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.

Ever since Android 5.0 Lollipop released, getting ViPER4Android to work magic on music played on Android devices has been a challenge for the users. The change of SELinux policy from permissive to enforcing broke ViPER4Android pretty bad.
But soon came a workaround to use ViPER4Android on Lollipop while still running SELinux in enforcing mode (to ensure device security). The trick worked on Android 6.0 Marshmallow as well. But with Android 7.0 Nougat update, folks over at xda have came up with an even easier way to get ViPER4Android working with sepolicy set to enforcing.
For the unknown, ViPER4Android is the mother of all sound MODs available for Android devices. And it’s not device specific. You can install ViPER4Android on any Android device and enjoy rich music experience on your device without spending a single penny on sound component hardware upgrades.

User guitardedhero over at xda has shared a zip file of ViPER4Android that you can install/flash using a custom recovery like TWRP on your Android device. This zip installs ViPER4Android on Nougat without a flaw. We tested it on our Nexus 5X and 6P running the latest builds of Android 7.0 Nougat.
Note: The ViPER4Android files and installation instructions shared on this page might also work for Lollipop and Marshmallow releases of Android.
Grab the recovery flashable ViPER4Android 2.5.0.5 zip file from the download link below and follow the quick instructions to get it working on your Android Nougat device.

How to Install ViPER4Android on Nougat
Make sure you’re rooted and have TWRP recovery installed on your device.
└ For help, follow our guide on How to Root Android 7.0 Nougat.
Download the ViPER4Android_2.5.0.5_guitardedhero.zip file from the download button above and transfer it your device’ internal storage.
Boot into TWRP recovery and install/flash the ViPER4Android_2.5.0.5_guitardedhero.zip file to your device.
Reboot phone.
Download/install a root file explorer app (we recommend ES File Explorer).
└ On ES File Explorer, swipe-in from left and turn on Root explorer feature. And don’t forget to grant root access when asked.
Now using your root explorer app, go to /vendor/etc/ directory on the device and rename audio_effects.conf to audio_effects.conf.bak.
Open ViPER4Android FX app on your phone (it installed when you flashed the zip file in step 3 above).
You’ll get a notification to install V4A driver. Select YES.
It’ll take some time to install V4A driver, and while doing so it might even look like it’s stuck but you don’t worry. It’s doing its job and will finish soon.
└ If Android gives an error that the app has stuck/stopped. Be sure to select the wait option, don’t force close it.
Once you get the Driver installed message on screen, reboot your device.

That’s all. Enjoy ViPER4Android music MOD on your Android device running on Nougat.
Seems like Development has moved onto A.R.I.S.E which takes the best of this and adds stuff on top of that. The ARISE thread include flashable builds and instructions which work perfectly fine on nougat.
I have rooted the device, and currently using Nougat RR ROM. But ViperDD is not working properly on device. Busybox also installed, the driver status shows Abnormal. Any Solution for it.
Uninstall Viper driver, reboot and then go to /system/vendor/etc and rename audio_effects.conf as audio_effects.conf.bak, go back to Viper app and try to install the driver or just check the driver status, should work with that

I would also check that your kernel is set to permissive, not enforcing. Heard that causes problems as well.
Also, you might like to install SuperSU from XDA rather than using the inbuilt CM root, as it appears to resolve the Abnormal error you're seeing. (credit: https://plus.google.com/communities/104675617308252943432)
The stable SuperSU is herehttps://forum.xda-developers.com/apps/supersu/stable-2016-09-01supersu-v2-78-release-t3452703. I've installed the TWRP version of SuperSU on my XT1642 Plus on RR 5.8.0 24/01/2017 build (after making a backup in TWRP) and flashed Viper4Arise (i think it's based on Viper4Android), which works well

The Arise Sound System zip flash works much better:
https://forum.xda-developers.com/and...earch-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).

If you use Magisk, ViPER4Android works flawlessly on nougat ROMs using the ViPER4Android for Magisk v14 module found within the downloads section of Magisk Manager, just install and reboot, nothing more required.
Not working for me. Was working on 8.0 roms with magisk installer but now it says no driver installed no matter what I try. I saw a thread on the the pixel 2 forum where they fixed it by moving files around with a root file manager but they said not to try it on non pixel device. I doubt the file structure would be different so I'm not sure why. Might just try it....
Suggestions?
Edit: BTW I'm using aicp

I got it working on Cardinal AOSP 8.1 64 via the V4A for magisk 15+ magisk module.
I'm also using AICP, I've flashed the files above and also try the magisk version, none of them worked, viper keeps asking me to install drivers, if I do it from the app, I get and I/O error :_
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)
Hello Everyone.
The first beta version of OxygenOS 12 was released, and as usual I ventured to install V4A, unfortunately I was not successful.
I tried several ways to make it work. I believe that I'm not getting it because of the Dolby Atmos that already comes in the Rom system. If anyone has a solution for this it will be of great help. thank you for the attention.
