This is a guide to install mods for OP8 Pro that improves the stereo speaker setup. I have helped many OP8 Pro users to achieve this. Some other OP users as well.
Custom ROMs that work with this mod (TESTED):
Stock Oxygen OS 11 (not 12/13)
CrDroid
Evolution X
*I am not responsible for bricked devices, damage to your device*
I am here to post my method for anyone who is interested. I have tested this myself and helped others to do this.
Issues:
IMPORTANT:
Setting SElinux can have security issues noted by @topjohnwu.
Viper4Android can be installed with SElinux Enforcing and Permissive. Choose SElinux Enforcing not Permissive
Installation Method:
With new Viper4Android Repackaged module
If you have other audio mods
Download Audio Modification Library from the links section
Install Audio Modification Library, reboot and disable it
Otherwise, skip to the next step
Download the latest Viper4Android Repackaged module from the links section
If you want to use the extra V4A features...
Download and extract all the guide setup or the other .zip file I attached below on your device. You need the DDC, Kernel and Preset folders.
If you downloaded and extracted on a separate device: Connect your device, copy and paste the folders into your internal storage.
Otherwise, skip to the next step
Install the Viper4Android Repackaged module.
Reboot.
Open the app and grant root
DISCLAIMER: On custom ROMs or certain devices, the drivers are installed, but NOT working properly after reboot. Just continue the method and comment if there are issues once u have finished the method.
If you have Audio Modification Library installed
Now go into magisk manager, go into modules and enable AML.
Reboot
Otherwise, skip to the next step
If u used the guide setup.zip file: in V4A app just press the file icon for presets and choose the preset.
Now make sure V4A driver is running (read Notes) and go into convolver -> impulse response. Choose any kernel, and done. OR choose the preset for that and done. If you have issues, make sure legacy mode is on but it is on by default.
Choose to your heart's desire if you downloaded all the V4A DDC and kernel files.
I personally use Dolby Digital Plus - Centre kernel
Done, also post the settings or kernels and your thoughts.
I also attached a screenshot of my configuration
Also, for new users if u connect your earphones like via headphone jack, USB-C or Bluetooth. You can tweak those as well. Not just your SPEAKERS! BUT some earphones can be damaged as well, so tweak them at your own risk.
After much tweaking myself. I think I have made my speakers much better on my 8 Pro.
I have attached a screenshot to the thread at the bottom. I have attached a screenshot for my headphones too!
I have added the individual settings as well. If u want to tweak them just press the text and it should expand.
The toggles I have on are for my speakers:
Master Limiter
Playback gain Control: Strength: 2, Maximum gain: 3X, Output threshold: -1.9dB
Convolver: Dolby Digital Plus - Centre, Cross Channel 100%
Speaker optimization
I have also tweaked my Bluetooth earphones as well with a DDC and the screenshot is attached below. I recommend Dolby headphone Live, but that's up to you.
U can add files in the DDC folders in the Android folder, but reboot and then tweak to see the difference. U CAN RISK DAMAGE IF U TWEAK TOO MUCH
You have completed the guide and can now experience dual/stereo-like speakers on your OP6/6T.
Enjoy
If anyone has any issues with this guide. Post a message and I'll get back to you
Notes:
Viper4Android sometimes doesn't turn on properly. So, play music and open the app to check the driver. The Driver status if it's working (NEON enable: yes, Enabled: yes, Status: Normal) and turn on the master limiter to see if there's an effect. This should give you an indication if V4A is working or not
I have attached DDC files below and you do the same thing with kernel files, but they are used for headphones.
You can try and use the preset (profiles). You don't have to use the preset files, they are there to make the setup easier for those who don't want to tweak too much.
If u want to add the custom presets:
Choose the specific presets u want
Transfer them into Android -> data -> com.pittvandewitt.viperfx -> files -> presets
Transfer the V4A.zip in internal storage
Reflash the V4A.zip again and reboot
Install the V4A driver again and reboot
V4A driver should be working, check the presets and it should be there
Enjoy having your presets
Fix for V4A:
There has been noted issues during the installation with V4A. If you experienced a bootloop after installing V4A in magisk...
Boot into OrangeFox, -> advanced -> file manager -> data/abd/magisk/modules and delete the V4A folder.
Reboot to system, install the module in magisk again and reboot. It should install.
Another issue was that V4A driver is installed properly, but there are no enhancements to the sound. To fix this, go into settings -> turn on and off the legacy mode toggle. This should restart the effect and make it stay on.

Updates
10/9/22 - Removed step for the option to choose Enforcing or Permissive for SElinux during Viper4Android module install. It has been removed
15/1/22 - Released the XDA thread that is a guide to install Viper4Android for the OP8 Pro
Not sure about the OP8 sadly as I don't own one and this guide could be used for other android devices too
This guide is a duplicate from my previous dual speaker guide for the OnePlus 6/6T. But this guide can be used for other android devices or users who just want to install Viper4Android
2/11/22 - Updated the Installation method as I found a new updated version of Viper4Android (Repackaged)
Tested the module and it works on Android 12 and Android 13
AML does work on Android 13 as well
3/2/23 - Updated the method Viper4Android method as repackaged installs the DDC, Kernel and preset files during installation.
So, u can just download and extract the compressed .zip file into internal storage and V4A will install the files for you during installation.

You are describing a method here with 'not SElinux Permissive'

2. Choose the option to install with SElinux Enforcing. When installing the module, there is no such preset. Basically, I've tried everything. It doesn't work... you need to somehow change SElinux

U could just uninstall the v4A module in magisk manager. Then try again and choose SElinux enforcing. Also, this guide is for the 8 pro not nord 2. I don't own a nord 2 and only tested on the 8 pro

First of, what version of magisk are u using? I only use stable (V23), where are u getting the viper4android .zip file/module? I have added the download link in the thread. If ur getting it from magisk manager, the one to use is the viper4android FX (Not legacy and not XHiFi)

Yes, I'm using version 23 of Magisk. I tried to install viper4android FX (Not legacy and not XHiFi) from the Magisk repository, as well as separately downloaded zip viper4android FX v2,7,2,1. But it doesn’t give a choice in which mode to put it, it just puts it all. Android 11. My English is bad, maybe I'm not expressing myself accurately, sorry. Also install the AML library. I saw how they put it on Pixel 3 / 4a, but the version of magisk is exactly 21.1. I can't downgrade.

Do u install it in magisk manager? if u installed it properly (without the magisk manager crashing) and leave it to install... The install terminal should show a question + options for u to choose if u want SElinux enforcing or permissive. U choose by pressing volum up or down. Up for enforcing and down for permissive. The the reboot button should show up. Maybe take a screen shot and show it here

I previously checked my comments and found that V4A can cause SElinux to be permissive on some OSs. There's a magisk module that will set your SElinux back to Enforcing with no app needed and it's a just a command that will set your SELinux back to enforcing during every boot. https://forum.xda-developers.com/t/...b-root-selinux-permissive-enable-eng.4050041/

ps000000 said:
May I add Android 12 instruction to this thread.
(Only custom 12 ROMs since ColorOS12 I cant enable permissive.)
You should goto app settings Unrestrict battery usage for both SELinux and Viper.
1. Install SELinux apk enable permissive on boot.
2. Magisk install Viper 12 Fix module no reboot
3. Magisk install Viper
4. Open Viper grant root and then press ok phone will auto reboot.
5. After rebooot pen Viper setting enable Lagacy mode .... done.

Hey guys.
So the app is unable to install itself via root. My guess is that it requires to be installed via flash. Unfortunately, the flashable mod is not compiled for intel-based android devices, but rather only for ARM and ARM64. Does anyone know of a workaround for this? I like the audioFX features alright, but I wish for greater reverberation and IRS controls.
Hi,
If you get any not responding message during driver install, ignore it and reboot.
If you can't disable AudioFX, set FX Compatibility Mode in V4A to Compatible.
Regarding flashable zip:
Ask your mod developer to make it one for x86 devices. You may need to give updater-binary from x86 flashable zips.
Sent from my GT-I9500
Hi All,
I'll be straight forward - can someone point me to the right direction, where I can find flashable zip of Viper4Android 2.5.0.5 audio mod, which would be *perfectly compatible with LineageOS (April latest releases) on OnePlus 3?
*perfectly - means same as on FreedomOS ROM, which means it works fantastically well with ALL apps. Few months ago I found a flashable zip which makes spotify and few other audio apps work with, but not youtube and I am unable to find it again. Would be great if you provide flashable ZIP, so I don't need to install driver after each update, but instead flash zip.
I'm currently using arise 3.31
Found here
Use aroma and choose whichever options you want or take the customize prop file out of the modular zip and follow its instructions to get it to flash what you want. Just make sure with whichever route you choose, to select the deep buffer remover option and it should process in other apps. Screenie attached showing I'm processing fine in YouTube on Resurrection Remix 5.8.3 (based on LOS) with v4a 2.5.0.5, deep buffer removal, musicfx removal. I'm also using magisk v12 compatibility module 2.3 LS (found in the arise thread but I don't know how much that one matters tbh with RR but I believe it's required with LOS)
I have been trying to install v4a presets on my Oneplus but I cant seem to get them to work. I tried a method from another post on here which said to just make a presets folder (/internalstorage/viper4android/presets) and to copy the xml files into there, but then v4a didn't recognize them.
I also installed a folder of like 1600 presets from here too and looking through them I noticed they all have similar names like "headset.xml" or "bt_a2dp.xml" so I was wondering if that has a meaning or if I can change them since I want multiple files from the collection.
I am running lineage o and I am rooted on my oneplus 7t.

Uhm can you elaborate
Use selinuxchanger.apk to switch to permissive and then V4A will work

Thanks for the suggestion, but I looked into it and apparently the version I'm using works with enforcing mode on. Also my problem was just with the presets which I managed to fix by just reinstalling the magisk module while keeping my presets folder in the v4a folder.
I still have not figured out what the filenames mean but I think it's just the type of output device while the folder gives it the name.
Still don't really know what SELinux is so I'm going to keep that on default for now. Seems to be a security protocol so I don't know if I want to turn that of.
Anyway thanks again for your help
Hey man maybe you can help me
I need a magisk flashable batch script for changing / replacing a value in many xml files per batch i wont to help the guys from viper4android maybe you know the tool following operations : open file - jump to row / string - read value - calculate new value - write value - save file - jump to next xml and so on.
Description : The values for surround section changed from 120 - 0 130 - 1 140 - 2 150 -3 160 - 4 170 -5 and so on until 8 old values : 120- 200 new values 0- 8
Maybe you can help me with this many people would be happy to solve the wrong conversion issue of viper4 Android presets or maybevyou know somebody
NOT RESPONSIBLE FOR ANY MALFUNCTIONS. MAKE BACKUPS BEFORE FLASHING!
Dirty flashing over previous OS version (~PE 12) may cause bootloop, clean flashing is recommended.
Formatting data partition to F2FS requires internal storage to be fully wiped!
Regarding KernelSU
- KernelSU module system is not (yet) fully compatable with Magisk's module.
- Installing Magisk over KernelSU-enabled boot image or vice-versa will make device not bootable. If it happens, just flash magisk uninstaller or reflash ROM.
- If you want to use KernelSU, flash boot-ksu_{ID}.img from the link below.

Original Post
Removed magisk and dirty flashed from previous build on dumpling but modules are not working with KernelSU. Installing them with KernelSU manager but module list remains empty even after rebooting. Tried with a clean flash and same result.
/data/adb/ksu/modules/ subdirectories only contains module.prop and an empty update file.
However, su and root privilege work as expected.
Is there something wrong with my device, KernelSU integration in this rom or KernelSU itself?
I can provide logs from KernelSU manager if needed.

KernelSU's module system is still in development, and it is changed to store modules in /data/adb/modules just like magisk. Each magisk module's install script might need to be altered a bit for KernelSU.
For more details of module system, check the wiki.
https://kernelsu.org/guide/module.html
Works very well, updating from pe13
KernelSu's module function didn't work, I hope you can fix that in next build
--4/4
I created a pull request from my fork, it fix the module function.

Just upgraded from stock rom. So far, everything works fine and super fluid! Even the better compressed x265 video files plays smoothly on the phone, they was not with the stock rom.
But I have a problem with playing HDR video files. They are not bright enough even on 100% brightness and backlight, while the normal SDR videos are perfect. I used to play these video files from the internal memory with the stock rom, but they was enough bright. So this is something that the new rom changed.
*Tested with VLC and 2 other video players.

Solution: set HW acceleration in VLC from "full hardware" to "decode acceleration".
In this way the image brightness is perfect but the movie still fluent. On other players deactivating HW acceleration did result a not so fluent playback.
Hello to everyone!
Here is a new Grass kernel line, which work with Kernel SU on POCO M3 (probably all chime).
It provides systemless root access on a kernel level for chosen apps only. No root access visible in system - nothing to hide.
Installation:
If you have magisk - flash uninstall.zip in recovery; then flash stock boot.img from your ROM; last flash grass-kernel.zip.
Manager run from apk file.
If you want back magisk with it's modules, you can install it from magisk.apk, grant root access from KernelSU manager, than you can patch boot via direct install (recommended). After reboot you can add your favorite modules like usually in Magisk.
The kernels are in next post.
Don't forget to change extension (apk->zip)!
Update from 19.05:
So, kernels are here:
Change extension from .apk to .zip, flash it in recovery and enjoy!
[email protected] is the latest one.
Will upload here one more time kernel for juice/chime and latest KernelSU apk:
Latest version of Grass kernel:
Optimised very good and working with 0.6.0 app. ver.
Also latest zygisk for kernel SU:
Version 10999:

I'm wondering about root detection... You have double root(KSU&MagiskSU)...
Which one controls the root actually ? KSU has the better prevention from root detection but MagiskSU hasn't. If MagiskSU controls the root, it seems not to be a good idea ...
