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.

Viper4sound - Nothing happens

Today i unlocked and root my OP6 5.1.9
Went to Magisk and did install a Viper4 sound.
The problem is that......nothing happens. Try diferent modules, always uninstall before....and even so, nothing.
Even try APK + drivers.....nothing. Whatever i do, nothing change on default sound. i use Poweramp.
Is this something to do with Permissive something? On my previous Mi NOte 3 i had do uninistall FX and mod INI.
What should i do??

You need to ROOT with Magisk, flash Busybox NDK via Magisk and the 1st of 3 Viper4Androids in the DL section of Magisk...

Long time user of Viper4Android. Across several HTCs, since Android 4.4 IIRC. Lately moved to the OP6.
Really....all you need is OOS 5.1.9, Magisk 16.0 (and the process that gets you those two things). Then install the ViPER4Android FX v1.7 module in Magisk. Choose the Material Design option when you activate/install V4a. If you get the I/O error installing the driver (first time running of V4a), then you need to enable SU in Magisk for V4a (as it didn't ask when you ran V4a).
If Poweramp is your only playback method. You'll need to make a change in the EQ/sound control setup (of PowerAmp, not V4a) for V4a to work. I ditched Poweramp long ago, so don't remember the specific change to make it compatible with V4a.
Lastly, are you direct connected to the OP6 (via the 3.5mm audio) or connected via BT? Those throw issues into it as well.
Don't get discouraged...it will work. I have V4a on my OP6 working via the 3.5mm connector, a BT connection to a vehicle system, and to another BT 3.5mm stereo receiver/adapter to headphones. It however does not work, to one of my BT devices, which uses LDAC BT connection to the OP6 (an EarStudio ES100).
HTH. More questions? Ask away.

Guys!
I apreciate the effort but nothing.....installed Busy BOx NDK, ok, and the first one (1.7):
However, when check drives status, i get a Enabled: NO - Processing: NO
Magisk 16.4
Root OK for Viper.
Maybe some previous driver install full of trash...even log seems to say it did clean old stuff....

Using Spotify connected via BT to vehicle.
It's either a remnant of another audio mod, or the EQ setup in Poweramp is not right. It's very specific. Google 'Poweramp Viper4Android fix'. And ignore the response of putting v4a in compatible mode. Not necessary. It's a special way if the EQ settings in Poweramp. One of the reasons I switched to USB Audio Player Pro.
HTH.

I notice you have xXx installed.....and i have OO 5.1.9 stock....
I really want earphones,....all the rest for me is not important...

Yes. xXx installed now. I ran about 2 weeks only with OOS 5.1.9, Magisk 16.4, AdAway, and V4a.
xXx installed BusyBox and V4a. But BusyBox is not needed for that.

Strange why it doesnt work for me....

Check this thread: Using-Poweramp-Viper4android
The Poweramp specific settings are mentioned. I don't use Poweramp anymore, so can't test. But remember doing this.
Or, there is another audio mod being persistent. This conversation just came up in the xXx thread. A user still had some DolbyAtmos mod enabled. Got it deleted, and V4a immediately started working.

mAN!
You are my hero!! When i start mess with sound proprietes i did start see results..
When i did use default app, everything was on, finally!
Gonna try now to put Poweramp working.
P.S. Strangly didnt found a big diference betwheen stock audio an Viper4sound . This is new for me....need time to tune it.
Love you guys! Tks XDA!

And Poweramp works!!
Quote:
"If you are having problems with PowerAmp, you first need to do this: Go to PowerAmp Settings - Audio - Advanced Tweaks. Now disable Direct Volume Control and enable Music FX!"
Maybe it helps someone else....
Thank you ALL!!

try installing audio compatibility patch module from magisk. then see if anything changes.

Dont have it installed...

Glad you have it working. If you are playing with V4a....then you likely enjoy great sound or at least tuning it to your liking. Setup your audio stream (no matter the source, Poweramp, Spotify, Pandora, Tidal, etc.) to the highest quality. If you're using Poweramp, then it'd be your sound files (FLAC or similar at the minimum). Then, get some quality mid range headphones/canalphones. Earbuds not. If you want to research (and be completely overwhelmed), visit head-fi.org.....and 'sorry about your wallet' as they say over there.

Uninstall the driver and flash the Magisk module one, so the processing sound will work flawless.

I did it on my Mi Note 3, but here im still afraid to do something wrong, especially with this alien A/B partition stuff...
For the record i still owm a Piston 2 earphones, ZS ZSR and ZS SR10 earphones... so i have good stuff!

Not familiar with the Mi Note 3. Does it use Magisk or SU?
In general, I've found that if you are using a Magisk setup device, it's just install the v1.7 module I mentioned above, and all is usually good to go (as long as there aren't other audio mods enabled!). If you are using a device that uses SU, you may also have to do some boot up kernel config to set SELinux to unenforcing, rather than it's usual default of enforcing. You don't need all the other fluff....xposed, busybox, etc. etc. to make V4a work properly.

My wallet's unfortunate casualty :silly: of my reading Head-Fi.org too much. But, these give some truly awesome sound....
Serious Listening.....Flare Audio Pro
Most of the time.....iBasso IT01
Radsone EarStudio....usually connected to IT01s

Mi Note 3 i had to erase SoundFX or whatever, inject Viper4sound 2.3.5 file and other stuff i don`t remenber...
At moment i only use Magisk and Viper4sound, so no chance of other stuuf conflict!
Thank you Guys!!

Android 10 + Viper - conflicting audio mod found?

So the thread is simple. I wanted to install Viper, to lower my media volume cause even 1 is too high. Now... I was able to install Viper easily on a Pixel 3a XL.
Just grabbed the Magisk module and off it went.
Not here though.
I get a message saying...

Tried everything since. The app from XDA Labs, the MOD lib it talks about. Nothing.
Maybe something left some junk somewhere? But how do I clean out all the Viper remaining parts?
Thanks for the help...

Same message. I can't get Viper to work. I have it installed via Magisk but the audio fx don't work. It's the stock ROM and rooted.

Doesn't work. Tried. I also tried the AINUR mods. In the end they just bricked the current setup on my phone.
Something is messed up in OxygenO and OnePlus won't care anyway, so it's what it is. I mean, the delayed notifications have been plaguing OOS since what? 3 years? So hey, maybe in 10 years they'll take a look at this. Until then.... just move to LineageOS or some other rom as an alternative.

If you have installed another sound mod, you need to install aml after installing viper. Otherwise, they conflict. That's all there is to it.
As for delayed notifications, the only thing that I can think of is that your messaging apps are not set to don't optimize in battery settings. If not, they will be set to sleep and you will only receive your notifications when you open the app.

Common sense guys , It has Dolby installed , so that's why it detects it . Just install Audio modification Library and Audio Compatibility Patch , solved.

Try viper4android v2.7.1. Just install driver 2x ( will reboot 2x too) works great for me.

This is an issue with Android 10. This is how to fix it:

I managed to install viper on op7 OOS10.0.1 with bluspark kernel with the following method:
1) uninstall every AML and ACP and viper stuff and reboot.
2) install ViPER4ANDROID 2.7.1.0 apk from xda labs and open the app but dont install driver. put the app in background
3) go to magisk>downloads and install AML module. it will ask to reboot. dont do it.
4) go back to viper and install driver. it will automatically reboot.
5) after reboot go to magisk manager and UNCHECK (NOT DELETE) AML and open viper and install driver again.
6) now your phone will boot with viper installed
Note: (if viper driver is installed but has no effect then go to viper and click on 3 dot menu then click on 'attach audio effects' once viper start working you can detach it). you can use App Systemizer on magisk repo to systemize viper app to priv-system app so that it doesnt get killed in background. you can also hide its always on notification. viper will always run in background. but i saw no battery drain difference. Enjoy

Worked for me in Stock Rom oos 10.0.1?

Or you can easily flash in magisk repo

Good alternative module repo magisk James DSP (DCC and irs files supported)

How are you guys rooted on oos 10?
I lost root when I updated and when I went to redo it I found that the process changed for Android 10.

What is you parameters on Viper ? For Compare.
Thanks

I installed it the complicated way, thats written up there and it worked fine. I had to wait because i lost root in the oos 10 update, because i flashed magisk in the wrong way. And there was no twrp that worked for me, fastboot boot didnt worked at all, so i flashed magisk to the boot image and i got root again with viper4android and everything works fine.

Question Anyone get ViperFX functional on their OP9?

received Buds Z for my OP9 purchase and have very slowly converting to the new phone (rooting, stability and assure privacy issues were addressed) and was very happy with their performance with my rooted OP6 on A11-Pixen OS with ViperFX. Without VIper, the sound is lackluster. even a downloadable EQ makes minimal difference.
Attempting to convert fully to OP9 today and installed viperFX mod form magisk but when I attempt to perform the initial launch to download and install the driver, the phone just reboots without actually getting the driver installed. Im not sure if its a hardware compatibility issue or the fact the OP9 root isnt as full and fleshed out like the one on my OP6. (something about DM verify and/or selinux enforcement? idk, I am pretty lame at the deep understanding of android 11s workings)
I know there are a few other magisk mod for audio listed and more that i could possibly find that arent and add myself via zip installation but even if one ends up working, I will still be aiming for VIperFX as my preferred solution.
If anyone has a solution, plz reply (or whatever possible replacement you've chosen)
PS. I swore the buds z touch controls were suppose to be customizable. anyone else unable to set custom controls for them?

In magisk, install "audio modification library". That should fix the driver issue.
To customize the touch controls, go in Settings, bluetooth and device connections, bluetooth, settings cog next to the buds, headphones. Now you can customize them. Not a lot of options though.
You might need to install the oneplus buds app first.

Same issue. Tried ACP as well, just gave up on it and using the inferior built-in Atmos

No, but I did install James DSP and it's working just fine.

@applyscience
After alot of trail and error I finally got ViperFX working on my OP9 !
You must install magisk-permissive-script_v1.2 and audio modification library modules in Magisk and of course the ViperFX

Glad you got it working! I wonder why I didn't need to do that
Hopefully it works for everyone else.

Just use JamesDSP. Same functionality as Viper, and works 100% of the time.

Can you tell me how you got it working in more detail? Because this isn't working for me

Okay it randomly worked for me after installing the BusyBox magisk module, then the Audio compatibility module, then the Audio modification module and then viper. After that the driver installed but did not work. After setting the selinux mode to permissive and switching to legacy mode in viper it worked flawlessly.

Im trying for several hours now, i have tried everthing i found including this Thread
(https://forum.xda-developers.com/t/app-fix-100-working-viper4android-for-android-11-devices.4213647/)
Nothing worked for me anyone any idea, i have allready updatet to the latest OxygenOs (11.2.4.4.LE25BA) Maybe thats why it doesnt work?
