After doing this, V4A always asks me to install the drivers. It nevers gets installed at all. I tried everything, but I can't get this to work on the A5 2016...

I installed viper4android on two different galaxy A5 2016 A510FD running android 6.0.1 with the methode from here
http://forum.xda-developers.com/showthread.php?p=68886055
Both device running V4A perfectly. Updated binary only once with first startup of V4A

Okay, on MM stock rom, just tried installing V4A on priv-app, then flashing this zip, and it finally worked! Also had to add these to build.prop or else I'd get "Processing: No" constantly after plugging my headphones in and out:
Code:
## ViPER4Android Build.prop Tweaks
lpa.decode=false
lpa.releaselock=false
lpa.use-stagefright=false

[GUIDE] Viper4Android Systemlessly

With Magisk 11.5 came many bug fixes including for devices that have a separate vendor partition. We can now use Viper4Android systemlessly with the magisk module. This will not affect the lockscreen visualizer or the audio fx tile visualizer. So we can have viper4android without sacrificing these features.
1. Install magisk 11.5 in twrp recovery, reboot to system.
2. Install latest magisk manager from playstore or apk
3. Open magisk manager and select "downloads" option in menu pane.
4. Search for "Viper4Android FX" and click the download button then click install.
5. Reboot.
6. Open magisk manager and select "downloads" again.
7. Search for "Viper4Android FX" under "Installed."
8. Tap the tile (not the download arrow)
9. Click the link that says "download the latest apk here."
10. Install apk you just downloaded.
11. Enjoy Viper4Android systemlessly on Redmi Note 3.

It all depends on what headphones you are using and what quality the music is, i.e. lossy or lossless etc. Just play with the settings and find something you like (our ears aren't all the same).

I went directly to aosp based roms as soon as I got this phone. Sorry I can't help.

It shows driver installation failed due to busybox. But I have installed the recommended Busybox.. Please help

i know magisk is to hide root. but i didnt know about it has viper capability. now my speaker sound louder. thanks.

Thank you for the guide, followed it step by step and it works perfectly!
I just had a question
I am on XenonHD so if I flash an update, I only have to flash magisk again right? Or must I do something special for V4A

Viper4Android version for B29?

I'm on B29 ZadMix and tried to install Viper4Android v2505 ("ViPER4Android_FX_v2505_A4.x-A7.x.apk") and while the apk runs fine, it gives an error about installing the driver. Any suggestions? Is there any special version for the Axon 7?
I did try installing BusyBox first

go to*/vendor/etc/*directory on the device and*rename*audio_effects.confto*audio_effects.conf.bak
Open*ViPER4Android FX*app*on your phone
You’ll get a notification to install V4A driver. Select*YES.

Did not work for me.
I must say also that my r/w does not seem to work since I updated to B29.
I have tried adb reboot disemmcwp and that did not help.

Hey, go to
https://www.androidfilehost.com/?w=files&flid=118862
Download ARISE Sound Systems 2.4.zip and install it with TWRP.
Drivers are already included. This shoul help.

What worked for me
I don't use B29 at the moment, but these steps fixed all my Viper4Android problems (V4a + Dolby Atmos):
0. Dirty-flash B29 to fully uninstall all previous versions of V4A mods.
1. Make sure you're properly rooted, preferably SuperSU (although Magisk works, too)
2. Install BusyBox (again, make sure you install it form within the app itself)
3. Download and install SELinuxModeChanger and switch status to Permissive.
4. i. Download the latest version of V4A from here. It is AROMA-based and by far the easiest method I've ever used to install the package.
ii. Download the Dolby Atmos driver for LeMax 2 from here. The ZIP for Axon 7, surprisingly didn't work for me.
5. Now reboot to recovery and flash the Viper4Arise ZIP first. Kindly choose the New User option from the initial AROMA screen to make sure you get the full details of what you choose to install. After flashing, reboot the device and check driver status from within the app. I should say 'Normal'. To confirm I play an audio in the background and check to make sure 'Processing' : Yes.
EDIT: Step 6 is only for when you're on a custom ROM which doesn't have Dolby by default.
6. The dax_lemax2_v2.2.zip ZIP is for installing the Dolby Atmos Add-On. The official one from V4A, again, didn't work for me. Reboot to recovery and flash that one, too.
Your phone should now have both V4A and Dolby Atmos.

The question is how are you rooted. If you use SuperSU then I would suggest to use this Viper4android. You can use it together with Dolby Atmos from B29 and you can run it while selinux is enforcing. I'm using this setup at B19 (Android 7.1.1) and it works like a charm!
If you're using Magisk you can download the Viper module within the Magisk Manager.

Viper4Android for Moto G5 Plus

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?

cant seem to find the source thread though.
No need to restart everytime.

Did you ever get it working better with superSU? I couldn't get it to work at all.

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've tried whit magisk. Magisk doesn't work and then i have used classic method. Is this the problem?

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).
http://www.droidviews.com/install-arise-magnum-opus-sound-mod-android/
...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.

Problem With Viper4Android FX

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.

https://forum.xda-developers.com/apps/magisk/module-viper4android-fx-2-5-0-5-t3577058
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)
