yes. its working perfectly by this method BUT ONLY WHEN LEGACY MODE is turned on, WHICH I DONT LIKE. this legacy mode's sound output isnt that deep+field surround is not ok like old 2.3.4.0 beautiful driver. i want to use that older driver 2.3.4.0 without messing up android's system Mixers, (like low mic volume when voice-call). please man, can you findout a method where we can use V4A FX Legacy (from magisk download) in latest android 11+miui ? that is all i would LOVE to have ! thanks in advance ..
[Android Apps and Games] netgar:
Why v4a doesn't have permission to see my folders. I can't even save my settings. Why?
[Android Apps and Games] DiamondJohn:
scoped storage in android 11 or mount point changes in A11.

Just because an app is rooted, does not mean it then does everything with root. It has to explicitly attempt (ie request root and then use the root privilege) to do something using root, for root to apply to that specific task.
[Android Apps and Games] netgar:
Thank you for helping me. Wish I knew how to fix it.
[Android Apps and Games] xn0live:
i have android 11, why not woeking?
[Android Apps and Games] RyanCr7:

You're on enforcing mode. Click permissive and permissive will be grey.

Close and force stop viper4android from app info. Then open it again.
[Android Apps and Games] xn0live:
i test a lot of things not working again
[Android Apps and Games] xn0live:
its working, but after reboot its always enforcing mode why that happened?
[Android Apps and Games] RyanCr7:
Turn on Automatically start at boot in SeLinux Mode changer app

After rebooting, wait a minute or two before playing music
[Android Apps and Games] RyanCr7:
As you clearly see in the 2nd picture, permissive isn't selected.

If SeLinux is on Permissive mode, the word permissive here will look grey

The first method works for me on SM-T295 on Android 11 (One UI 3.1). Rooted with Magisk 23.0 and SELinux remains enforcing.

In fact, probably because I have debloated, just installing the V4A apk is enough. No modules are required to be installed or disabled. Maybe an occasional crackle / static but it's rare.

Eu possuo um Moto G7 Plus (XT1965-3) com TWRP (3.5.2_9-0-lake), LineageOS 18.1 e MagiskHide (23.0).

Meu problema é que o V4A só funciona no Spotify e nada mais!
[Android Apps and Games] juergen46:
The only thing to do is to install the Viperfx_2.7.2.1-2721 app from the appendix and the Audio-Modification-Library_v4.0.zip. under Magisk. Then start the Viper app and install the drivers. An automatic restart then takes place. Then activate the Legacy mode under Viper at the top right; this will display the drivers as successfully installed. Now Viper is running perfectly

Good afternoon my friends!

I'm a big fan of Viper4Android. There is nothing compared to him today. However, there are many difficulties and incompatibilities to install on Android 11.

I have a Poco F3 and I am not able to make it work at all.

I've tried everything. I've followed all the possible tutorials, I've formatted the system and still I couldn't make it work.

Installation is normal, but it doesn't run on any Music Player. Even Xiaomi's Native he doesn't perform.

Does anyone here have this same device I have: POCO F3?

Please help me.
[Android Apps and Games] RyanCr7:
If Poco F3 has a different sound system installed e.g. Dolby, you need to remove it first.

1) installed Ainur Narsil's Magisk Module, reboot

2) uninstall Ainur ...

3) install Viper4Android from your zip, install drivers and let reboot

4) installed Audio Modification Library, reboot

5) install Ainur Narsil's Magisk Module and open V4A, install driver again

6) enable Legacy Mode

I tried everything but without success. setenforce 0 did not work on android 11 samsung, getenforce always returns enforcing. adding post-of to magisk didn't work either. after 3 weeks with abnormal viperfx, I resolved as follows: 1) install logcat reader. 2) enable and disable viperfx. 3) open logcat and type 'avc' 4) review calls tagged 'denied' and containing audio.server , audiosever and v4a_fx.so and all audio and viper related calls. 5) each denied call make a rule with magiskpolicy --live 'allow *source *target *type {type of permission}' I needed 2 additional lines: magiskpolicy --live 'allow mtk_hal_audio mtk_hal_audio process {execmem}' magiskpolicy --live 'allow audioserver vendor_file file {read}' use the commands in termux, and go adding a magiskpolicy --live allow for each avc denied viper/audio and test viperfx with each change. after viperfx starts working add all the commands to post-fs-data in the data/adb/modules folder. restart and see if viperfx is still working. sorry for the bad translation.

My post-fs-data here:

#!/system/bin/sh

# Kill audioserver PID if it was initialized already

SERVERPID=$(pidof audioserver)

[ "$SERVERPID" ] && kill $SERVERPID

MODPATH="/data/adb/modules/ViPER4AndroidFX"

magiskpolicy --live 'allow audioserver audioserver_tmpfs file { read write execute }'

[Android Apps and Games] harkoai:
I don't know what happened for it to work for me but I'm really glad it works now.

I probably went through all the v4a android 12 threads on XDA. Tried so many different things even tried installing on a fresh ROM flash several times but it never got past the 'No driver found' popup. Install driver,reboot, and that would always popup when I opened the app

Then today I just decided to open the app randomly and saw that the 'No driver found' didn't popup!

lol

No idea why but I hope it doesn't stop working. Restarted phone to test and it's still working right now.

[Android Apps and Games] DeMiane:
So, I can't install on OnePlus nord 2. Do you have any progress?
[Android Apps and Games] archz2:
I already spent close to 3-4 hours trying various methods to get Viper working on my phone. Always faced failure. I can't get SeLinux to permissive. I tried two apps. Both of them don't work for me. One always crashes, another one changes the mode to permissive temporarily.

I'm using Wavelet. I only require bass boost which it provides me very well. The bass boost quality is as good as Viper in my experience on Boat Rockerz earphones. I have yet to do a comparative test on JBL T450BT.

I guess the sound quality will be same. I still want to get Viper as it's more powerful and has more features which I require less often. I haven't met anyone who has installed Viper successfully on OnePlus 9RT. It will probably take 3-4 months before someone is able to find a successful method as this phone has arrived recently in the market.

Nord has been around for quite a while. You should be able to get Viper on Nord. I haven't searched but I guess there are people who must be using Viper successfully on Nord. Maybe try asking on Nord section of XDA?
[Android Apps and Games] DeMiane:
I've been trying to install for a month) On Xiaomi MI11 on Android 11, with enforced SELinux, installed / there is a way ... the main thing is to figure it out, it's a pity that there are no firmware source files .... Wavelet, well, it's not that, compared to Viper (
[Android Apps and Games] archz2:
You can use James DSP if you're not able to use Viper. It's been praised a lot for its features and has been considered the best alternative to Viper based on what I've read online.

Unfortunately it crashes on startup on my phone.

Did you post your query in the dedicated section of your respective phone model here on XDA?

If you've been trying for a month without success, then I suppose that a solution for installation on your particular device running specific ROM, doesn't exist. It will take some time for the people to figure out a foolproof way for your device.
[Android Apps and Games] DeMiane:
I posted in one of the threads ore my phone, but silence. I'll try again. I came from the Russian-language forum (w3bsit3-dns.com) and I'm not very familiar with XDA. Yes, I've been fighting for a month now, the device suits everyone, except for the sound.

I'll try an alternative to James DSP. Thank you
[Android Apps and Games] Littlemether:
I got a OnePlus 7 phone and have one surefire way to quickly get viper4android active. Install the a-version apk, the open the app and install the driver, it reboots so after that install the b-version apk I post right over the already installed app. Also use small patcher or another way to disable signature verification and signature spoofing to install one apk over another and viper4android doesn't like it when the driver works and will crash. But hey you have a neon driver. Just use small patcher. This way never misses being activated on a beat.

The alternative is to install a rootless driver in twrp and install b-version apk. Still need small though.

I have S10 LineageOS 19 and therefore Android 12. I experience a much better sound with Dolby Atmos and Viper4Android together. I did the following steps:

If you only want to install Viper4Android you can skip Dolby Atmos and Audio Modification Library. Secondly you only need to manage multiple Audio Mods.

First of all install Termux and type in su press Enter then setenforce 0 press Enter to get Viper4Android to work.

Then install Dolby Atmos in Magisk, reboot.

Now install Audio Modification Library and Viper4Android Magisk Module in Magisk.

Set Viper4Android to Legacy Mode.
