So i've seen a lot of viper/viper4arise ( + Dolby + etc ) on many threads...
with maybe way too many versions..
On 7.1.1 default OOS 4, I have mine worked just fine with the one coming from magisk repo.
I've tried the one from Magisk 14.5, processing says Abnormal..
and i can hear crackle sounds in the background when playing music.
Decided not to clutter my magisk modules with install/reinstall, i immediately restore from nandroid backup with clean magisk
( plus one google camera patch module only. )
So have anyone got anything worked on our new OOS 5.0 ?
preferably with Dolby atmos working ? i've never tasted this one on my 1+ device ever...
I also couln't get V4A to work with Magisk so I tried the one that I also have used in 7.1.1 and it seems to be working without any issues for now.

If you're talking about the repo on the Magisk Manager, those V4A versions are horribly outdated.
Try the modules by ahrion, downloaded from the thread: https://forum.xda-developers.com/apps/magisk/module-viper4android-fx-2-5-0-5-t3577058
I personally have v2.0 working perfectly with Magisk 14.3. But also needed SELinux permissive module to process properly. Yeah, I know, a of folks are not going to want to set SELinux to permissive. But I'm just sharing what worked for me.
v2.3 wouldn't work properly for me. But one of the devs told me that I should delete all V4A and AML (Audio Mod Libs) and try to install through TWRP. Haven't had a chance to retry it doing all that. If you still have troubles, you can post the TWRP recovery log on the above thread, and they will try to help you out.
Dolby Atmos does not work on Oreo. Do NOT flash, bootloop is a possiblity.
This is how I got V4A working with OOS oreo. I had to set SELinux to permissive.
1. Use Magisk v14.5
2. Install 'Magisk SELinux Permissive Script' module by jman420 from within magisk manager (Modules -> + button -> select file)
https://forum.xda-developers.com/apps/magisk/module-magisk-selinux-permissive-script-t3577549
3. Reboot. Optional - Install 'Display SELinux status' module in magisk
4. Install 'Viper4Android FX for Magisk v14+' v4.0 by ShadySquirrel in magisk manager. You can get it from Magisk repo. (Other V4A modules might work too.)
5. Reboot and voila!
Okay... so far there are 3 alternatives to get this audio mod in Oreo
I will try them and test...
Let's say, this is my attempt to keep track of how to install in oreo..
Thank you guys for all the suggestions ( and warning ! )

did this version require any SELinux permissive trickery?
Brian
Yes it does but you don't have to install separate apps or magisk modules to archive that. After you flashed the whole thing, open Viper - Settings - Turn on developer mode and disable SELinux. That's it.

On my attempt with your method, It installs just fine with TWRP, but fail on running.
- Installed just fine with TWRP, no errors. (*)
- Reboot, but i can not find the V4A apps in drawer...
- So i opened up the zip file, extract the APK from v4afx-v2.3.zip/system/app/ViPER4AdnroidFX.apk.
- Install it manually, then it shows up in drawer.
- Everytime i try to run it.. it keeps asking to install drivers. I assume because it wasn't install in /system
( confirm install, reboot, then it asks to install again when i open it ).
So i decide your method does not works well on my device... or i may have missed something in the steps.

Your method works OK on my device :good:
so we are only limited to v4A ? no Arise, or Dolby atmos ?
i see some OP3T users saying they got it working on their device with Oreo ..

It said aroma, i'm on stock ROM.. is it safe ?
I will take nandroid backup and try it...
EDIT:
My mistake for not understanding aroma installer.
Tried your method, only install v4a 2.5, and DD Plus..
No errors, when playing music, V4A says abnormal. Second tries, i can not even get the Driver Status to popup.
Dolby Digital seems to work, but it quit everytime i changed the mode, but sound does noticably change.
*rolling back to nandroid backup*

You tried ahrion's module, v2.0 like I said (you listed all other version number details but that one)? Newer ones don't work for me; I tried 2.3 and 2.4, and same error you have - no V4A app in app tray.
Also, I'm on Magisk 14.3 (as mentioned) so another variable there.

i've managed to get mine working as per Post #5,
i saw there's a new version just came out from ahrion ( v4afx-v2.4.zip , 11/30/2017 ).
I might gonna give it a try also with magisk 14.5...

It's works!!!
Magisk audio mod library on reboot install viper cancel reboot uncheck active on audio mod library in magisk re install viper and now install viper dll reboot
All features are working. If you follow the process as described, viper4android works fine on YouTube and all platforms. Moreover, it eliminates the problem of voice reduction when forwarding videos.
Tested PE PLUS (A10) and PE (A11) OFFİCİAL
Before you start installing the Sound Mode, install the SELINUX PERMİSSİVE file with MAGİSK and restart the device.
FOLLOW THE PROCEDURES IN THE ORDER
1. Install the Viper4Android FX zip file with Magisk and
Open the Viper4Android FX application and install the driver and restart.
2a. Install the Audio Modification Library file with Magisk.
2b. Install the Audio Compatibility Patch file with Magisk. ---> Options will be as below.
Volume UP - Volume UP - Volume DOWN - Volume DOWN - Volume DOWN
Restart the device.
3. Open the Viper4Android FX application and activate LEGACY MOD in settings.
DONE.

First of all i want to thank you for the clear and detailed guide...
i have few questions tho, is there any way to install without switching SELINUX to permissive?? my concern here are the security issues
also can i add ainur narsil along with V4a, or is it even worth it?! if yes then what the installation process would be??
thank you in advance!

Unfortunately viper doesn't work properly without selinux permissive.
You can try different sound modes. however, problems occurred when I tried it on pe +. Also I don't think an extra sound mod will be needed after making good adjustments with the viper.

Somehow v4a works fine with selinux enforcing on my xz premium, less headache for me
This is a guide to install mods for OP6/6T that achieve a dual speaker setup that's like the device has stereo-like speakers. I have helped many OP6 and 6T users to achieve this.
Custom ROMs that work with this mod (TESTED):
Stock Oxygen OS
AOSP Extended
ArrowOS (OP6 only)
CrDroid
Evolution X
KangOS
Pixel Experience
PixenOS (EOL)
SyberiaOS
Disclaimer:
*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:
There are issues with the SElinux manager installation and setting SElinux to permissive in my experience. There are alternatives and modules that can be trusted. I have provided links that I have tested and the best module that sets SElinux is the SElinux permissive module. There are SElinux manager modules, but they don't consistently work or install. Like V1.0 doesn't work, try V1.0.5 or vice versa.
IMPORTANT:
Old:
Setting SElinux can have security issues noted by @topjohnwu, so install this mod at your own risk.
Unfortunately, I have not found any method that installs Dolby atmos with SElinux Enforcing and all mods from reiryuki don't work on 6T (OOS 10.3.8). You can try yourself, but backup beforehand as it causes bootloop.
Any other method I found re-uses repey6 and installs it wrong (without setting SElinux)
The alternative module I have found is Viper4Android and can be installed with SElinux Enforcing
New:
Dolby Digital Plus now has released a new version that works with SElinux Enforcing.
Viper4Android is outdated sadly. But There' Viper4Android RePackaged
Methods:
The method works on OOS work on Custom ROMs as well
Download the files required from the links provided and choose Dolby or Viper
Install dual speaker mod and reboot
The OP6 will have many versions that don't install after rebooting so repeat this step until you've installed a version successfully V10 works in my experience. For the Oneplus 6T V3 works.
3. Test it to see if it works and check if it has installed in magisk modules
Dolby Digital Plus Method:
OLD:
Install Dolby digital plus and reboot.
Test it to see if it works and check if it has installed in magisk modules
Install SELinux permissive to set SELinux to permissive and reboot. You need to set SELinux to permissive to make the Dolby mod work properly.
Go into magisk modules to check if SELinux permissive module is installed. If it wasn't installed try another module like SElinux manager 1.0 or 1.0.5 if one of them didn't work, try 1.0 vice versa or the SElinux changer APK. Reboot and check in magisk modules again.
Install audio modification library, reboot, and done.
NEW:
Install Dolby digital plus and reboot.
Test it to see if it works and check if it has installed in magisk modules
Install audio modification library, reboot, and done.
Fix for Dolby:
The next issue is with Dolby digital plus. If the speakers sound quieter than normal and the app stopped working...
Go into settings, app settings, find Dolby app.
Go into permissions. Turn storage on and off.
Try it again and the issue should be fixed.
Enjoy
There is an alternative to Dolby atmos and it is Viper4Android where SElinux is enforcing as well
Viper4Android Method:
OLD:
With the old V4A module
Once you got dual speaker mod installed
Install Audio Modification Library, reboot and disable it
Install the viper4Android module.
If a new version of viper4Android module is available, install that
Reboot.
Open the app and grant root
Install drivers in the app and it will reboot automatically
If u want to have DDC, kernel and preset files look at the DDC, kernel and preset files manual method below
NEW:
With the new V4A Repackaged module
Once you got dual speaker mod installed
Install Audio Modification Library, reboot and disable it
Download and extract the guide setup or the other .zip file attached below on your device
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.
DDC, kernel and preset files manual method
Download and extract all the V4A files or just the file for this guide setup I attached below. You need the DDC, Kernel and Preset folders. Copy all the folders!
In Internal Storage: Copy and paste the folders into (Android -> data -> com.pittvandewitt.viperfx -> files), this would replace each folder.
Now go into magisk manager, go into modules and enable AML. Reboot
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 in settings but it is on by default.
Choose at your heart's desire if you downloaded all the V4A kernels.
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
Note: 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 add the preset (profiles). BUT U SHOULD HAVE ALL THE DDC AND KERNEL FILES FOR THE PRESETS TO WORK PROPERLY
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 TWRP, -> 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 and turn on legacy mode. This should make the effect stay on, even though this should be on anyways.
New Update V4A
Also, for new users if u connect your earphones like via headphone jack, USB-C or Bluetooth. You can tweak those as well than just your SPEAKERS! BUT some earphones can be damaged as well, so tweak at your own risk.
After much tweaking myself. I think I have made my speakers much better and achieved almost stereo speakers for my 6T.
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 DAMAGING 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

This works like a charm, everything you said if followed then you should have no issues at all. Its a great guide and very helpful. Thanks mate
Update Log:
5/06/2021 - I have attached the presets which I use for my speakers and earphones.
If u have already installed V4A without the presets follow this new method.
Download the .zip file of my attached presets or all the 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
2/11/2022 - Updated XDA thread as new Viper4Android Repackaged was found and supports Android 13
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.
I got this install failed during viper4android module installation. after reboot, it asked me to update and install the module, but after that i still don't see the app to grant permission. I'm using crDroid on a Samsung a22. audiofx is disabled

Well your device is a Samsung which may act differently to the Viper4Android installation. This guide is for OnePlus 6/6t. The app should still work, but not sure for your device

Love the presets! Mainly use the viper-DDC stuff I have had DDP &V4A installed for quite some time on a HD1925 OnePLus 7tpro McLaren with LOS17.1,
I am also going to try the Dolby fix, normally when I am using an app like tiktok or something like that & get a phone call it kills DDP 7.3 and I normally have just been rebooting. If the fix works ill create a tasker profile to automatically reset it!
Great tutorial! Thank you for the time
Dolby fix works perfectly! Thank you for that tip!

I wouldn't recommend using the dolby and I have said why. "Setting SElinux can have security issues noted by @topjohnwu, so install this mod at your own risk." Here's an article: https://www.techrepublic.com/article/why-its-time-to-stop-setting-selinux-to-permissive-or-disabled/
In the long term, V4A is the better choice especially when SElinux doesn't really affect it and it works on SElinux Enforcing. Dolby kinda works on SElinux Enforcing but enjoy dealing with multiple crashes

Not sure why but I have never had to set Selinux to permissive but Dolby still works, thank you for the warning though, I would not have used if I had to
I do not deal with multiple crashes in fact, just when using tiktok and get a call I need to turn V4A off and on & Dolby I have to apply the above fix which I have set a Tasker autoinput profile now to do both automatically
Everything is okay with v4a but Second speaker turns off at max volume. Probably i should decrease default speaker gain(

Which device do u have? The 6T works flawlessly not sure for the OP6. Tbh I have attached profiles in the guide_setup .zip file and the profiles in there work fine
Followed this guide for my OP6 running LOS 19.1. I used v10 stereo mod with latest Dolby Digital Plus and AML modules. It works but it's not true stereo. When playing a stereo content, left channel is coming to both earpiece + loudspeaker and right channel is coming to ear piece alone. Tested using stereo test videos on YouTube. Is there anything I'm missing here? Probably due to LOS or Android 12. Left channel output seems to be a problem.

Ofc it's not true stereo as the manufacturer will have to do that. But it's "stereo like" so u have 2 speakers instead of one like newer phones that have stereo speakers. But it's better than not having it
New Update
Guide has been updated for Android 13 and using the new Viper4Android Repackaged module
Hey all,
some tips on getting ViPER4Android to work on your S21 / OneUI 3.1.
Disable Sound Alive via ADB or a root solution of your choice (not sure if this is actually needed, but I recommend to do so). You can use the Dolby Atmos Magisk module by repey6 if you still want Atmos.
Install the Audio Modification Library module from Magisk
Install the ViPER4Android module from Magisk
Go to /sdcard/ViPER4Android and install the apk that the Magisk module has put there
Open ViPER4Android, grant root access and let the driver install (your phone will reboot immediately)
After the reboot, go to Magisk and disable the Audio Modication Library and reboot again
After the reboot, open ViPER4Android and install the driver again
After the reboot, re-enable Audio Modification Library and once again... reboot.
Now go to ViPER4Android settings and enable Legacy mode (you will have an abnormal driver status otherwise).
You should be good now.
You do not need to set selinux to permissive. Yep, 4 reboots to make it work, but hey - good sound!
Works with Ainur and Dolby Atmos as long as you use AML. I recommend to do this installation procedure after you have installed the other sound mods.
Note: If you only want to use ViPER, no other sound mods, it might be possible to just perform step 1, 3, 4, 5 and 9 (not tested). If not, do all steps.
If it still does not work you can try to add the Audio Compatibility Patch module. There is also another thread here, providing useful information.
Best regards,
lartsch
