How did you install the viper4android via apk or you flashed from recovery?

In order to install ViPER4Android, you'll need your system to be properly rooted, BusyBox must be installed, and SELinux Mode must be "Permissive".
I recommend this BusyBox installer, and you can get SELinux Mode Changer from here.
Then, after everything is properly set up, you must also disable your ROM (e.g. CyanogenMod-based ROMs' AudioFX)and/or player (e.g. Poweramp's equalizer)'s built-in equalizer, and switch ViPER4Android's FX Compatible mode from "Normal" to "Compatible".

I was able to make V4A work on my Moto X 2014 with a fix.
If you do not have Busybox or permissive SELinux, follow the instructions our mate's posted above:

After Busybox installed and SELinux on permissive, you flash the Viper zip and install the driver. Right after that you open a root enabled file manager and find system>vendor>etc. You'll see an audio_effects.conf.
(I suggest making a safe copy of this file).
Rename the original audio_effects.conf to audio_effects.bak.
Save and reboot. Now try using v4a again.

Was this procedure required for V4A to work on your Victara? Mine worked in every ROM I tested (all Marshmallow-based) by following the steps you quoted.

Yes. I was only able to enjoy v4a after this procedure.
It's worth pointing out that V4A is going to F up your Moto Voice
Popping into this thread real quick to provide some info,
Using compatibility mode with V4A is bad news, causes extra battery drain and problems with some apps.
For every single rom and device I've used 5.0+ I've followed the same procedure to install V4A, without using compatibility mode, without having to delete a file every time, etc.
Flash the "lolliviper" zip attached to this OP.
Followed by the "Build.Prop-Tweaks" and "Soundfix-LibFiles" attached to this post.
You'll also need a way of setting selinux to permissive after every boot if you're using CM or something else with selinux set to enforced. Something like SELinuxModeChanger available here will work.
If you don't have busybox installed, V4A will tell you and help you install it.
The V4A version included in the "lolliviper" zip is not the newest , you'll need to "Check Update" via the 3 dot menu and install the latest apk.
After all this, install the driver via the V4A app, reboot, and you're golden.

Didn't know that. I was only able to set v4a on a custom ROM, so that ship was long gone hahaha
it just stops working?

Actually it still "works" because it detects your launch phrase, but after that, half of the time it just hangs without hearing your command. Sometimes it'll randomly work, but it was too much of a botch to keep it that way. I've now resorted to Noozxoide Pro: it's still a system-wide mod with modes for headset, speaker and BT, but it's installed as a "standard" app, it doesn't mess with your system and it sounds boss!
I ran across this link on a similar search on the google machine, and it made V4A installation a breeze. No manual messing with kernel settings and whatnot: http://forum.xda-developers.com/android/software/viperaudio-viperatmos-3-8-sq-driver-t3289075
Battery life has been fine running this for about a week. I don't use Moto Voice so can't comment on that.
THANKS

Thanks a lot, I was already discouraged, tried several versions of viper, on diferent roms, this was the only solution, but is necessary to remember that for this file to appear in the folder, you need to open the application and save a profile, even if empty, without it you can not find the file audio_effects
If u root ur device using magisk, u can install viper magisk module...it works fine on android 6.0 with selinux enforcing..

I would also advise against this mod. Although I have used ARISE in my previous phones, it crashes on ZMPM1. SElinux is set to permissive and all other audio mods were uninstalled. Still it crashed and rebooted to recovery everytime.
Since it overwrites many system files, it has also probably interfered with apps some of which become unresponsive. I will have to flash TWRP V327 again since it is almost impossible to isolate the issues.

V4A (Magisk Module) worked for me without touching the se policy or installing busy box. However, after trying out this mod and subsequently deleting it I find V4A asking for busy box installation and then driver installation error. I will try afresh after flashing v327 through TWRP again

Thanks. Can't systemless busybox + init.d injector work? You can try perhaps for v4a to get working.
This audio mod and ainur sauron change the system partition hence i thought it would be better to ask someone who already got it working.

Tried it but something is breaking driver installation. I neither have the expertise nor the the patience to check cfg files in audio policy or elsewhere. Too many system overwrites. Flashing stock seems to be the way to go.
Another curious development which may or may not be related -
1) Safety Net check now fails.
2) Making a TWRP backup of the installed ROM fails at System Image.

Uh oh. Better to stay away from this mod then.
I've been using viper4android xHiFi, it works perfectly and the audio quality is exactly the way I want it to be.

You dont need an app.... Because
Arise modifies the system files...its not an effect that applies on top of streaming music...
Also, Arise has different music profiles/presents....you can try them also(avaliable in the same aroma installation)
..Feel the difference..
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
If anyone has any issues with this guide. Post a message and I'll get back to you

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
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
Thanks for sharing
Thanks for that, I was having a tough time installing it on the tab s7+ maybe this will work...
