I've tried to install this several times and the driver never gets enabled. It asks to reboot in order to install the driver every time I open the app after rebooting the phone. Did you do anything special? What's the secret?

You have to choose viper4android fx.

Thank you all for your replies. Zack helped me figure out the issue. I had installed Audio-Modification-Library module which was preventing A4A installation. Cheers!

Because of this post, I decided to install the Audio Modification Library module to see what it does. Oddly enough, for me, V4A actually started working after enabling this additional module and setting my kernel to permissive. Weird. Glad it's working now though!

lol... nice!

I just had the same issue as a result of upgrading stock MIUI Android 7.1 ROMS on a Xiaomi Mi Max 2.
I solved it by:
1. In Magisk, disabled both Audio Mod Library and Viper4Android --> REBOOTed.
2. In Magisk, ENABLED both Audio Mod Library and Viper4Android. --> REBOOTed.
No driver errors and it works in Speaker and Headphone.
But I'm not getting any Viper Notification in the Shade or the Status.

Did you try Disabling/Enabling the modules in Magisk? I had to do this a few times before it worked. Viper status will report 'Processing: No' until you start playing a music file, then it should change to 'Processing:Yes'.
I was able to get the notification to show up by selecting the first option in Settings>Show Notification.

I've tried just about everything I can think of.

Here's what I don't get. I have 3 devices currently. All running Oreo. Huawei Mate SE, Xiaomi Redmi Note 3 and Ulefone T1. The Redmi Note 3 and Ulefone T1 both have V4A working fine and both kernels are Enforcing. The Huawei no matter how it's set refuses to work.

Cant get Viper to work properly

Hey guys,
since i got my Oneplus 6, i couldnt get viper to work quite right. Most of the time its just shows "Processing: No" till i restart it and after like a hour or device switch it turns off.
I tried:
Copying the Audioeffects.conf from system/etc to vendor/etc
Using Magisk Audio Compability Module
Using Alternate Magisk V4A Module
Using a Magisk Rom with Build-In V4a (currently xXx 2.8)
Disabling Dirac and Services
but nothing worked
thanks for your help

i had the same but then i tried to use the other viper release from magisk and it worked. there is this one called hifi and fx

Try exiting the viper app with the 3 dots top right hand corner. That is what worked for me

Sounds to me like you need to disable the battery optimizations for Viper. It's almost as if your phone is detecting High battery drain and shuts down the app

I'm using the Android p beta and i don't have the problems with viper as i did with oxygen os 5. it's always processing for my headphones, either plugged in or Bluetooth. the only exception is sometimes after receiving a call while listening to music, after the call is over and my music resumes, viper is no longer processing. not every time though. i used the latest magisk and the viper module in the screenshot.
i also didn't make any changes to conf files, just installed through magisk download. rebooted, opened viper fx, gave it storage permissions and turned it on.

Had the same problem, but was able to resolve it by choosing the legacy (non-material) interface when installing the Magisk module. I still flashed the full module and selected the latest version, just not the material interface. It may have been something else, but I've updated my ROM (HavocOS) several times and even done a couple full fastboot stock resets and the issue is yet to resurface.

I've had this problem on an Samsung S7 Edge, S8 Plus, and now, a Oneplus 6.
Everything appears to look good on Driver Status, except "Processing:No" and it's audibly not on.
What's worked for me in this specific situation is replacing the configuration file "audio_effects.conf" in /system/vendor/etc with another configuration file that I found in another XDA thread. So here's the concrete steps:
1. Install the viper4android FX module from Magisk manager that has four devs (v1.7 as i write this) and reboot. I don't know if this method will work with other v4a modules. Note that Processing will work temporarily, but likely won't survive a reboot.
2. Download this file (files_for_v4a.zip) from here:
https://forum.xda-developers.com/ga...laxy-s8-s8-t3596933/post72049061#post72049061
3. Unzip files_for_v4a.zip and make note where it extracted. (You'll need one of its contents, audio_effects.conf, later)
4. Using a file explorer with root capability, go to the following directory:
/system/vendor/etc
5. Copy the existing "audio_effects.conf" to another directory, for example /download, to use as a backup in case this goes badly
6. Copy the file "audio_effects.conf" that you unzipped earlier to /system/vendor/etc, overwriting the existing file.
7. Reboot and test v4a.
Good luck!
Note: The Pulse feature of a custom NavBar in custom ROMS based on LOS 15.1 will not work if you do the above.
Although I'm just a hack, I modded an "audio_effects.conf" file using commits from the above to work with Pulse. I've tested it on my device (despite my lack of know-how, it seems to work for me and others!), so be aware of this if you download the following file and use it (by renaming it audio_effects.conf and placing it in /system/vendor/etc):

Just seeing if I can help! And I did the same sequence of steps on OOS as well ... But I haven't run gravity box in awhile. Hope it works out for you.

I haven't messed with dirac at all, and v4a still works for me.
Some clarification, please:
Did you uninstall the v4a magisk module that came with xXx and reboot?
Then go to magisk manager and install v4a fx materialized1.7 and follow the rest of the steps outlined in my post?

yeah, its 1.7 from magisk repo, disabling dirac seems to help a bit but not everytime

V4A on OP6 with Android 10

This is a bit of rant/question about the new viper4android, but I am struggling to get it working on my OnePlus 6. I'm running Evolution X custom ROM with default kernel and magisk 20.1
For the life of me I cannot get the new v4a working, I've tried a manner of different suggestions from ACP and AML and different steps to install and when I get a working solution it only processes for Spotify and I get no audio at all through from other apps.
The ACP forum does terribly of explaining what each of the three modules do so I've resorted to just testing different configurations of that module to see if I can get anything to work, rather than actually understanding what each module does and thus what modules I actually need on my device.
This is my plee for help, if anyone has got the new v4a processing for all apps could you please post your steps so I can finally move on from v4a legacy.
Many thanks in advance

Download selinux changer magisk (search for it on Google) flash in magisk and choose 'permisive'.

Viper4Android Not Able to Install OB12

The thread title says it all. Does anyone know why V4A won't install properly on OB 12? If you install the drivers and reboot, it just asks you to do it all over again on reboot.

Install busybox with magisk, try use v4a legacy version. Try different v4a versions

Old version needed 2 reboots the current 2.7.1.6 just requires 1 reboot worked fine for me on OB12.

I discovered the culprit for this. It's AML ( audio modification library) it's simply not compatible with v4a on the newest one plus firmware. As soon as I removed a AML, viper installed

On latest Oxygeon OS 10.3.4 having issues installing ViPER4Android legacy from Magisk.
It keeps asking to reinstall the driver....succeed, reboot...and back to the same message to reinstall the driver.
Does anyone have it working? What did you do?

ViPER4Android 2.7.1 install and Tasker automation
Managed to install the latest ViPER4Android 2.7.1 on Oxygen OS 10.3.4.
Installed the APK which creates a Magisk module and you can then update it from there.
You can find the latest version here: https://labs.xda-developers.com/store/app/com.pittvandewitt.viperfx
Driver installs with no issues and seems to work fine though all profiles got converted to the new format it uses in 2.7.1
Tasker automation also broke since the app commands changed to kill/reload it. For anyone interested, these are the new shell commands to use in Tasker to automate bluetooth profile switching in Tasker.
Code:
cp /sdcard/Android/data/com.pittvandewitt.viperfx/files/Preset/Headphone1/bt_a2dp.xml /data/data/com.pittvandewitt.viperfx/shared_prefs/bt_a2dp.xml
killall process.ViPER4Android
am start -n com.pittvandewitt.viperfx/com.pittvandewitt.viperfx.MainActivity
Launch app: Spotify
Run each as root. Repeat for each device you want it to switch settings for. These actions are activated when a bluetooth headset connects.

Did you root with magisk?
If old version
https://xiaomiui.net/how-to-use-magisk-hide-5610/

In Magisk settings, enable Zygisk and Enforce denylist, restart device, go to magisk settings again > configure denylist and check apps you want to hide from root.

forum.xda-developers.com
here is a lengthy thread with another bank, where you can find many many suggestions on how to fix the problem.
i am having x3pro myself using the app mentioned there, but not using LOS18 A11 but Miui A12
with the newer magisk versions
- denylist active
- maybe try shamiko module (denylist enforce off)
- maybe try without shamiko (denylist enforce on)
- maybe magiskhide props config module
- universal safetynet fix
- magisk package renamed
- make sure to enable all options on your denylist application selection to hide all processes
- the application might get root info from google play services (GMS) or play store, where you should also delete cache after making changes and rebooting to see if your change does take effect.

Why don't you try ih8sn since you are on LineageOS.

Was this resolved? I am facing this issue myself at the moment with HDFC App.
ROM - Pixel experience 13 Plus
Device - OP7
Magisk v- 26.1
Universal Safety Net - 2.4.0
Deny List - enabled with many more apps
Example - Gpay, PhonePe, Paytm (All working fine)
YASNAC - Both checks passed
