surround+, reverberation - all set to off
Dynamic system - off
Viper bass - off
Viper clarity - off
Tube sound simulator - off
AnalogX - on, set to extreme
Rest all are turned off or kept the default.
