Hey! Thanks for the quick reply! I did try to do this but when I open the 2.7.1.6 version it mentions some partition problem and will never fully open the app no matter what I seem to do. Maybe the apk I got off APKMirror is bad?

I guess I should try the link that was a few pages back maybe?

Edit: Just tried this again and it is FCing after I do the apk install and try to open it.

Edit 2: Found a workaround in installing the 2.7.1.6 apk after uninstalling 2.7.2.1 again. Opening it and getting the FC. Then uninstall 2.7.1.6 and reinstall 2.7.2.1 and will have good driver status untill reboot then would have to do that process again...

Here's a link to the APK I found in the Telegram group and that works for me

Going back to Magisk 21.0 doesn't make a difference, Viper still fails to detect what audio output I'm using, yesterday I was listening to music for like half an hour on my earphones and simultaniously there was the same music blasting out of the speakers, without me noticing it. Had the same bug on Magisk 21.1, so the problem is with Viper for sure....

Why is there no list with all the previous app versions, every ****ty app has a github with versions dating back many years, yet viper breaks everything but only offers to let me go back like 0.0002 versions??
[Android Apps and Games] Mr.FREE_Bird:
How come you're unable to remove it completely? What doesn't help is that you provide only little to no information, how can you expect anyone to help you out?

You could've at least explained what you already tried to remove it.

Removing the module via Magisk should work fine, that will get rid of V4A. And after doing so you should be able to remove the V4A app as well.

"After its impossible to me to remove this stuff since days, I can only advise others against installing Viper4Android in this state."

So basically you're going to ignore everyone who is able to use V4A without issues and assume that your unfortunate experience means that everyone will run into issues... Nice logic man.
[Android Apps and Games] Kiastinger:
In the viper4android folder in Android storage.
[Android Apps and Games] Mr.FREE_Bird:
Have you already tried to completely uninstall Magisk and dirty flashing the ROM you are currently using? That might get things to a working state again and should help with getting completely rid of V4A.
[Android Apps and Games] Ms0206:
Yrs, not uninstalling Magisk but dirtyflash the latest update of LOS + Gapps + Magisk 21.0, without success - I was still not able to uninstall the app.

Tried this again minutes ago as it seemed to be a possible solution to fix my missing phone-functionality - now my mobile completely refuse to boot, I am sitting infront of a black screen.

Very frustrating...as my mobile is encrypted I have to find out now how to save my data and have to reflash everything from scratch I think.

I assume something broke as I manually uninstalled the app, but I dont know.

This teached me to never install any updates again before I am not 101% sure it does not break my system somehow :(
[Android Apps and Games] Ms0206:
Recovery-mode does also not start anymore. I'll go to my computer now to check what I can rescue...

This update should be removed immediately for public in my opinion...I am out, good luck [MENTION=9073985]Team_DeWitt[/MENTION].

Hope you learned to always perform a backup before performing modifications to your device.
[Android Apps and Games] cambunch:
Add me to the list of not being able to get V4A working on a new Pixel 5. On the latest Magisk (21.1) and tried a variety of solutions posted here (AML and/or ACP modules, Legacy mode on/off, loading the 2.7.1.6 apk). It is just always stuck in the "abnormal" state for me.
[Android Apps and Games] aznpiggy:
install v4a 2.7.2.1 via magisk > install aml 4.0 via magisk > open v4a 2.7.2.1 app and grant su to install drivers > auto restart > uninstall v4a 2.7.2.1 app > install v4a 2.7.1.6 apk > open 2.7.1.6 app and grant su (it force closes itself or stays blank right afterwards) > uninstall v4a 2.7.1.6 app > install v4a 2.7.2.1 apk > turn on legacy mode

it stops working once you restart your device though...
[Android Apps and Games] cambunch:
Installing 2.7.2.1 apk OVER the 2.7.1.6 installed APK was the step I hadn't seen before, and that does work. However, not surviving reboot is really crappy. I wonder what logs we can pull to figure out what's happening here...
[Android Apps and Games] aznpiggy:
if your device restarts > uninstall v4a 2.7.2.1 app > restart > install v4a 2.7.1.6 apk > uninstall v4a 2.7.1.6 app > install v4a 2.7.2.1 apk > turn on legacy mode

its a pretty quick fix since you dont need to touch any magisk modules, but all the presets are gone
[Android Apps and Games] danny_bhoy67:
It seems like most people are having to enable legacy mode to get the driver to run properly. What is the difference between legacy and normal mode?

It almost seems to me that kegacy should be the default and there should be a setting called "future" for the people who are able to run the driver as intended!
[Android Apps and Games] xdidnothingwrongx:
So many people complaining that it wont work with there 4-5 year old smartphone. How about supporting the devs so they can work on the software in there FREETIME. So strange that people with legacy devices complain that the latest version wont work.... If you want the latest software then first replae your old junk.
[Android Apps and Games] danny_bhoy67:
My device is three months old and running the latest iteration of Android. Hardly "legacy".
[Android Apps and Games] Tazmaniiac:
If they did not mess up the latest updates or at least provided a way to revert back to an older version people would not complain and wait patiently for a fix
[Android Apps and Games] PATAboy:
Magisk 21.1 is the problem.

Once on a working magisk no need to update it

([emoji88]Cr Droid[emoji88])
[Android Apps and Games] PATAboy:
I'm sorry, I don't get what you mean. What I suggest is downgrading Magisk not updating.
[Android Apps and Games] Dubbaya:
If on 11 one would need 21.0 like myself. Magisk 20.4 won't work on 11. You know how to go back to 21.0 without using recovery as my 4a doesn't have the option?

Would be open to rolling back Magisk for the time being until this would get updated. But don't know how to do so in just the manager route.
[Android Apps and Games] PATAboy:
I can get you the 21.0 url, but I suggest checking the Magisk's GitHub for older releases.

You can flash Magisk from within Magisk, just Install Magisk as you would install a module from a file, you can downgrade this way too.

THIS METHOD WORKS
[Android Apps and Games] danny_bhoy67:
Downgrading from 21.1 to 21.0 fixed the issues for me, albeit I have to run it in legacy mode.
[Android Apps and Games] PATAboy:
That's great to know! I'll edit my comment so that it doesn't suggest incorrect stuff.

FOR ANYONE ON MAGISK V21.1 AND GETTING ABNORMAL STATUS:

It appears the problem lays in Magisk v21.1.

- If not on Android 11, I'd suggest rolling back to the latest Stable (which ATM is v20.4, v21.1 is beta channel).

To do so go to Magisk > Settings > Update Chanel > Stable.

Then return to Magisk's main page and press "Install" in the Magisk box. "Direct Install" and "Let's go". Magisk v20.4 should install, reboot after that.

Then, I'd delete the Viper4Android module and app, and reinstall it.

You may need to enable legacy mode for V4A to work.

-If on Android 11, downgrading to v21.0 also works.

Get Magisk v21.0 from Magisk's GitHub releases page. (https://github.com/topjohnwu/Magisk/releases)

Then flash the Magisk v21.0 .zip from within Magisk, just Install it as if it where a module.

Then delete Viper4Android's module and app, and reinstall the module.

You may need to enable legacy mode for V4A to work.

If you have a working V4A that persists after rebooting, you could try and update Magisk to v21.1. It looks like once V4A is installed correctly it stays that way, but I just tried this one time and YMMV.

IF YOU CAN ONLY GET V4A TO WORK ON LEGACY MODE:

Under Legacy Mode, play some music. Without pausing the music, disable legacy mode.

Music should keep playing while Legacy Mode is disabled. Try pausing and resuming, V4A may get to work with Legacy Mode disabled this way.
[Android Apps and Games] Dubbaya:
Thanks for a lot of good info here!

Question about installing 21.0 via the module way... Would you be able to use the "select local boot image" option as this is needed to get rooted with the 4a? Would I install 21.0 via your method and then go back into manager and reinstall again with the select boot image option?
[Android Apps and Games] PATAboy:
IDK much about this method, but I'll try and help you.. Are you already rooted or are you rooting it for the first time?

Edit: Patching the boot image should be needed for the first install only, then you should be able to install magisk as a zip whenever you want
[Android Apps and Games] Dubbaya:
The former would be the case. Already rooted with 21.1 currently.

So with that I will go and do your method you mentioned from the releases section on Git, thanks again!

Edit: Can confirm like the other mentions that downgrading to 21.0 is a solid workaround when using the latest V4A on 11. Great find and the method mentioned above to rollback worked great!

[Android Apps and Games] Dubbaya:
Yeah was going to ask what device, but you got it covered as yeah 21.1 added support for the 5 and 4a 5G.
[Android Apps and Games] PATAboy:
I see, I've just tried updating to v21.1 with V4A already installed and it works. I guess the problem lies in the installation process under v21.1.

I'll try uninstalling V4A, and reinstalling it in v21.1. If its abnormal, I'll see if I can fix it and relay the info to you

GOT IT WORKING!!

1. Uninstall the V4A module in Magisk and app.

2. Download and install The SELinux Switch from XDA

--(https://xdaforums.com/devdb/project/?id=22073#downloads)

Note: Google Play Protect may display a warning, just tap "Details" and "Install anyway (unsafe)"

3. Open the app, grant it root acces, and tap "PERMISSIVE".

Dont set it to "ENFORCING" before you are told.

4. Install V4A from Magisk, dont reboot. Enter the new V4A app and install the driver.

The phone will reboot.

5. After it reboots, open V4A.

6 Enable the Master limiter, then head to settings and enable Legacy mode

7. Reboot and Status should read Normal.

8. Open The SELinux Switch, and set it "ENFORCING". You can now delete this app.

Please tell me if this works for you.
[Android Apps and Games] aznpiggy:
are you using pixel 5 as well? i managed to get it to work but it goes back to abnormal after restarting
[Android Apps and Games] PATAboy:
Nope, I'm using a OnePlus 7 with Android 10, but I'm under the impression the problem lays with the way Magisk manages the sepolicy rules during the install in v21.1, so this is more of a Magisk version specific problem, not a device related one.

It would be great if you told me if the method I just added in the other reply helps you, it seems to persist after reboot in my device.
[Android Apps and Games] aznpiggy:
the status says normal after uninstalling selinux and restarting the device

but soon after playing music via spotify, the phone freezes a bit and goes back to abnormal

thanks for trying though

ill just avoid restarting my phone and wait for the new patch

-Pixel 4xl on Android 11 / November

-uninstalled all audio mods then reboot

-downgrade magisk to 21.0 using zip from github / reboot

-(don't reboot till finishing this step) install AML, then viper. Switch to viper app, grant permission and install driver then auto reboot.

-install audio compatibility patch. (Not everyone needs this) then reboot and everything should be working.

If you use headphones, plug headphones in and the settings will show up. The same with bluetooth and the rest.
[Android Apps and Games] Dubbaya:
Yeah like the above mentioned as well, the lastest updates removed that option and will dynamically add/remove options based on the current output audio stream.

Certainly has been a contentious feature update based on the replies in this thread but nonetheless that is why. :)

White Noise

Hey fellas, I've tried a lot of audio mods. And viper is good but v4a always creates a hissing / kinda white noise to the audio.

I really "pixel peek" when it's music. Try this and tell me the result please

1. Lower volume to 1

2. Choose a soft start track

3. Reduce the vol to 0 while playing and back to 1 volume . See if there is a lot of noise. (Without any viper settings except master ON)

JamesDSP or stock don't have that noise even if I crank up the high Hz.

Everyone try and gimme a feedback please. I've been using many phones so it's not the device.

Hello Everyone :)

I'm new to the forum and Android modding in general, so please excuse any noob statement or question.

Anyway the app works great and improved very much the audio quality through (almost) all of my devices. Kudos!

My only question is the following: is there (or there will be) any chance to make V4A work (or processing, as you want to say) even when my Sony WH-H900N headphones play music using Sony proprietary audio codec LDAC? Because as long as it is enabled in the bluetooth connection properties of my device (OP3T running Nitrogen 10 with magisk), V4A doesn't process the music but as soon as i disable it, V4A starts working as usual.

Any Reply or suggestion would be very appreciated :)

POV:

You just want to listen to music, but Viper 2.7.2.1's core functionality is a no-op. Devs haven't pushed commits since late October, and the forum is wild with activity about how broken it is. Reports of legacy mode, compatibility mode, audio modification patches, and the like all don't work.

Helpless, you turn to buying more android devices in the hopes they will work. An old oneplus 3 seems to work but it cost me a fair amount.
