So I mainly use my phone as an on-the-go MP3 player and want to use V4A as my audio driver, but I cannot seem to get it to work. I tried when the phone initially came out, but gave up since I figured maybe it was a compatibility issue, but decided to give it another shot tonight.
Upon installation of the latest version (2.5.05), nothing worked. I followed the troubleshooting on the website and have gotten nowhere. When I check the driver status, I get the following log:
Driver Version: 2.5.0.4
NEON Enabled: No
Enabled: No
Status: Abnormal
Audio Format: Unsupported (I'm guessing because nothing it player at the moment)
Processing: No
Sampling Rate: 0

I'm not exactly sure where to go from here.
SELinux needed to be in permissive mode for me.
I used SELinuxModeChanger from F-Droid.

Hello all ,
Update August 7th 2018.
Wirh recent versions of v4a , theres no need to use this method unless you tried the latest official v4a magisk module or zip and it didn't work, current v4a magaik module works perfectly with latest 5.0.4 stable rom and all betas from oos, and moat if not all 8.1 custom roms
The following is not necessary as of August 7th 2018, unless you tried official zip or module and faced issues:
a lot are asking and searching for a way to make V4A work on OOS Oreo, sadly so far most posible ways either require a lot work or setting Linux to permissive wich breaks saftynet.
the bad news is this method also Sets SELinun to Permissive but it's simulated through Magisk so it doesn't break SafetyNet...
Method:
1- download and install busybox (make sure it's installed) i personally use a pro version, some of the ones on playstore wont install so try until you find a working one.
2- Update , using the latest V4A 2.5+ version by ahrion you don't need to use Magisk SELinux Permissive Scrip because he added to his module a detection script that will detect OOS Oreo and set permissive automatically
Download and flash LatestViPER4Android FX 2.5.0.5 [Unity/AML] by @ahrion
3-reboot and have fun
if the above doesn't work
2a- download and install Magisk SELinux Permissive Script module v1.1 (all thanks to @Jman420 ) and reboot.
3a- download ViPER4Android FX 2.3.4.0 (Super High Quality) v2.1
4a- install V4A module downloaded in the past step then reboot.
5a- now V4A should be perfectly working...and It Passes SafetyNet
Screens Attached.
Excellent job, works like a charm with oos 5.
Big thx!
is bluetooth also working on this method?
I have tried your method but V4A is still not working. Thanks anyway

make sure Busybox app is installed and open it and inside it click install, the app itself has to install somethings... there's no reason for it not to work, if you've done that and it's not working please share a screen of v4a driver status while playing music .
It didn't worked for me either
Works fine!

It's not a big deal. I will wait for stable release. Thank you for the help anyways.
I flash viper4arise (Deuteronomy 2.4), it contains viper4android 2.5.0.5. To get it to work with selinux enforcing I used to install the magisk module Allow audio server on Nougat (https://forum.xda-developers.com/on...sk-modules-oneplus-3t-t3548446/post70819460). On Oreo I doesn't work anymore. Now I set selinux to permissive in developer settings in viper. It'll last till you reboot, then selinux is enforcing again.

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.

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.

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.

my bad for not paying attention
but i'm a bit reluctant to downgrade my magisk
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...
I've tried installing the driver multiple times and can't seem to make it work at all. The only method I've not been able to accomplish is renaming audio_effects.conf to audio_effects.conf.bak as has been recommended for other phones. For some reason, this file will not rename.
it would seem the file is set to be unwritable (I'm not familiar with linux permissions like this, so maybe that can be fixed somehow?). At the very least, Solid Explorer isn't able to do the job, and can't change the rw perms either, as the operation just fails. (I have got selinuxmodechanger changed to permissive and after reboot, but no change here either)
Any other ideas?
Well, for anyone else wanting to know how to make this work, follow this guide here: https://thedroidarena.com/install-viper4android-android-10-q/
Don't use the magisk module for V4A, it doesn't work.
Works great for me now!
I'm using it it works perfect but you have to use the new version not the older one

I saw that, didn't really know what it did. I'll check it out.
Nothing in JamesDSP is doing anything for me on Speakers, Headphones, or Bluetooth. I think that this may beacause of my failed install of V4A rootless (might work if I had the APK?). Any ideas if this is the problem? If It is, do you know how I might uninstall V4A?
If rooted, try installing latest V4A directly from here (https://labs.xda-developers.com/store/app/com.pittvandewitt.viperfx) rather than via Magisk.
I prefer older V4A versions, having tried above.
My preferred V4A is 2.5.0.5 (found in App folder in following .zip from here: https://androidfilehost.com/?fid=673368273298920860)
1. Ensure on latest BusyBox.
2. Install latest V4A from Magisk & download driver, device will auto-restart.
3. Uninstall this latest V4A (don't delete data or cache).
4. Install V4A 2.5.0.5 .apk from above link. Don't open app yet.
5. From Magisk, install Audio Modification Library (choose relevant options). Restart device.
6. Additionally, Magisk install Audio Compatibility Patch. Restart device.
7. Ensure V4A settings FX compatible mode option = Normal.
(Don't optmise V4A in battery settings).
Noticeable improvement in speaker volume (I don't play over BT or headphones, so cannot comment).

I uninstalled everythingg I had installed up to that point (everything I could at least), and followed the instructions step by step. Still getting abnormal in the V4A app (at least the app looks cooler now : P). I really don't know what is going on at this point. I might just reset the whole phone and follow your instructions again. I will report back when I get around to that.
Ok, I decided to play around a little before trying a reset; and I installed Viper 4 Android legacy with the APK from the zip you gave me, and it now says audio format supported! Yay! It just says "Processing: no" now. I have a feeling that I have something setup wrong. Any ideas?
Edit: Grammer
You managed to install driver v.2.5.0.5 or latest v4a?
Processing should change to "Yes" whilst audio is playing (music player/ YouTube/ system sounds etc).
Streaming music can be hit & miss; set up Audio Compatibility Patch correctly (via Magisk).

I installed driver version 2.5.0.4 with the APK you pointed me towards in the .zip/viperfx/app folder.
I will reinstall the audio conpatibily patch. What options should I choose in the patch?
Edit: I did not install the driver *with* the APK, but alongside it. I installed the driver via ViperFX Legacy in Magisk.
Try the ACP if V4A not working for streaming music apps.
I selected following:
- Skip audio_policy patching? = NO
- Skip notification_helper remover? = YES
- Skip usb policy patching for usb dacs? = NO
- Use lib workaround? = NO

That's fine, as long as V4A driver is enabled/ status normal/ format supported/ and it is processing during audio play.

It still isn't processing audio : (. I have tried resetting and following your instructions again. The only way I am able to get it to stop displaying "Status: Abnormal" is by installing Viper4Android FX Legacy in the new driver mode with the user app, then installing the Audio Modification and compatibility patch, then restarting and installing the APK you gave me. Even with all that, it will not recognize audio being played (it displays "Processing: No" when audio is very clearly playing and I have effects enabled). I am now considering switching to LineageOS (I would be there already if it wasn't for the fingerprint sensor driver being broken).
Edit: Do you think switching kernels would change anything?
Edit 2: I noticed a toast notification from V4A on startup saying "A running program has requested Android to disable audio effects, so V4A will be temporarily disabled."
I am thinking that maybe the stock Dirac audio processing might be interfering with V4A somehow. Is there anyway to get Viper to ignore requests to disable?
Well, Lineage didn't fix anything (No matter what I did, V4A would not stop displaying abnormal). Took me a little while to get back to stock, but the latest version of V4A is working, but only for the first 30 seconds after reboot before giving me the previously mentioned toast notification. I have removed all apps that are even remotely audio processing related, but still have this problem. Anybody else had something similar? If you did, how did you fix it?
(Also, special thanks to elmor0 for all of your help getting me this far I'm so close)
Edit: Holy shiz it's working! I used the method described in my previous post, but with the added step of uninstalling and reinstalling audio modification library after the last reboot. Again thank you all for your help! And I really hope this helps someone!

hi
I'm having the same problem for months now
I hear it needs SE Linux to be permissive for V4A to work properly
I had no success on getting that SE Linux to turn Permissive unfortunately
long story short , I found myself here
can you please give me a step by step on how you got V4A to work , that is off course if its still working for you man
I'm at the end of my rope here , any guidance would appreciated ,
Thanx

I ended up refllashing with Lineage and installing this: https://forum.xda-developers.com/t/app-fix-100-working-viper4android-for-android-11-devices.4213647/
That version has worked flawlessly for me for Android 10 and 11.
Good luck!
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

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

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
I have installed the latest build 9.16, but it seems DASH charge and face unlock is not available, does anyone knows what's going on???

Wrong thread. Idk what you're going on about. What 9.16 build? You can't just go one any thread and post issues. Especially with no context
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
