Hello there,
I already searched but found nothing at all.
Is there any sound mod compatible with stock Lollipop (LRX21P)?
I tried an universal DSPmanager zip found on the N5 forum and the lollipop version of Viper4Android (also found on N5 forums), but with no results (quality/volume/effects don't change with options on/off). I can confirm that they don't work.
Thank you very much for your help, it would be very appreciated (the earphones I bought are too bass oriented and listening music is awful!).
I'm updating this thread because I solved my question. Viper4Android is now working on my stock Lollipop rom (on Flo).
Steps (root and custom recovery needed, update to last version of SuperSU)
1) Download the file linked below (V4A Lollipop "beta" version, taken from N5 thread) - the zip removes MusicFX and DSP if you have them (lucky you, because I hadn't)
http://forum.xda-developers.com/attachment.php?attachmentid=3018995&d=1416178083
2) Change kernel to Permissive using SELinuxModeChanges app from Play Store
3) Install Busybox if you don't have it already
3) Go to developer settings, UNCHECK "Use NuPlayer"
4) Reboot to recovery and flash the V4A file
5) Clear cache
6) Reboot, open the V4A app, install drivers (from up-right menu), then reboot again
7) Set the V4A settings the way you like them*
8) Profit! Disable specific-app EQs in the single apps, and use V4A EQ instead.
Sound is waaaaay waaaaaay better now. Can calibrate sound on my earphones, finally.
Thanks for posting your fix! Gonna give it a try now.
Awesome! Just what I was waiting for. I been looking all over but apparently missed this one. I am going to try this now.
Pffffff Viper4android working again on my N7 lollipop . Very important, thanks for this info.
Now the question is: is it bad / harmful to use my Nexus 7 with the kernel in Permissive mode?
Verstuurd van mijn Nexus 7
but are your IRS convolver files working? because it isn't for me.

3. Download latest viper4android (v2.3.4.0) from - <http://forum.xda-developers.com/showthread.php?t=2191223>
4. Install SELinuxModeChanger & change the Mode to "Permissive".
5. Now install viper4android.
6. Open viper4android app:
a. Install driver
b. Select "FX Compatible Mode" --> Compatible
7. Reboot.
I have tested this & it is working perfectly fine on Blisspop ROM (11/02/2015 build) !

Hello Guys!
As you know, lots of people root their phones only for Viper4Android. It Increases the audio output of your phone x5 times*
So What You'll Need.
1. BusyBox
2. Latest Version Of BusyBox By stericson
3. Latest Viper4Android Version.
4. Motion Based Roms
--- Disclaimer ---
Me Neither XDA take responsibilty for what you do to your phone. It is you who are modifying the files and you take all the responsibilty. Don't ask me for help if you mess things up. Please take a Nandroid backup before you proceed. Please read the whole guide for full results
--- STEPS ---
•Install BusyBox by stericson from playstore.
•Install BusyBox on your phone
•After BusyBox installation, Launch Viper4Android and install the driver
•Re-Boot your phone
•After Re-Booting, launch Viper4Android and you will get an error message! Don't worry tho, you will not face any problems. Close Viper4Android
•After Closing, open Build.Prop with your root browser or any other browser with editing capabilities.
•Find This Line and replace-
lpa.use-stagefright=true
To
lpa.use-stagefright=false
•Save the file
•Then, Go to setting and application manager
•Go to the all tab
•Search SoundAlive and disable it(Nothing wont happen)
•Re-Boot Phone!
•Now play any song and see if the driver is processing the audio.
(TO SEE IF IT'S PROCESSING, OPEN VIPER4ANDROID AND TAP THE 3 DOTS ON TOP RIGHT CORNER, TAP ON DRIVER STATUS AND CHECK . )
--- THAT'S IT ---
Now you can tune the setting of viper4android to your heart's content.
--------------------
For Advanced Users -
Tap on 3 dots and selct UI Settings, select your option and go on...:laugh:
TESTED ON : GT-I9300I, Running Project Lucky V1.1 ROM, Android 5.1.1
Guide By - SnapDrag910
Bugs - Driver Restarts itself while playing audio. It takes a second for it to switch off and restart.
*** IT DOES NOT WORK ON CM 11 OR 12 BASED ROMS ***
Press The Thanks Button if i helped you!
I used Viper4Android on Cm 11 , 12 and 12.1 so it can work with them
for solving the bug if restarting drivers use this sound mod it's better than normal Viper
https://forum.xda-developers.com/android/software/mod-beatsaudio-e-xloud-installer-t3029951
I used it to on pl 1.1
its long procedure but worked for me I've used this one on AEX latest pie version and Bootleggers latest pie version plus nameless latest kernel on both rom Don't know about other Treble Roms I hope it will work with others too If anyone trys other tell me by posting this thread.....
I'am not developer for this mod so all development credit goes to www.opendesktop.org
But for workaround all credit goes to me
BEWARE YOU CAN'T UNINSTALL IT YOU HAVE TO DIRTY FLASH YOUR CURRENT ROM AGAIN TO UNINSTALL IT
- First delete both audio_effects.conf file from both directories (/vendor/etc/) and (/system/etc/)
- Set SELinux to Premissive use (https://forum.xda-developers.com/apps/magisk/selinux-mode-inverter-t3775271)
- Flash ClearSound Mod (https://za.gl/gsSDdb)
- Flash Viper4Arise (It will take upto 15 minutes don't be panic till that time)
https://www.opendesktop.org/dl?file...s.zip&file_size=128218850/&project_id=1274328
Note : use aroma installer then in installer screen, select materialize version and yes to (lib workarounds)
- Reboot
- Open DD4Arise App click on power icon to enable sound effects
- Open Viper4Arise App and install driver and Reboot
------------------------------------------------------------------------------------------------------------------
If it Doesn't work like what happen in my case DD4Arise force closes and Viper4Arise driver install loop again and again so I've found an workaround :
- Open (/vendor/etc/audio_effects.conf) and find (libv4a_fx_ics.so)
- Change path to (/system/lib/soundfx/libv4a_fx_ics.so)
- Open Viper4Arise and install driver and Reboot
------------------------------------------------------------------------------------------------------------------
If still issue remains then final thing :
- Open Magisk and Go to Download section and search for Dolby Digital Plus latest module and reboot
- Open Magisk and Go to Download section and search for Viper4Android latest module and reboot
Note : this one Viper4Android version have aroma installer so use volume buttons and input according to screen instruction, same as above select materialize version by pressing volume up and yes to (lib workarounds) using volume up but there is an extra option for OnePlus which you have to decline by pressing volume down
- Open Dolby app click on power icon to enable sound effects
- Open Viper4Android App it won't ask you to install driver just check driver status and enable master switch then status will change to Processing
Feel Free to Thanks me If It will work on your z2 plus
I did not get any aroma installer while installing the mod.
This mod doesn't improve sound and old and bugs default sound files, pie has already improved audio. All u need is to instal ZAP mod less than 1mb and get an good earphones ?

when you flash this :
https://www.opendesktop.org/dl?file...s.zip&file_size=128218850/&project_id=1274328
It will ask you to use aroma or traditional one and both of them have the same instruction as i've mentioned above difference, only UI is different you have to press volume up or down button to choose option in traditional installer.
Doesn't install anything !!
Found this thread on XDA for the latest Viper4Android method that also works on the Poco F3 with Root and SELinux enforcing mode.

Most of convolvers are outdated, the best you can do is to go on the viper4android telegram channel, contact Thomas de Witt and pay 4 euro for a personal convolver for your headphone. Or you can do it yourself but it requires some solide knowledge. There are too convolvers from stormviper, a modded viper4android but the creator is a little strange and you have to ask them personally and do a "review" for the creator to get the last convolvers (testing purpose I guess). They have a telegram channel too. You can still find pack on Google but it's old. Sorry for my English !

Those irs files are overrated, I personally like the same settings on all of my headphones. I like moderate gain, set to inf, I love level 3 surround sound, dynamic system high end v1 at 20 percent for bass, clarity 12db or 14.8db it depends. That's my perfect settings for Bluetooth, headphones don't require so much gain. You can also search Google fiio fh5 github or IRS file and it used to find the github for those headphones I can't seem to get it anymore. There honestly nothing special they make headphones sound worse really

Global IRC, indeed, but the creator of viper4android can create a custom one based on your specific headphone and just for your headphone. Therefore, the quality is a another world from basic irs. The one you find free today are old and so, they make more bad than any good.
I don't believe the version I'm running from the thread in link above has Surround, Headphones and Bluetooth options.

The creator of viper doesn't do anything anymore. The team Dewitt isn't the creator he's just using the open source code for the Normal driver because the viper creator won't allow him access to super quality driver from 2.3.4 my choice. No those custom IRS files are junk I have the fiio fh5 iem and the IRS files they made it makes my headphones sound wimpy. Trust me find the settings you like on viper and a good pair of headphones like my personal favorites are Master and dynamics MW08 Bluetooth.

I tried to install it but I have a I/o error, from what I read I have to change the name of a file inside vendor/etc but I can't because of permission, could you tell me how did you do that ? Thx !
I installed everything over magisk.
First Ainur Narsil and Audio modification library then reboot. After that viper then open viper and install the driver. The device will reboot. In magisk deactivate both Ainur and AML then open viper again. Driver should reinstall again. After reboot it should work. Could be that you have to enforce in settings. In a link above there is this method mentioned.

It's going to seem like a lot of work but it's not. Your just going to download magisk files. First thing first you have root and I'm hoping your willing to switch your kernel to permissive mode? You can either do that with permissive v2 magisk module or selinux app. You need to have busybox from magisk installed.
Download 2.3.4 apk
1 switch selinux to permissive
2. Install BusyBox from magisk
Than reboot first
3. Install viper4android v4.4 on magisk manager use volume buttons to pick 2.3.4 install as a user app and if show recommended audio fix hit yes.
Reboot the device and see install the apk 2.3.4 and it should have the driver already installed.
If that doesn't work than you add James dsp magisk module new verison on magisk manager
Than flash audio modification file v4.0 after that
If you reboot again and reinstall the app and hopefully the driver will stick if it doesn't flash 4.4 zip again and reboot and install the apk.
You have to always reinstall the apk because the viper zip uninstalls it and it doesn't ever add it back likes supposed to but the driver stays installed and when you install the app shouldn't be no errors. You will need to grant storage permission for viper4android app.
It seems like a lot but it's really not and once it's installed properly it never uninstalls.
James dsp allows viper to play on phones for some reason but you can turn it off and just use viper that's what I do

Nevermind, I thought I had to install Jamesdsp "verison", like a special Jamesdsp lol, everything work great right now!!! I really thank you for your time, really ! But just one last question subsiste, how I'm sure it's the super quality driver that is installed and not high quality or energy saving?

Always, much better than Dolby, AudioFX and others that I tested.
The "codecs" most important is DDC/Kernel (.vdc and .irs).
When I install them in 2019 liked ClearPlus HD.irs and V4ARISE.vdc.
It's a little hard to set up (Viper and set presets) but when you learn is easy do the same for all headphones.
Maybe it could help.
I recommend you remove that older process installation because you don't need to change SELinux from Enforcing to Permissive (insecure).
In Magisk
1. Install Audio Compatibility Patch (v2.3)
2. Options: Yes, No, Yes, No, Yes, Yes, Reset.
3. Install Audio Modification Library (v4.0), reboot.
4. Instalar Viper4Android FX Legacy v4.4 (v2.5.0.4)
5. Options: Vol +, Vol-, Vol-, Vol +, Reset.
6. Install the JamesDSP module.
7. Disable any native system / ROM equalizer.
Install Viper4Android FX app (v2.6.0.6, Jan/2019) via github or backup
Option: find out him here or Magisk folder (use any root explorer for that).
Path: /data/adb/Modules/Viper (old app)
For newest V4A app use search or Rose.
Choose driver 2.5.0.4, install, restart.
So open the player.
Open Viper4Android FX app, try to apply some profile. Close and open the app if necessary.
Your Headphone need to be plugged.
NOTE: Don't forget to disable other features sound installed on your ROM like stock equalizer (AudioFX, Dolby and other).
To work correctly the Driver Status screen must be:
Driver Version: 2.5.0.4
NEON Enable: Yes
Enable: Yes
Status: Normal
Audio Format: Supported
Processing: Yes
Sampling Rate: 48000
NOTE2: The Viper4Android folder saves the profiles in the root of the internal memory and they need to be replaced in case of Internal Storage was formatted.
I upload the files (older .apk and DDCs/Kernel) on my Mega
18.21 MB file on MEGA
mega.nz
There is some perfis that I did for my headphones (JBL, Xiaomi, Bluedio, Phillips and KZ). You can try them and use it as based to fix all what you need.
Change it to others device you will need just set "Master Gate (limiter)" to 0dB on Alioth.
All them was set for Gemini (this need to be Output Gain -8.0 db).
NOTE3: I prefer the older version and older design. Just the older design app works with the folder "Profile" on .zip without any conversion files.
The new layout migrates the folder "Profile" to "Preset" on new material design. This is not compatible.
NOTE4: Maybe just AML + FX Legacy or 2.7 + JamesDSP is enough. You can remove James app after installed his Module.

As I said, you don't need to alter SELinux permissions.
There is a method that you don't modify that.

Always, much better than Dolby, AudioFX and others that I tested.
The "codecs" most important is DDC/Kernel (.vdc and .irs).
When I install them in 2019 liked ClearPlus HD.irs and V4ARISE.vdc.
It's a little hard to set up (Viper and set presets) but when you learn is easy do the same for all headphones.
Maybe it could help.
I recommend you remove that older process installation because you don't need to change SELinux from Enforcing to Permissive (insecure).
In Magisk
1. Install Audio Compatibility Patch (v2.3)
2. Options: Yes, Up, Yes, Up, Yes, No, Reboot.
3. Install Audio Modification Library (v4.0), reboot.
4. Install Viper4Android FX v2.7.2.1 (driver v2.5.0.4)
NOTE: Viper FX will install the latest app, finish installing Driver v2.5.0.4 on it and running (do some test to confirm).
Afterwards, remove the latest app and install the v2.6.0.6 app.
Install Viper4Android FX app (v2.6.0.6, Jan/2019), required download via github or backup.
Choose driver 2.5.0.4, install, restart.
So open the player.
Open Viper4Android FX app, try to apply some profile. Close and open the app if necessary.
Your Headphone need to be plugged.
NOTE: Don't forget to disable other features sound installed on your ROM like stock equalizer (AudioFX, Dolby and other).
To work correctly the Driver Status screen must be:
Driver Version: 2.5.0.4
NEON Enable: Yes
Enable: Yes
Status: Normal
Audio Format: Supported
Processing: Yes
Sampling Rate: 48000
NOTE2: The Viper4Android folder saves the profiles in the root of the internal memory and they need to be replaced in case of Internal Storage formatting.
I upload the files (older .apk and DDCs/Kernel) on my Mega

There is some perfis that I did for my headphones (JBL, Xiaomi, Bluedio, Phillips). You can try them and use it as based to fix all what you need.
Change it to others device you will need just set "Master Gate (limiter)" to 0dB on Alioth.
All them was set for Gemini (this need to be Output Gain -8.0 db).
NOTE3: I prefer the older version and older design. Just the older design app works with the folder "Profile" on .zip. The new layout migrates the folder "Profile" to "Preset" on new material design. This is not compatible.
As I said, you don't need to alter SELinux permissions.

You can convert all profile to new format with a magisk module. But here, I'm more interested in the old version 2.3.4.0 with the super driver, discontinued in the new versions

Does't work and duplicate profiles (older profiles, if you don't migrate will works idem).
As I said, I tested both and the most stable is Driver Version: 2.5.0.4 and Viper4Android FX app v2.6.0.6.
Doing it correct, you can allow quality more than 200% compared without it.
