Some of user reported that Viper4Android is not working on Nougat based ROM.I also faced driver installing issue on RR 7.1.1 after successful flashing V4A.This is because V4A is not officially released for nougat. Look here.
So if want working V4a then :-
Use Arise sound MOD(V4A driver is preinstalled)
OR
If u want only V4A then Do a Little Google search=>Flash V4A(I have tested with v2.5.0.5).Go to /vendor/etc.Make a backup file of audio_effects.conf and delete it or rename it by audio_effects.conf.bak. Then open V4A and install driver.Wait for 3-5 sec and then reboot.
I tried installing the viper4Android on moto G5 Plus India variant and installed the driver.
I have already installed busybox and rooted with su.
But the viper4Android is not processing the audio when played through poweramp player. Also I have made the required audio settings in poweramp.
Any help in this regard is appreciated.
Which su you flashed?

I got it to work with Magisk v11.6 using this zip - Arise Magisk Compatibility Module v2.2 LS
cant seem to find the source thread though.
No need to restart everytime.

Well, I flashed superSU after uninstalling magisk, the V4A app that I flashed earlier still worked fine. So, I didn't bother to check if it worked on a clean install.
same problem at me. i've tried any version of v4a but nothing work. Suggestions?
I have same problem with SuperSU 2.79. always have to exit viper then restart to begin processing. Makes no difference with which Music player i use it always stops processing. Didnt have this problem on aexop ROM though. I also tried using magisk but had same result with failure to keep processing enabled.

Did you installed viper4android magisk module? I also noticed that on some roms audio modification magisk module causes problems with viper.

I don't know, maybe. I am using Magisk v13 + Busybox by osm0sis (magisk module) + Viper4Android FX (magisk module) + Viper4Android v2.5.0.5 (flashable zip).
I also have FX Compatible Mode set to Compatible in Viper settings and Music FX disabled. My current ROM is Pure Nexus.
The Arise Sound System zip flash install works much better:
https://forum.xda-developers.com/android/software/r-s-e-sound-systems-auditory-research-t3379709
But they leave out the critical step of modifying the arise_customize.prop file and placing it in internal storage
BEFORE you flash (SMH).

...but I'm having the same issue - no processing, then it works, then not.
MediaMonkey Pro is my music player, and I really don't want to use another one.
Grrr...

Have you tried using a different music app like the Google one. Always found it a struggle with power amp.
Most of the magisk modules will fail on the moto g5 plus. You need to flash a custom kernel in order for the modules to work, including magisk hide.

Disregard the posts from a long time ago and install this (see screenshot) from the Downloads section of Magisk (for me it appears in Modules because it's installed), it's very easy and works perfectly.

Thank you for the reply. It seems Viper is not working properly even if I did it in your method. Should I uninstall audio fx?

Yes, you must have something conflicting, possibly from already trying other versions but hard to tell what. I've been using either that or the one by ShadySquirrel (also in Magisk/Downloads) for several months on dozens of installs of the popular nougat & oreo ROMs with zero issues.
Try a fresh install after full wipe (dalvik/system/data/cache) - install only ROM + gapps (no custom kernels until after Viper is working) - boot once to system/desktop to make sure all is ok but don't install anything yet from playstore/SD/etc - install Magisk in TWRP, reboot system - open Magisk, do any requested updates, check safetynet fully passes (if not install safetynet fix or will get errors trying to install from Downloads) - find Viper in Downloads, choose to install (not download), when finished choose reboot - open/configure Viper, check on something very basic like default music player, should be working - keep checking as you install apps/kernels/etc so that in case something conflicts you'll know what.
Hi, I am using Viper4android Fx for Magisk (created by ShadySquirrel) on Xiaomi Mi A1 which was rooted systemlessly by Magisk "patched_boot.img" method. I have installed Magisk SELinux permissive script and Busybox through Magisk Manager. Now whenever I am installing V4A Magisk module, it works for some time and then it stops working with a pop up like "Update/install driver". But when I am trying to update or install the driver, it fails with an I/O error. Reboot doesn't solve the problem. I read on Xda that SELinux permissive script needs to be enabled and storage permission needs to be given to V4A. I have both active. But still, the problem persists. If I uninstall V4A module and reinstall it, then it works, but for a few days. Then the problem starts again. Is there any workaround?
Note that, I have stock android 8.0.0 with no custom recovery and no custom kernel.

I'm not using viper actually, I stay with Dolby on Oreo with my a1.
But I guess you will find working viper and answers on the link.
I guess I have the same problem here. When I try to install Viper4Android or Viper4Arise modules, phone starts crashing with "Dirac Control Services Stopped Working" showing up every few seconds. I really love Viper and I don't want to move from Stock ROM or install any kernel. Any clue on that?
Maybe Try selinux switcher and viper4android by viper520, zhuhang and others (i Click Three Times Volume Up)
Has anybody got working V4A+Dolby Atmos on the latest stable Oreo (CRAP)? V4A is working fine using ahrion's Magisk Module but I couldn't get Dolby Atmos to work.
What I did:-
1. Installed Ahrion's Viper4Android Magisk Module.
2. Reboot.
3. V4A working fine (tested using Spotify & Musixmatch).
4. Installed Dolby Atmos from this thread - https://forum.xda-developers.com/android/software/app-dolby-atmos-axon-7-oreo-port-t3740508
5. Reboot. Got stuck in bootloop.
6. Went to recovery deleted Dolby Atmos Magisk Module.
7. Was able to boot again successfully but with only V4A (no Dolby Atmos)
If anybody got it working then please share your method here.
DA not working now on Oreo S8
I have tried 3 times in pixel experience, resurrection remix and lineageos 15.1
1. first kenzo must be in rooted, use magisk
2. Download dolby atmos for oreo 8.1 by emime12
https://forum.xda-developers.com/redmi-note-3/themes/mod-dolby-atmos-oreo-8-1-t3734338
install it manually via TWRP
3. download latest viper4android from magisk (8 mei 2018) install it from magisk
4. download audio modification library from magisk and install it from magisk
5. download Any sound mod + dolby + viper uninstaller.zip from :
https://forum.xda-developers.com/android/software/sound-mod-viper4android-oreo-t3734107/post75171306
6. flash Any sound mod + dolby + viper uninstaller.zip manually via TWRP, why??
this will not remove dolby or viper4android, but this will remove some bugs that make dolby & viper crashes
7. if there is already an audio fx app in your rom please do not activate it, as it will make dolby not work
8. if everything is installed do not play music first but first turn on dolby and viper
9. if when you listen to music, you turn off viper4android and turn it back on viper will not run. if you want to turn it back on you must stop the music first, turn on the viper and play the music again
***** Sorry, my English is bad *****
anyone else tried it?
