Hi, for OnePlus 8T OS 11

all i had to do is:

Using latest build of magisk 21.3

i have installed module: Audio Modification Library

Reboot!

Then install Viper4android module in Magisk

Reboot.

Open the App build v2.7.2.1

Give ROOT access, and install driver!

Device will reboot!

Open the app, go to settings, and enable Legacy Mode!

Press the driver icon and you will see that it's working!

Enable master switch set your settings and enjoy music!

No need for ANY other things!!!

Do not uninstall things in ROM, do not put any files in android/data/

No need to switch Selinux to permissive!

Thanks to Devs, i can enjoy music with my new monster phone! :)
[Android Apps and Games] underskyzx:
Turning SE Linux permissive worked.

Now Legacy Mode works.

---

Another one here that updated Magisk and lost V4A.

If I check Legacy Mode it mutes for 2 seconds then sound come back with no changes.

Someone with better knowledge should look into this issue so we don't keep guessing and messing with our phones!

Hello everyone!

I have viper working on my Android 11 Pixel 2XL (custom rom). However, I notice that my newest Sony bluetooth speaker shows "abnormal" on it. This has a new option in the bluetooth settings: "HDaudio:LDAC". Is there any work on an update to Viper for newer devices and features?
[Android Apps and Games] Dj Telo:
It comes from here maybe...

Pixel 3

Android 10 (Pixeldust)

v4a 2.7.2.1

Is there any fix for v4a not processing on youtube in normal mode (not legacy mode)? v4a works fine with music players except youtube. I have installed ACP and AML.

I have no problem in legacy mode, all is fine (youtube, music player, video player), but battery draining fast.
[Android Apps and Games] crackerjack1957:
Version 2.7.1.6 works with youtube & others on my 4a Android 10 stock rom.

Stay with older version until they get the bugs out
[Android Apps and Games] RyanCr7:
Great app!

But I miss that extra loud feature in latest v4a.

Is there any chance you guys can bring it back?
[Android Apps and Games] Dj Telo:
I just wanted to report that since I installed this module on a Pixel 3 XL running stock Android 11 I have experienced the following issues recurrently:

- Android Auto not launching when plugged in my car.

- WhatsApp freezing after video call ends.

- Bad microphone sound reported by my callers via WhatsApp video calls.

- Random freezes and unresponsive power button.

After uninstalling the module everything is back to normal.

I am the only one experiencing these?
[Android Apps and Games] Lord Sithek:
Isnt increasing output gain enough? You can use some loud convolver too
[Android Apps and Games] RyanCr7:
How do increase output gain? I actually never checked that.

Nevermind. Figured it out 😊
[Android Apps and Games] Lord Sithek:
Good :) You can use playback gain control as well.

EU Android 11- Magisk 21.4

1.flash magisk module v.2.7.2.1

2.open the app build v2.7.2.1 give root access, and install driver! device will reboot!

3.delete the app build v2.7.2.1

4.install the app build v2.7.1.6 (apk)

5.open the app... give root access

6.done...
[Android Apps and Games] RyanCr7:
I do feel it's a bit louder cause OPT is at 0.0db now(which was -1.9)

Still it's nowhere near what my stock rom offered. I did make a clean install of V4A.

Q1) Anything else I can do?

Q2) Some convolvers like Dolby pro logic and Zloud seems to make the sound louder but they aren't good and makes the sound buggy. Can you suggest some convolvers that will bump up the sound without making it buggy?
[Android Apps and Games] Lord Sithek:
You can increase output gain under "Master limiter" section too.

I used to use Dolby Pro Logic convolver and it gave me no disturbance at all... Now I don't use any convolver, so I don't know
[Android Apps and Games] RyanCr7:
Master limiter is what I was looking for. Thank you you a good man

You obviously have achieved what you set out to do, however, if it wasnt enough, another route may of been to try enabling your FIR equalizer, and raising every band up a bit.

Noob needs a little help!

I wanted to try Viper4Android (running a Redmi Note 8T with Custom ROM MSM Xtended XQ 13, Android 10 and being rooted with Magisk). I tried to download the apk from the link of the OP but I am not able to reach the download link. Where / How can I get the apk. Or is it enough to flash the Magisk module? See attached screenshots.

Please let me know what I should do.

First installation don't work for me too (Samsung Galaxy S10 Android 10). Fault to Magisk 21.4 ?

Solutions #5,065 and #5,077 don't work for me.
[Android Apps and Games] oscillum:
Does not work for me either, same phone and os. Maybe it really is Magisk 21.4, could it work with 21.3?

I have noticed that after running it some time and letting music play, it gets louder according to my settings, but only for 1-2 seconds, and drivers still display disabled etc.
[Android Apps and Games] _mysiak_:

Magisk 21.4 with viper working fine for me

But i have to switch legacy mode on
[Android Apps and Games] oscillum:
What was your procedure? I tried Legacy to no avail. I'm using

- Riru (Core) v21.3

- EdXposed (Sandhook) v0.4.6.1
[Android Apps and Games] RyanCr7:
Sound is quite loud on my music player but really low on youtube.

Searched on Google and seems like a lot of people having the same issue.

Viper works system-wide and this shouldn't be happening right?
[Android Apps and Games] quantumcog:
I am not using riru core or edxposed

Im in selinux permissive tho
[Android Apps and Games] Lughnasadh:
Viper hasn't worked system-wide in quite a while (i.e. notification, ringtone sounds, etc.). I'm wondering if it is processing at all when you are using YouTube? With some streaming apps (e.g. YouTube) you have to enable or disable legacy mode or install ACP for V4A to process. Since it seems to be working on your music player but not on YouTube, maybe this is the problem?
[Android Apps and Games] DiamondJohn:
Have you tried switching to enforcing? Originally my Viper install was setting my phone permissive. I changed the boot script to switch to enforcing a minute or two after boot, and it is all working, and is now enforcing.
[Android Apps and Games] RyanCr7:
Legacy is enabled and yes it's processing while I am on YT. Just the volume is low
[Android Apps and Games] regularmen:
does anyone else has this loud bang sound when changing songs with Dynamic System active? what caused it? I hope it's not damaging my headphones.

I've got this issue with the latest version.

Before I updated to the latest it worked fine.

I'm rooted, but deleting/uninstalling the app with TitaniumBackup doesn't seem to uninstall the driver. Because each time I reinstall, it doesn't prompt me to install the driver.

After uninstall I did wipe the cache in TWRP.
[Android Apps and Games] ecompton59:
titanium dont work after android 9 only to freeze apps or connect to market ? what kinda install magisk or twrp ? the updated viper here is best and safest v2.7 https://zackptg5.com/android.php#viper is link screenshot to be safe
[Android Apps and Games] Dioser:
And why should zacks be safer? You know its the same right. Unless I'm unaware. Zacks only benefit the old irs profiles still. ? But enlightened me. Both are build by dewitt zack just added the possibility to use old profiles, if this is the case. I'll correct you, wavelets is the safest option. As it works non root. 👍 Still created by the boss Dewitt v4a no root. Zack = flash, Dewitt = just indstall..

V4a was my only reason to root. But with wavelet, this is just a water (waste) of time. Been rocking it for a year, rock solid.. and the 2700+ headphones profiles are only increasing. ❤🙏👌💪

I'll advice any to try at least. And I'll promt any who got issues with v4a.. v4a sure it's more competent, indeed, but most will find wavelet plenty.

Was not near meant to be a commercial. Lol. Just a recommendation. ❤💯 And maybe a heads up for those don't know..

All credits goes to the pittCrew and no hate on zack ❤👌🎶 dude knows his game
[Android Apps and Games] Uluru25:
I also appreciate Wavelet but what I did not figure out is a way to define more than 1 custom preset. I am missing this because I want to modify the sound for bluetooth speakers (and since I use more than one I would appreciate to define more than only 1 preset). Anybody knows how to do so? :unsure:
[Android Apps and Games] ecompton59:
Without Zack no mod would work He's made and help do a lot and viper4arise quit dev 2017 viper 2.4 and think his team has found sweet spot just set irs files right kind too much power will blow fuse on amp or radio I've done it with busted speakers
[Android Apps and Games] Dsteppa:
I actually just installed the APK from the latest version (beginning of Jan this year).

Never knew Titanium didn't work anymore on 10 (But seems like I'm still on Android 9) Galaxy S8
[Android Apps and Games] Dsteppa:
Please do share Wavelet AS WELL... NEVER HEARD OF IT. The only reason why I also got root back in the days was because of V4A.

I did do an install through TWRP btw, but as far as I can member the driver status still stayed on abnormal.
[Android Apps and Games] shadowstep:
You can find it in the Play Store:

Wavelet: headphone specific EQ - Apps on Google Play

Headphone specific equalization with lots of customizability

[Android Apps and Games] oscillum:
I'm still having problems with V4A not working on my Galaxy S10+ with Magisk/Riru.

I tried the solution provided in #3,647 but to no avail.

Following the guide where you first install Viper, then AML, then install Viper drivers and reboot, then disable AML in Magisk, Viper doesn't prompt me to install again, but also shows disabled etc.

Anyone with a similar problem who got it to work? I'd be really thankful for any advice!

As stated in my last post, I'm running Riru (Core) v21.3 (since EdXposed and modules like GravityBox don't work on v23+ yet)

EDIT:

Since the solution in #3,647 was provided by ultradj83, maybe you could help me out here, even though it's been quite some time since your post...
[Android Apps and Games] Dsteppa:
For now I do hear a clear difference between V4A and Wavelet, but only been playing with it since yesterday.

Does anyone know if the paid options for Wavelet make a big difference?
[Android Apps and Games] Camack:
I have 2.7.2.1 installed on Android 10 (OneUI 2.5) and it is working fine with legacy mode on but sometimes the processing status is no when using Youtube Vanced or Poweramp and I have to toggle off and on the legacy mode in Viper to have it processing again, is this normal?
[Android Apps and Games] Lughnasadh:
On Android 10 the most common usage it to have legacy mode turned off except for streaming apps such as YouTube. For Poweramp, make sure you have DVC disabled.

Also, some people may need ACP to have streaming apps process properly.
[Android Apps and Games] _mysiak_:
I am on Android 10 and legacy mode works fine in every app (youtube, youtube music, netflix,..). Sometimes it happens that on the first launch of an app, Viper doesn't process the audio. I have a Viper widget on my homescreen and it is enough to just click on a profile to "wake up" Viper. It works flawlessly afterwards.

P.S. wavelet is completely different app and while it has a nice idea behind it, profiles for headphones are usually completely rubbish and not worth using

Edit: my apologies, Wavelet is much more mature now and from screenshots looks very nice. It didn't have features like custom profiles/equalizer when it was launched. AutoEQ headphone profiles are unfortunately still mostly rubish, but that's not app's fault.
[Android Apps and Games] oscillum:
Please don't give people an attitude. You don't know about their equipment and ears, and it does not really matter anyway. I know what I want with V4A, hence my posting and asking in the All Root Solutions for Viper.

I actually tried Wavelet and for me it just doesn't cut it. Not that I'd need to justify, but there's no playback gain control, convolver or dynamic system options. Like _mysiak_ said, it's a nice idea but not really an alternative.
[Android Apps and Games] Ms0206:
Still no fix? Very good...

What I not understand:

So why is everyone here still struggling around with 2.7.2.1, legacy mode or strange 'fixes'??

Isnt it clear that 2.7.2.1 is completely defect? Garbage? Should be deleted and forgotten? Producing much more problems than it solves/previous versions?

Why has still no mod here removed the 2.7.2.1 file - the root of all unsatisfied users and the last ~10 pages of complaints and defect mobiles/OS' - instead of complaining about complainers and the evil, unthankful users?

Stop 2.7.2.1, provide 2.7.1.6 again - and everyone is happy. Not?

2.7.2.1 went terribly wrong, was a big mistake - no problem, everyone makes a mistake - but why are the devs and mods here watching this for months and doing nothing, waitin until more and more people run into the now known problems?

In my opinion the mods here should delete, stop or warn for 2.7.2.1 usage - or devs give people a working update.
[Android Apps and Games] Ms0206:
So, again, for everyone having problems, errors, asking himself whether to use legacy or not or unsatisfied with ui:

Here is the original 2.7.1.6 (from Telegram group). Works fine out of the box (at least here) and solves all problems of the last 15 forum pages. (not tested with A11). Have fun
[Android Apps and Games] bolo808:
TYSM! This worked perfectly (y)

P4XL/Android 11/Magisk 21.4 Stable/Viper 2.7.2.1
[Android Apps and Games] Ms0206:
What I said ;)

You could have saved hours of writing by just using 2.7.1.6 from the beginning.

Never use 2.7.2.1. Be happy.
[Android Apps and Games] oscillum:
No, in all seriousness, installing v2.7.1.6 on its own did not work for me. It only worked for me after downgrading Magisk and I wrote the guide in case someone else has the same issue, since at least VictoSab (#5,087) had a similar issue with the Galaxy S10+ on Android 10, I think.
[Android Apps and Games] Ms0206:
You had to downgrade Magisk? Ok...

I installed Magisk 21.2 on Lineage OS 17.1 and Viper 2.7.1.6, everything was fine.
[Android Apps and Games] oscillum:
I suppose downgrading Magisk was the solution for me, I didn't do anything else differently.

I installed Magisk on Samsung's stock ROM, maybe it has something to do with this. Eitherway, I'm happy it works and if my explanation helps anyone, the better.
[Android Apps and Games] swiftez:
Did you disable DVC in Poweramp for Viper to work?
[Android Apps and Games] oscillum:
Yes, I double checked. With the latest Magisk Canary version, it didn't work no matter what I did. Now that I'm on v20.4 everything works just fine.
[Android Apps and Games] swiftez:
Did you just uninstall 2.7.2.1 and installed 2.7.1.6? If so, did you force stop the app and cleared the app cache/data before downgrading?
[Android Apps and Games] oscillum:
I simply uninstalled v2.7.2.1 and then installed v2.7.1.6. No force stopping, no clearing cache/data.

Rebooted for good measure and testing.
[Android Apps and Games] Dsteppa:
For some reason when re-installing V4A Magisc Manager doesn't want to give it SU permissions, anyone know how to do it manually? There is never a window that pops up in order to grant permission when opening it for the first time

Followed this to a T and i still get the Status: Abnormal and Enabled: No on pixel 5

Not sure how to go about doing this.

Do i have to open command prompt?
[Android Apps and Games] _mysiak_:
Install file manager which can access internal file system with root access (I use Total Commander for Android) and follow the instructions. Or you can do it from PC via ADB (either from a command line, or use Total Commander for PC with ADB plugin).

No I haven't yet, I've already gone back to magisk 20.4 but I might try this method if I get time. Thanks
[Android Apps and Games] oscillum:
I'm curious, did downgrading to Magisk v20.4 work for you?
[Android Apps and Games] ProjectAlly:
I've skimmed some of the latest posts, I guess I'm confused as to why everyone has to downgrade Magisk to get the 2716 build of v4a to work.

I made a post a bunch of pages back, with the exact version of 2716 I'm using to this day. I started on a Pixel 2 XL and am now on a rooted stock Pixel 5 and the very latest version of canary Magisk 21.408, and every month I flash the latest Magisk after updating OS with monthly updates (Pixel 5), then when that's done I just flash the A11 build of v4a 2716 I've used all along and it works perfect, no downgrading, it just works!

Just to make sure, I even used the latest Magisk canary (21.408) and flashed this on my old rooted Galaxy Note 4, and it worked immediately.

Forgive me for being confused, not trying to stir up anything, it just makes no sense to me that a method or version of v4a that's working for me and some others I've seen in this thread, everyone seems to be overlooking.

I'm willing to upload my presets, and the v4a I'm using again if it helps anyone! :)

Wouldn't hurt I'd say hehe.

[Android Apps and Games] kanyazsombor:
I've tried this on OnePlus 6T on Pixen 11 and works fine even without legacy mode. Also switching viper's main switch (master limiter) on and off during playing switches processing on and off nicely without needing to stop playback.

After tried it on OnePlus 6T OOS 10.37 (android 10), and works also nicely. No need for legacy mode, and processing seems not to switch off occasionally.

Edit: seems to work without legacy mode with Spotify but not with YouTube Music

Then I turn off viper4a module, keep apk, keep aml module on, then continue to live.

After many times reboot (and install others magisk modules, edxposed modules), I turn on viper4a module with a hope: someday it will be good.

Then it work perfectly. I dont know why.

1. Put your preset into the correct folder [/storage/emulated/0/Android/data/com.pittvandewitt.viperfx/files]
