Try this after Rooting, Change to permissive mode with SELinux Mode Changer https://play.google.com/store/apps/details?id=com.mrbimc.selinux from the Play Store.
Enable developer options and Uncheck - Use Nuplayer.
Open Viper4Android and under settings switch FX Compatible mode to Compatible.
and finally don't speak abt LP on xda.

I know, only mentioned it because i thought maybe it could have some relation to my problem, don't know

Finally got it working, using the SELinux Mode Changer + Busybox On Rails

Viper4Android 2.5.0.5 Magisk module does not work

I'm trying to install the Viper4Android 2.5.0.5 module in Magisk. I installed the module and the app and then rebooted, but the driver status in Viper4Android under enabled indicates a "no".
I've tried some of the settings, but it does not seem to work. The sound is all the same. Any idea how to get this to work? There were no additional instructions for getting V4A to work.
Nexus 6 running Pure Nexus 7.1.2 with Magisk version 12.0

I've had great success on several different devices with this module: https://forum.xda-developers.com/apps/magisk/module-viper4android-fx-2-5-0-5-t3577058

I can confirm that the above link works great..

I was hoping I didn't have to use that workaround, but I guess I have no choice. I don't know if anyone will agree with me, but I find it annoying to have to decipher and read through all these guides and forum posts to figure out how to get something to work. I wish things just "worked".

Everyone has different devices, different setups, etc. It's never going to "just work" easily for everyone. That said, the link above works great and doesn't really have much reading to do....
Only issue I had was it not working initially, but I set the mode to "compatible" instead of "normal" it instantly started working. In case you have issues with it not starting like I did.

Hello, I have a OnePlus 3T (Oreo - 8.0.0 - OxygenOS Open 20 ) I was in the big sh*t installing this app but now it's working so what I do ?
I simply install 4/5 things :
- Viper4Android APK here ( http://www.mediafire.com/file/xonl4jha2e4vez1/ViPER4Android_FX_v2505.zip )
- BusyBox you can get it on the Play Store
- This Magisk module for OP3T but if you have an other phone search an other compatible module ( https://androidfilehost.com/?fid=673368273298977808 )
- The SELinux Switch [IMPORTANT] ( https://forum.xda-developers.com/devdb/project/?id=22073#downloads )
UNINSTALL ALL PREVIOUS VERSIONS OF V4A ON YOUR DEVICE.
Now I'm gona show you how to get this sh*t working
Simply install unzip the Viper4Android folder and install this apk :
ViPER4Android_FX_v2505_A7.x_Nougat_IO_test_fix.apk
(Maybe a newer version can be delivered in the future I think you can install it).
Then install BusyBox.
Open V4A and install the Drivers.
When it's done go to Magisk -> Modules -> + and install the zip module for your device.
/!\REBOOT /!\
Finally you just have to install The SELinux Switch.apk and switch your SELinux to Permissive (maybe you have to reboot but for me when I reboot my SELinux go back to Enforcing SELinux so I switch it back when I reboot).
[Note : I don't know if it's important but I was flashing a zip of V4A that's install me V4A as a system app and it wasn't working (error I/O) this is not important but it maybe install me other files so maybe you have to do this if it's not working at the end].
V4A is working now (don't forget to switch off your stock equalizer in Settings -> Sound -> Balance)
If you have any problem or questions contact me.

My dude, you are doing way more then you have to. Just install Ahrions magisk viper module. It has all the patches for OOS Oreo to work (it seems OnePlus made it impossible for viper to work on Enforcing with their Oreo release -.-)

No because V4A is not working when SELinux is on enforcing bru this is why I install the switcher and it's working but if a problem comes I will test with your module.

Look at the previous link in this thread. That's the one (it requires Magisk 15+ to work).

[OOS5] Audio mods causing OOS to factory reset

Hi,
Just found a strange bug on OOS5 OB1. When installing ARISE, (core and v4a), OOS is rebooting fine then after few seconds a dialog is opened for factory reset : https://i.imgur.com/KCM2EZI.jpg
Same thing is happening with other audio mods such as XTREMEMusic Mod.
I suspect that it is because Dolby's apps are beeing uninstalled while mods are installing so OOS wants a factory reset to recover it.
Anyone have the same issue? And a working audio mod?

Uh sorry i forgot to mention i don't use V4A... :/

I solved V4A by setting selinux to permissive, all is good now except some force closes but the sound is really awesome, thanks for having shared the project ahah

Ainur should be fine regardless of android versions, tho bugs may come out

Just use :
1- [MODULE] Magisk SELinux Permissive Script v1.1
2- Install the Viper4Android 2.5.0.5 v2.2 on MagiskManager repo
All is fine, no bug, no force close

Dolby Atomos vs Viper4Android

Hi, i was wondering which one is superior and if so why?
I see people installng both , isn't one of them enough? Or am i missing something here.
I currently have atmos installed on nitrogen oreo 8.1 on shamu.
Thanks

I use both on my OP3T and they work quite well together.
Edit: and since the latest update to the Unity V4A Magisk module, also on my Nexus 6.

Well i installed Dolby Atomos via Magisk , using Magisk module . If you are rooted and have Magisk installed you can search for it and install it.

Saw this ...

V4a is not compatible with emui 8 because v4a uses 32 bits audio files and emui 8 only supports 64 bits files

There is Elemental ROM in Development section of the device, it is a rework of EMUI 8 and has V4A in it, I couldn't install that ROM but I think it is still possible to install it somehow on EMUI 8. I really would like to know how.

you need to set SELinux to permissive, and rename audio_effect file in vendor/etc folder

There are apps for that, SELinux switcher for instance, also you can use the magisk module. But even though you do that Viper will not work on EMUI 8.

SELinux can't be forced in oreo (damn huawei) , you need to build kernel source with CONFIG_SECURITY_SELINUX_DEVELOP=y , then you can change to permissive.

Has anyone figured out how to install Viper4Android on Oreo? It is really the only thing stopping me from using oreo as a daily driver

Im using huawei mate 9, with emui 8, the only kernel for selinux permissive (but show as enforcing) hyperplus kernel.. Able to install viper driver, but can't open the app... I think a full permissive kernel should work.. But currently no developer build for mate 9, sad

Guys, currently there is no 64-bit driver for Viper, so no EMUI8 users can use Viper, sadly. I've tried contacting the developer on two separate emails but received no response. Does anyone know of any other sound mods that can be a good replacement?
