Download ExperienceOS Add-on Aroma 5.0 and flash Divine Beats Audio mod here: https://forum.xda-developers.com/oneplus-5/development/rom-experienceos-r1-0-lite-addon-t3626657

Simpliest way :
- Download and install Busybox on your phone.
- Set SELINUX to permissive mode.
- Download and flash this Viper4android Zip : www.androidfilehost.com/?fid=745425885120697254
Normally all should be working. (Maybe open Viper4android app and install the driver first)
Also don't forget tout uninstall or disable any other audiofx you have.
(I know it's still the 2.4.0.1 version but it's still my fav)

Does this work while encrypted? Also does it require any additional file tweaking or driver installation?

Works like a charm! ?
Thank you so much.
Cheers

It is working for me only if I set SELinux to permissive. Tried so many diffirent builds. The last one is ViPER4Android_2.5.0.5_guitardedhero.zip.
(used the guide from here: http://andxda.blogspot.com/2016/09/how-to-install-viper4android-on-android.html)
Did someone have a success to run viper4android in selinux Enforcing mode !?

I have no idea about the SELinux modes but I just flashed the Deutronomy zip without changing anything else and now it works perfectly

What ROM are you using ? OxygenOS 4.5.8 ?

I am running OxygenOS 4.5.8. Root and BusyBox is installed. I flashed this zip but still get:

The same second I change SULinux to permissive - all start working fine....

Another Method
Hey Guys,
so I found another way to get V4A working.
Worked for me on enforcing too, but i couldn't test it 100% because my ROM is permissive.
This Viper version is called Viper FX and has the same features as V4A by guitardedhero.
It is a Magisk module so u need to be rooted with Magisk to get this working.
ViperFX:
https://forum.xda-developers.com/apps/magisk/viperfx-mkm-magisk-t3535401
I also found another very usefull Module called Universal deep_buffer remover.
This Module allows you to use Viper FX with streaming apps (e.g. Soundcloud, Pandora, ...) which are normally not affected by Viper.

Tried the version in Magisk repo, but nothing happend after reboot. I can see the module in magisk but no Viper4Android-app. So I did a delete in Magisk Manager. Also, the thread is closed now.
Going to try install V4A via TWRP and his new module.
https://forum.xda-developers.com/apps/magisk/alienoidos-t3660485
Update:
Didn't work for me. No V4A-app, so I installed it manually and it tolds me to install drivers, did that reboot and it still said install drivers.
I'm on latest OOS with Magisk 13.3

I have a OnePlus 5, so you guys ought to be in good shape. The zip attached below is intended to work perfectly for Magisk and SuperSU users in Enforcing SELinux Mode.
In fact, if genuine init.d support is obtained (I've been trying for weeks now...), no root will be necessary at all.
BusyBox is already unnecessary for any installation scenario, though. Of course, I mean unnecessary for ViPER4Android. BusyBox has its uses elsewhere in Android. :good:

You're not alone.
ViPER4Arise is merely a themed version of ViPER4Android and ViperFX designed for the ARISE Sound Systems™ project.
ViperFX is merely the current 2.5.0.5 version of what is known previously as ViPER4Android, although it hasn't quite caught on obviously. This slight name change was a part of much bigger and impactful changes such as the official website address/domain, for example. :good:

Lol yeah, that is certainly not the intended outcome. At least we now know it is something on your end, most likely Magisk-related, although an existing v4a data or system installation can produce those same results.
I recommend a factory-reset in TWRP followed by an OOS-4.5.8 flash whenever it feels like a good time to do so, or at least uninstall and reinstall Magisk if nothing else.
We'll get you going, don't you worry. :good:

[GUIDE] Ultimate audio and battery guide

Comprehensive audio guide for android 8.1 and P DP1 (saves battery)
Cyan means 8.1 ONLY​For android P only, flash the magisk modules in TWRP, manager is broken with module flashing, just a temp patch from @topjohnwu​
I am not responsible if you break, blow up, or destroy your device in any way​
Hi XDA, this is the comprehensive guide to making the google pixel and XL have the ultimate audio mods installed while saving battery (if xposed is what you're looking for, it's under amplify)
Prerequisites
TWRP 3.2.1-x
Magisk v15.x REQUIRED

As far as I believe Arise doesn't work with 8.1 (could be wrong) But I use a magisk Module Viper4Magisk or whatever it's called will install V4A works fine I tried a Dolby Oreo zip on the Arise thread but it didn't show in app drawer so not sure if that installed correctly hope that helps :good:

Fwiw, I used this with Magisk 15.2 in a clean install of 8.1. Working without issue

It doesn't actually give you dual speakers though? My understanding is that one side is a speaker and the other is a microphone.

First of all are you on aml viper? ARISE doesn't work with 8.1 and i'm talking to some of the devs about fixing this issue. I've had some experience with LOS, it may be throwing an error because of the rom or because there are some other things LOS has by default that is interfering with viper. The builds are unstable, my advice would be to switch to crDroid because it is LOS based, but is made for audio. I'm not sure what you mean by prompts but I have been hitting the vol up key both times and it works for me on the Pixel Dust rom

I changed the v4a guide, you don't need the permissive module, maybe that's what's crashing it?

It didn't "crash" per se, it just wouldn't install the necessary driver after the package was installed. I'll try it with the module disabled and see if it works. Do I still need the permissive module for the other mods? Or just when they're being installed?

Viper4Android on the Redmi Note 7

Hello there, I've been trying to get the viper4android but it just keep asking me to install the driver.
I've tried with the magisk module and the xda labs version (which looks awesome btw).
I'm on magisk 19.0
My rom is xiaomi.eu 10.4
Any ideas?

Just install a Magisk module or a script to set SeLinux as Permissive. I am using it right now and everything works great.

I've had trouble installing it, too. Tried every rom posted on this forum, stock MIUI, and some GSI, and in none of them I could get V4A working. Used Magisk Module, too.
Could you please ellaborate how you installed it? Which rom? Which Magisk/V4A version?
Viper is literally the only thing I'm missing from my previous phone; I'd reeeally like to enjoy it again!

Yes, I tried that one as well. Always the same error: "No driver installed", press yes, restart phone, and back to "no driver installed" again.
Which busybox version are you using?

Ok, I finally got it.
I'll write it here for anyone with the same problem, or for future reference.
First, check that you have BusyBox installed.
Then, in Magisk Manager, install the Audio Modification Library. Reboot.
In Magisk Manager again, install the Viper4Android module. Install options: new driver, old interface, user app, library workaround no, oneplus 3 workaround yes. Reboot.
Check opening the app, it should work normally, with no "driver not found" errors.
Notes: tried with letsmakecake's Lineage 16. People in the RN7 Telegram group recommend busybox.zip, but I confirm that the stericson app works the same.
If anyone has problems making it work with Poweramp: settings->audio->advanced->
- Direct Volume Control: disabled
- MusicFX: enabled
Then go to the eq screen, second tab, press MusicFX so it's enabled.
Thanks all who helped, and the V4A devs. This is the best audio tweak mod available for Android, hands down.
Personal recommendation: try the Dolby Pro Logic II irs in the convolver!

Alright, can confirm this works, with some minor differences:
-new interface (just personal preference)
-library workaround was applied automatically
I also have selinux permissive and MusicFX disabled (app frozen).
The package I used is Viper4Android FX Legacy. The new version, Viper4Android 2.7, did not work for me.
My ROM is HavocOS.

Viper4Android On Stock 8.0 Rom

Hi guys!
This is my first thread so sorry if i make any mistakes, so let me know if i did any!
So as the title says, We can get viper4android on stock rom but we need to
-Have unlocked bootloader
-Magisk
-Big brain, and focus to not f. it up!
-Back up your rom and data, just in case :silly:
So, we need magisk to install Viper4android module
-Magisk: https://github.com/topjohnwu/Magisk/releases/download/v20.4/Magisk-v20.4.zip
-Viper4Android magisk module:
https://zackptg5.com/downloads/v4afx_v2.7.1.6.zip
-App Uninstaller:
https://redirect.viglink.com/?key=e...uninstaller-remove-package-t3423910/amp/&ref=
So first we need to install app uninstaller and give it root and memory premissions, after that we need to find any app that is associated with miusic enchacments, like in my case: MiusicFX and Sound settings/Enchacments, And uninstall them!
After it uninstalls we refuse to automaticly reboot, then we launch magisk and install viper4android module either from Modules sections and selecting Viper4Android file or just searching it in Download section
After it downloads and installs we, again not reboot and just launch the viper4android app, give it root premisions after we click to accept the messange that tells us that it will intall an driver for itself let it istall.
After the viper installs itself phone will reboot automaticly.
Viper can not work on first boot, like in my case just open the app if it not works reboot the phone and it should work fine.
And Viola, You have Viper4Android on your stock Sony rom :laugh:
If you have any problems let me know. I will try to help you :silly:

Viper4Android (2.5.0.5) works like a charm. I have installed it on VNS and RNE model without any problem. I only have problem to find IRS files for my headphones, but i can live without that .
Btw, some files can be found
HERE
Requirements:
- Root
- BusyBox (the simple free version is enough) installed
- EliteKernel installed (due to switching selinux to "permissive")
- Solid Explorer apk installed
- TWRP
- Selinux Switch Apk or Kernel Adiutor apk installed
I used this guide to install:
https://www.gizdev.com/dolby-atmos-and-viper4android-on-emui-5-0/
Note: by installing Elite Kernel you also get OTG function. If you want to use it, use SuperSu to root, not Magisk. With Magisk OTG will not work reliably, probably not at all...
If you want quality sound, use Onkyo HF Player .

Note: by installing Elite Kernel you also get OTG function. If you want to use it, use SuperSu to root, not Magisk. With Magisk OTG will not work reliably, probably not at all...
If you want quality sound, use Onkyo HF Player .
