Please note, this requires SELinux Permissive (included init.d script/instructions for PHH). It will not work on Enforcing, even with supolicy (I've tried. If anyone has an idea how to get it working with "soundserver" and setting supolicy "read write execute", please let me know)
Setting SELinux to Permissive is a security risk.
ViPER4Android for Mate 9
Slightly modified guitardedhero script.
Contains "Kernel" and "Profile" for V4A from auras76 kang rom
Note:
The following files are backed up automatically so you can easily revert with the removal script:
/system/lib/soundfx/libeffectproxy.so -> /system/lib/soundfx/libeffectproxy.so.bak
/system/etc/audio_effects.conf -> /system/etc/audio_effects.conf.bak
/vendor/etc/audio_effects.conf -> /vendor/etc/audio_effects.conf.bak
If those .bak files are not found the removal script won't run (to prevent running it without V4A installed, it would simply just remove the files leaving you with no files at all.)
It does not edit audio_policy.conf as it doesn't have the deep_buffer section in it, so no point in having it edited.
Requirements:
SuperRoot/SuperSU (No verity is probably needed as we're modifying both /system and /vendor)
A way to set SELinux to Permissive (SuperSU init.d/phh 'su --init' or SELinuxToggler, see 'Alternative'.)
If you're on Magisk use the V4A module instead
For SuperSU
If you use the one posted above
Simply flash the zip in TWRP and you should be good to go. It copies the 00selinux script directly to /system/etc/init.d/ and runs at boot so you'll have SELinux set to Permissive after flashing.
For PHH su
Flash the zip in TWRP, boot up fully.
Now open a terminal and issue the command
Code:
su --init /system/etc/init.d/00selinux
Then reboot.
To remove the phh init use 'su --init !/system/etc/init.d/00selinux'.
For Magisk
Search for Viper4Android in the Downloads section in Magisk Manager, it's a module so no need to download anything in this thread
Alternative:
(You still need root for this but no init script.)

@ante0 bro thanks for porting it... have a question, we have to mount system in terminal for writting in system partition,,, can i use init to mount system rw for all time so that i dont need to give command everytime

Yes, if you use supersu, make a script in /system/etc/init.d/
Code:
#!/system/bin/sh
mount -o rw,remount /system
Make sure it runs after any other scripts if they remount system to read only. Scripts are loaded in order, so name it accordingly.
If you use phh, place script where you want and from a terminal
Code:
su --init /path/to/script
I wanna put all this in my Kernel... Or boot.img...
I have root in my kernel using phh superuser... I dont want to add anything in system by myself, i want that a zip should do it... Will be best if kernel did all this... In MM, we dont need to do rw ourself, in N we needed...
Also, am not a dev, just a pro member, know how to edit and understand commands etc...
May I ask whats the difference between this and Viper4Arise.

By flashing superuser r275 on stock boot, we can have root but on that root, titanium like apps didnot work :/

It's just a skin difference. Viper4Arise is themed by an arise member. The only difference is the theme.

Will V4A work on P9, P9 plus and P9 lite if we flash those files?

I don't know. But I don't see why it wouldn't.
Backup system and try.
You'll have to use the phh init script though as I don't think supersu works with P9 on emui5?
Edit: actually, if your audio_effects.conf file is not in /system/etc/ or /vendor/etc/ the script needs to be modified. And if your audio_policy.conf contains the deep_buffer section.

assuming everything else but the driver is installed,
simply download Viper4android_2.5.0.5_mate9.zip, extract.
go to customize/lib, rename libv4a_fx_jb_NEON.so to libv4a_fx_jb_ics.so
copy it to your phone.
Use a root file manager and copy and paste to /system/lib/soundfx/libv4a_fx_jb_ics.so.
And set permissions of that file to 0644 (RW-R--R--).
Then reboot and open up viper4android again and see if still complains.
If it doesn't, go to "hamburger" menu in V4A and tap on Driver Status, it should say Status: Normal. If it says abnormal something else is wrong.

@ante0, I just wanted to give you a quick heads up...
There's a new app (currently being beta tested) that will supercede/replace The SELinux Toggler....
It's a new app called "The SELinux Switch". Though, it will look like "The SELinux Toggler" but, I had to recreate, pretty much, the whole app.
The reason i had to do this is, primarily, to completely sever it from the older package name (or Installation Directory) that was also being used by the "SELinuxModeChanger" app.
I also had made some minor enhancements and a few compatibility improvements but, there's still some more improvements to be made.
In addition, the app has been passing the beta testing extremely well (thankfully after about 6 +/- months into it) and it should be released soon but, when the app has completed the beta testing and, ready for its debut, it will be released under a whole new thread.
Thank you all for your time, understanding and, especially, your support for my development.
Please let me know if you have any questions or concerns.

PLEASE NOTE: I welcome any member to help with further valuable information/clarification for any of my posts.
Has anybody used the ARISE aroma installer (twrp flashable zip)? I've used it on a few other devices, coming to the M9 from a Le Pro 3 and it works nice and easy and patches selinux permanently. It seems the way Huawei does things is much different though, so I'd be suprised if it works as easily as on other phones.
In the end, it's just installing 2.5.0.5 anyway with a few other tweaks and a whole bunch of IRS response profiles. So that part's not very different.
Just a quick heads-up @ante0...
The SELinux Toggler has now Officially been Discontinued for the launching of the new app...

Deprecated - Use the New ViPER4Android v2.7:
GO TO THE THREAD LINKED ABOVE. You don't need to flash any zips. Just install it as a regular apk, allow it to install the drivers, and you're good to go.
For magisk users: I made a zip on the repo that includes the original vdc's and my profile converter (will convert your old profiles to the new and better format).
For rootless users: I made a zip to install drivers and such
Zips can be found here
ALL SUPPORT QUESTIONS FOR 2.7 SHOULD BE AT THE THREAD ABOVE.
This is ViPER4Android FX and Xhifi Unity installers
These installers utilize my Unified installer that can install on Magisk OR System if Magisk is not detected (with Pixel support).

Special Instructions:
If you already know which original v4a you want to use, just add 'old' for 2.3.4.0, 'mid' for 2.4.0.1, 'new' for 2.5.0.5, or 'mat' for material to the zipname prior to flashing.
If you already know if you want it installed as a user or system app, add "uapp" for user app or "sapp" to system app to zipname.
If you already know if you want to apply the libstdc++.so lib workaround, add "lib" or "nlib" to zipname (note that there are some devices that are already known to require it and so they'll apply workaround regardless of choice)
If you already know if your device/rom requires the v4a open/close/fc audioserver workaround, add "ocw" to zipname. Otherwise, add "nocw" to zipname
To skip volkeys (if your device isn't compatible with them), add "novk" to the zipname. Note that if you don't specify the above, defaults will be applied which are: sapp, new
Make sure there are no spaces in the zipname

Hi, tried your two modules you've posted on my Nexus 6P stock ROM. March update. Both causing bootloop and using the uninstaller provided doesn't help. Have to use mount Magisk then go to file explorer in TWRP recovery and delete the modules from Magisk folder.

Hmm. This is probably a kernel or magisk limitation with your rom. Are you running 11.6? Try to run it without the deep_buffer Remover because this is probably what bootloops your phone. It's only necessary when you've NEED it, otherwise it may cause adverse effects. Just install V4A and see if it works.
Currently magisk still has limited boot.img compatibility which causes so.e mods to not work properly or bootloops when it's not the mod itself.

Magisk limitation. @topjohnwu is always improving magisk. I do recommend may e trying another kernel for your device which may help compatibility.
Gave this module a go, and: it's a no go... Will not boot on my Nexus 6 running Vanilla ROM 7.1.1_r26, Franco Kernel r65 and Magisk v.11.6 - MagiskSU.
After flashing uninstaller the device still doesn't boot. Had to manually remove audmodlib from /magisk in TWRP to make it boot again. And it's in audmodlib the problem is. I did a quick test where I removed audmodlib after installation (kept v4afx in place) and it booted right up (with a non-functioning module, obviously).
Attaching installation and uninstallation recovery logs. Unfortunately I'm not at a computer with ADB, otherwise I would have captured a logcat of boot for you. Maybe later...

The only real thing in audmodlib is could be is service.sh or system.prop otherwise it would be the vendor file, which would mean that for some reason 11.6 is bugged for vendor file mounting. Try installing and remove those ONLY and and see if it fixes it.
If that fixes it then it's one of those two. And if you're cool can you see which one it is exactly.

There has been an issue with vendor mounting in Magisk, but I believe that was for devices with separate vendor partitions (Nexus 6P, Nexus 5X, etc). I haven't seen any commits on GitHub about it though (although I haven't been keeping that close attention), so I don't know if it's been fixed.
I did find the culprit though: it's system.prop. With that file removed from /magisk/audmodlib my device booted up just fine.

I will remove it with next release. Thank you man. This **** only started happening with 11.6. this was the reason Atmos was boot looping as well so I removed system.prop in Atmos.
Can you do me a favor and remove a few lines to see if it's just the specific lines? I think that certain lines don't play nice with your phone.
Remove the first part, low power audio tweaks, reboot and see if it works. If it doesn't then that's the culprit. If not then remove the first two on the other audio tweaks.

AS OF 03/07/2018
Support and development of this module have been discontinued.
A replacement module can be found here : https://forum.xda-developers.com/apps/magisk/module-magisk-selinux-manager-t3760042
This is a very simple module that installs a post-fs-data.sh script which enables SELinux Permissive Mode. This is useful for certain audio mods and removes the need to understand Magisk's file system & boot logic. No need to create your own scripts, just flash and forget.
I have only tested this on my Verizon HTC 10, but this module is so simple and generic that it should work on any Android device with SELinux.
This module has been tested on and is compatible with Magisk v11.6-15.2.
Disclaimer & Recommendations: This module should be used as a last resort only if appropriate SELinux Permissions can not be generated and injected into the SELinux Policy using selinux-inject, supolicy or magiskpolicy. Putting your device into Permissive Mode will essentially disable all of the operating system level security built into Android and allow any app in any context to do whatever it wants. Actions requiring root access will still trigger your SU Manager App, but all apps have elevated privileges due to permissive and may be able to take malicious actions on your device without needing root access. If you find that this module fixes issues you are experiencing with an app I recommend contacting the app developer and trying to work with them to isolate the necessary SELinux Permissions and have them injected into the SELinux Policy at startup.
Here is a discussion of some of concerns to consider when running your device in Permissive Mode : https://forum.xda-developers.com/general/general/discussion-root-selinux-risks-t3607295
Github Repo : https://github.com/Jman420/magisk-permissive-script
Change Log :
v1.0 - Initial Release
v1.1 - Update to Module Template v1400
v1.2 - Update to Module Template v1500

Regarding your other post mentioning Xposed (which I'm not quoting cause it's a mess). I'm running on Nougat so I can't use Xposed and haven't tested with it. If you give me more details I can try to determine what the issue is. Logs, error messages, symptoms would all be helpful.

I don't understand why this mod is usefull. In the latest version of magisk, there is a semi enforce/permissive linux bypass. The system thinks it's enforced, but in reality is permissive. Or maybe I didn't fully understand it?
its working with s5neo?

I agree that Magisk hides the actual SELinux Mode in such a way that if Magisk Hide is enabled the 'getenforce' command always returns 'Enforcing'. But if you do not run the 'setenforce 0' command the SELinux mode will still be set to 'Enforcing' rather than 'Permissive'. This script puts the SELinux mode into 'Permissive' at startup. Magisk Hide will still hide the fact that you are in Permissive Mode, which I believe is the 'pseudo permissive' mode that Magisk describes. But I can not find any settings or commands within Magisk that enable Permissive Mode.

It's just a shell script, the source is in the zip file. This is really helpful and is the direction I want to take this project. Permissive Mode is great in that it gets the Apps/Mods that we want to run to work, but I consider it the equivalent of using a sledgehammer to hammer in a finishing nail. I would much rather be able to grant the specific permissions that each App needs rather than enable all permissions for all apps (which is what permissive mode does).
I plan on trying to develop an App which will assist in managing and generating a script which uses 'supolicy' to inject individual SELinux Policy Permissions. I had planned on using the Dolby Atmos LePro3 build as a guinea pig to try to isolate which permissions it needs and put together the supolicy command for them. I've hit a bit of a roadblock in verifying my supolicy command due to the format that the SELinux Policy is stored in on the device. I've found a project called sedump (https://ge0n0sis.github.io/posts/2015/12/exploring-androids-selinux-kernel-policy/) which claims to deserialize the Binary SELinux Policy to a readable format, but I can't seem to get it to work... the process seems to complete, but it generates an empty file... If anyone has experience with SELinux I'd really appreciate any feedback.

Dunno, I've only got an HTC 10 for testing. Give it a shot, if it doesn't work just uninstall the Magisk Package. Remember to disable Magisk Hide if you are testing to make sure it actually put your phone into Permissive Mode by using the 'getenforce' command.
It works for oneplus 3t on freedom OS rom.

Should be able to install it through Magisk Manager or TWRP. Let me know if you have problems.

I don't understand why this mod is usefull. In the latest version of magisk, there is a semi enforce/permissive linux bypass. The system thinks it's enforced, but in reality is permissive. Or maybe I didn't fully understand it?

Now, I have magisk 11.6 on EMUI marshmallows V4A driver was abnormal because Enforcing selinux. Same happened with SuperSU 2.79. When I changed to permissive mode using terminal emulato/kernerl aduitor init.d script emulator/su.d SuperSU script, V4A driver was normal and it was processing. I like Magisk a lot because of its xposed like modules. Now using jman420's permissive magisk module.

Without this module, ARISE is working fine, processing in 48000 on my side, so for V4A I don't think this is necessary, at least on my side.

For ARISE I used to flash permissive script by osm0sis. Otherwise no luck with V4A, AM3D and Dolby.

Strange... Did you enable magisk hide? If not, that is the reason.

Hello all
viper4android refreshes very rarely and can not keep up with nexus / pixels.
I have seen many guides that suggested deleting the configuration file in /etc/audio_effects.conf.
I think it's a horrible thing! in fact, just insert few strings into another file in /vendor/etc/audio_effects.conf
Under libraries sections:
v4a_fx {
path /system/lib/soundfx/libv4a_fx_ics.so
}
Under effects sections:
v4a_standard_fx {
library v4a_fx
uuid 41d3c987-e6cf-11e3-a88a-11aba5d5c51b
}
it is very important that selinux is set to permissive mode.
Open a Shell :
$ su
# setenforce 0
P.S. install busybox first

Good guide but that setenforce 0 command doesn't stick after reboot as far as I know. To get it to stick you should use an app that does it or create a .sh file and add the permissive kernel code to it. Can't remember where the file goes though.

In viper's app there is an option "disable selinux".
You only have to go permissive with magisk and there's an module for it.
With SuperSU you can stay enforced.
Delete musicfx or audiofx and you're good.
Been trying for days to get viper to work,thanks man.works for me

personally I prefer to add two lines of code instead of installing an application that allows another application to work
Right very good guide, but you have to go and live permissive with it. The question is, what's better. If you root anyway ???

Dev,you wouldn't happen to know how to get ATMOS working would you?
I prefer to go permissive as well, besides the fact that I'm always permissive even when I don't have V4A installed.
Also, you don't have to install an app, you just put a permissive script in your init.d(if not using Magisk). For Magisk, you put it in /magisk/.core/service.d/.
I've created my own flashable zips to do this, and since it's Magisk, as long as I don't clean flash, I never have to worry about it. [emoji41]

here we talk about viper. Magisk and company should be treated elsewhere. Just create an init file for selinux.
Not a Magisk module. If you're using Magisk, you can't stick the init.d script in /system/etc/init.d/ since the system won't being using that location IF you're using Magisk. That's why I included both locations just in case someone that's using Magisk came across the post.
Either way, I was still talking about Viper.

I've been using latest Magnum opus on 8.1 without any problems or changes needed to the system. And it works perfectly fine with viper+Dolby config

Maybe you can. Have never had ARISE or Viper work without permissive, on either Magisk or SuperSU.
Not maybe, supersu makes it possible to stay enforced with viper and dolby. With magisk Viper might be possible enforced but dolby will run only permissive with magisk.
Tested so many times.

@snsone are you using android oreo? And if so, how are you doing that?
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.

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...
