Hello.
So I installed a custom recovery, flashed lollipop fw and installed supersu.
Today I was trying to install Viper4Android but, unfortunately, it does not work.
I also installed the drm restore patch (audio clear + is working).
Is there any fix ? Is Viper working for someone here?
Thanks in advance.
Interested too, have a z3c too and have found a few threads describing the installation in 2 steps, flashing via recovery and installing an .apk but nothing specific for z3c.
will update this thread once I have a full nandroid backup and am ready to play around.
I was in the same situation as you guys and couldn't live without V4A.
You/we forgot 1 step
You need to set SELinux mode to permissive and then install V4A driver:
Use this simple app:
https://play.google.com/store/apps/details?id=com.mrbimc.selinux
Amy more advice? Tried that, then set it back, yet viper doesn't seem to be getting used although the driver is installed, where do I select viper as the processor for audio?

You don't, I was also looking for that for a while, but PowerAmp picks that up automatically and so I guess the entire OS

Nope, seems like they removed it from the store
I've had a backup with TItaniumBackup but I was just curious what happened there...
Did as Dsteppa sayed. Worked for 10 sec. closed music app and viper and start again. Same thing. Btw I have force enable V4A. Then i went to viper settings and changed FX compatible mode to compatible and restart phone. Works perfectly! Thanks so much!
The solution is disable or froze "Sound Enhancement" app, and that's all, V4A is going to work fine without need of change the option to "Compatible Mode".

Thank i try now
MrPingle
Also make sure that Equalizer (in settings, not Viper) is set to Off mode.
I try to install V4A (through Apk) but when i install the drivers, a message says: "Driver install failed: the busybox installation on you device does not work... etc."
I have just installed the last version of busybox in /system/xbin and set Selinux permissive.
How can i resolve it?
I get root with Kingroot e after change binaries to Supersu's binaries.

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..

Has anyone actually got V4A to work on T719 (EVR)? No matter what version of V4A I install nothing works. I've tried different audio_effect.conf's, system / user setups, busybox (no idea how to set it up), fash from TWRP, Flashfire, Freeze SoundAlive and Adaptsound, delete SoundAlive and Adaptsound. But, NOTHING ACTUALLY WORKS! Can anyone help me to get V4A up and running on a T719 (EVR) with the phone still working?
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

Do you still have that apk lying around? XDA Labs does not appear to be working ATM.

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.

Hello, firstly sorry for bad english. My device is a Samsung s3 mini running 4.2.2 touchwiz. I'm trying to make that old phone my music player with viper4android. I installed latest magisk and magisk manager. Whenever I install a module installation happens without any issues. But after a reboot I can't see any changes that module makes. For example after installing viper4android it seems like it's installed on magisk manager but there aren't a app on app drawer, I tried few a more modules such as audio library patch etc. they all behave same. Looks like installed but has no effect over system. Secondly when I try to uninstall any of the modules it won't uninstall. I uninstall, reboot and it's still there. What can I do to solve my problem?
