On 1+ 7, Android 10.

I am facing two problems:

1. Volume stops working. I can raise and lower it with the volume buttons and the volume bar changes, but the actual volume doesn't, it's stuck. This happens from time to time and I can fix it by going to legacy mode and exiting it.

2. Field surround doesn't work properly, neither in normal nor legacy mode. Whenever I enable it, I just get a very strong mid image and little to no surround, even if I max out surround strength and put mid image strength to its minimum. This is apparent when having surround strength maxed out and enabling and disabling the option on the fly, I get more "surround" with it disabled.

I was able to have it work with legacy mode disabled by listening to music with it enabled, and without pausing music I just toggled legacy mode off. Now it works in normal mode but Field surround is somewhat of a deal breaker for me.

What I did is installed the latest Viper4Android zip from Magisk and then uninstalled the app from app drawer. After that just install older version of Viper4Android apk and it works without any problem.

Hi,

Using latest Magisk module v2.7.2.1

It downloaded 443 *.vdc presets to

/storage/emulated/0/ViPER4AndroidFX/DDC-orig

but it doesn't recognize them (see pic)

Renamed DDC-orig to DDC and it didn't help.

If those presets are not deprecated:

Where those files should be?

Why there is no redirection option?

Thanks for pointing that out, I made a magisk update at the same time, so maybe it's not the apps fault. For me it started working again, but not everywhere (in Poweramp for example it's not working), also I hate that you can only change bluetooth settings when you are actually connected to a bluetooth device, I usually turn off viper before I'm heading to my car, but now I have to get in the car and connect to bluetooth first before I can do anything..

Is there a repository with all (magisk) versions somewhere? Or can I somehow solve the poweramp issue?

im using the latest magisk stable and V4A on my pixel 3 running DirtyUnicorns 14.7. V4A has worked with almost all of my wired and wireless devices with the exception of my SoundPEATS True Wireless Earbuds. i cant get them to work. if anyone can shed some help i would appreciate it.

Hi together,

while I am reading the last statements here it turns out that I strongly keep my V4A magisk module 2.7.1.0 as its is working properly on my Motorola X4 with Lineage.. I will not going to update to the 2.7.2.1 version as I am afraid of the problems described above. And I am afraid the impossibility to return to version 2.7.1.0.

Thank you for the hints and complainments

I'm struggling to get Viper to work at the moment.

Running an A11 custom rom (Nitrogen) but just getting the error about being unable to remount /system as rw and having to cancel out of the app. This is on the newest version and I'm running current Magisk Beta as it was the only version of Magisk I could install on the rom.

Any ideas on how to address the mounting error to let me get the driver installed?

TIA
[Android Apps and Games] ProjectAlly:
So after a bunch of troubleshooting, I wiped my phone, installed the latest and last Android 11 for my phone, Magisk canary, v4a through Magisk, converted old profiles and added in convolver impulses, ACP, AML and legacy mode enabled, everything is running now, finally!

But at times it sounds like the audio isn't really processing despite the status being "normal" and "processing" now. Plus there is audio distortion, sounds like a record is playing, with white noise, pops, crackles and skips at times. Music also sounds low, despite having an old preset loaded and the playback gain control being adjusted appropriately.

Any ideas how to clear up the audio? Or is this how things are until future updates?

Maybe I missed something, either way v4a is running so I'm happy, but it's not as awesome as before A11 and 2.7.2.1. Not dumping on the update by the way, just saying.

Thanks to Team_Dewitt for the updates of this mod!

Phone: Pixel 2 XL (Google Edition) Unlocked

Magisk: Latest Canary with updated manager

Magisk Modules: ACP, AML, Viper4Android 2.7.2.1 (all installed through Magisk)

Android: A11 the very last update my phone will receive.

Stock rooted.

Player: Poweramp (pro ed.)

I flashed this one, but it's distorting my external speakers and is buggy, but it does process...so BE CAREFUL. This will get you there until a more stable version is out.

[Android Apps and Games] Areck83:
Doesn't work 2.7.2.1

I recently updated and I saw there's no options to select or see the processing device. I think that was useful to me because I am using the legacy mode and sometimes the phone didn't recognize when the usb dac was connected. I know that the option was removed because the driver it's intended to switch this automatically... but, now this is the entire problem. :rolleyes:

Even with audio compatibility patch Viper doesn't route the audio properly and stuck my playing media, never recognize the usb dac. :eek:

[Android Apps and Games] danny_bhoy67:
Is no one else having the cannot remount /system as rw error which stops the driver from being installed? This is stopping me dead in my tracks.

I can't understand the error as I thought the whole point of this being provided as a Magisk Module was due to the ability for it to be used "systemless", as per the general principle of Magisk?
[Android Apps and Games] autofreak47:
Is there any need to install ACP to overcome compatibility issues?
[Android Apps and Games] Tazmaniiac:
Even in the old version it switched automatically, they just removed the device selection for no reason (maybe visual clarity). In my eyes a bad decision but maybe they will revert that change..

This! This right here!

I can't believe this actually worked!

All my audio issues cleared up, everything is working just like it used to. Yes!

Android 11 isn't so bad on my phone now. Thanks for this solution! ?
[Android Apps and Games] State.of.mind:
Specifically what version did you select? Are you on android 11?
[Android Apps and Games] ProjectAlly:
Yes I'm on Android 11 the last security patch released for P2XL.

So following those instructions I quoted earlier, I already had 2721 installed, so on a whim I thought I'd try what that user did.

I just uninstalled the Viper4Android.apk that came with 2721 only, leaving the 2721 module still installed under Magisk Manager, and immediately installed the 2716.apk that was posted elsewhere in this thread and boom, everything worked! No driver install necessary because 2721's driver is already installed/running.

Just had to navigate system folders to copy/paste my convolvers and presets and everything is good to go now.

So driver status, processing and all that is reporting as it should be "normal".

Alright so first of all: I love the app and it works perfect pretty much all of the time =)

My only problem is that after each restart the app is uninstalled (neither is it in the app drawer nor in the System App-Settings, Titanium Backup doesn't find it as well). The only workaround is to install it again which basically means that I have to install it every time I reboot which is really painful after a while. Is there some way to fix this issue?

If you need any logs please let me know how I can help you out!

There is no Magisk Module on the XDA Labs link. The app states that it supports Magisk, but there is no Module anywhere that I can find.

Click on the "click here" in OP. Sends you to the link, it auto installs.
[Android Apps and Games] cambunch:
I guess the correct answer to my question is that the Magisk Module is automatically installed from the APK file. There is not a separate install for it.

Also, FWIW, I had to install the Audio Modification Library in Magisk for this to work properly on Android Pie.

I've tried the compatibility modules, does not help.
[Android Apps and Games] Joe199799:
Have not updated but apparently you have to run it in legacy mode. no idea what that means just from what I read, I'm still on whatever the update was before and have had zero issues with it. granted I'm still on android 10 so take that for what you will.
[Android Apps and Games] bombadier:
Very helpful post, as others have suggested try legacy mode, reboot the phone then try and play some music, also if you actually read the thread you may of learned you need to use legacy mode, you are not the first nor will you be the last to have problems, no need to try every set of crazy instructions when there are some simple instructions that should work just fine.
[Android Apps and Games] aznpiggy:
it still does not work for me

i have installed:

AML 4.0

ACP 2.3

V4A 2.7.2.1​

the music cuts off periodically when the phone is unlocked, and very frequently when the phone is locked

[Android Apps and Games] bombadier:
Sounds like there is something else at work here, have you made viper/ music app exempt from battery optimisations? I only have the new viper version installed and it works with all my music apps, BBC sounds, fm4, YouTube music Google play(before it got shutdown) didn't need to install acp, what you needing acp and aml for? I would try again with just the latest version of viper installed and take it from there,

Does the music cut out without viper installed? Occasionally when connected to my car Bluetooth the music cuts out for a split second, but starts playing again with no loss in sound quality,

Also when installing the latest version, unlike the old one, just install the app and it does the rest, creates a new magisk module no need to do anything in magisk manager, just install the latest app and that's it.
[Android Apps and Games] Ms0206:
How exactly?

Not sure if I deleted the correct folders, the app still does not uninstall.
[Android Apps and Games] mmarcz:
I appreciate the response. I reinstalled the latest version with magisk. I set it to legacy mode and rebooted, I still get "abnormal" in the driver status.

For what it's worth, I am running the Nov update of android 11. Viper definitely has su status in magisk, but it does not work regardless of the setting. I've tried every combination of legacy and or compatibility mode, and rebooting each time, same abnormal result. I know I can't be the only one with a brand new pixel having this issue.

Looking forward to a new version that works, I've been running viper since the day I bought my Note 4!
[Android Apps and Games] Mr.FREE_Bird:
Saw your post and I thought my findings might come in handy, I had the same issue as you on my OP6 running A10 OmniROM, no matter what I did, I couldn't get it to work. I had to revert back to Magisk v21.0, on that version of Magisk I have no issues. Somehow Magisk v21.1 breaks V4A completely on my side. Hopefully reverting back to an older version of Magisk will work for you too, it's at least worth a try.

Hey guys, I'm using EvoX11 on my K20 pro, and even though viper works flawlessly on a custom kenerl, it breaks the front camera regardless of the kernel.

[Android Apps and Games] KUSOsan:
For some reason Viper will not process on my P3XL running Android 9 unless I change to permissive. Never use to do this. I thought maybe it was from experimenting with other apps like Ainur and JamesDSP and the legacy vipers so I re-flashed a Google stock rom image and set up magisk 20.4 stable again and used kirasakura kernel. Still wouldn't work without permissive. I've tried swapping kernels back to element kernel and still nothing. I've ended up on beta magisk 21 and still nothing without permissive.

The only error I've seen relating to viper is in the magisk logs and they are as follows:

11-22 00:14:57.331 837 838 E Magisk : mkdirs /sbin/.magisk/mirror/persist/magisk/ViPER4AndroidFX failed with 28: No space left on device

11-22 00:14:57.331 837 838 E Magisk : open: /sbin/.magisk/mirror/persist/magisk/ViPER4AndroidFX/sepolicy.rule failed with 2: No such file or directory

11-22 00:14:57.331 837 838 E Magisk : sendfile failed with 9: Bad file descriptor

11-22 00:14:57.331 837 838 I Magisk : ViPER4AndroidFX: loading mount files

I've tried quite a few different suggestions. There seems to be plenty of space in in all of the required partitions. I'm thinking the sepolicy rule file is the one that is causing it but I've tried copying stuff into the sbin/.magisk/mirror/persist/magisk/ and it will not let me. I'm thinking the selinuxrule file. Is the culprit but not sure.

Any help or. Input would be great

Could it be a problem within the EvoX rom itself? I might have to revert to PE rom then. I've asked for help in the EvoX thread but no one helped yet.

It feels more and more like a virus than a useful app to me. I just want to get rid of this completely...please tell me how to remove all Viper-parts.

I do not want to wait for a new update - (it took around 2 years when I am not wrong to release this update) nor do I want more experiments with AML and so on to fix something.

How do I remove this completely from my mobile?

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

Furthermore it looks as if this update broke my fingerprint-functionality somehow...not sure if so and why, but after removing parts of Viper, my fingerprint-functionality is back again.

However, this update brought a bunch of bugs - and I just want to get this stuff away from my mobile.

Everything was fine with 2.7.1.6 - and now this desaster. I am still struggling to remove the app, any advise appreciated how to remove it.

Uninstall the app like you would any normal app.

Uninstall the module from Magisk

Reboot

Check in /data/adb/modules and make sure V4A is no longer there. If it is, delete that folder and reboot.

After I found this https://android.stackexchange.com/questions/200974/how-to-manually-remove-an-app, I was able to remove the app manually at all.

Unfortunately now my mobile does not ask for my pin anymore after startup and does not find my simcard at all?!

Already cleaned Dalvik/cache....I really hope to get this fixed and get rid of this...

---------- Post added at 10:36 PM ---------- Previous post was at 10:23 PM ----------

I was not able to, after I have chosen uninstall, it told me immediately "package-installer closed". Whatever I did, no chance to uninstall.

I installed it by installing the app/apk, after this it installed the Magisk-driver.

Perhaps something broke in the " update-process" as at my first try the Magisk-module was not updated...not sure if my first post is still visible after I complained about the "update-process" and all the problems.

In the end everything was "fine", Magisk-module was 2.7.2.1, app too. Except all the known problems - and my problem that I was not able to uninstall the app anymore.

Be it as it is, now I 'just' have to find out why my mobile does not ask for pin anymore nor find my simcard at all...

Btw, I am using Lineage 17.1 and latest Magisk (21.1).

Like most of the other replies here, can't get V4A working on my 4a running 11 with 21.1 Magisk with and without legacy on.

Have seen some folks mentioning to try Magisk 21.0 and see but without TWRP on 4a that seems to be a daunting task. Is there a known way to roll back Magisk using something other then installing 21.0 zip in a recovery?

Seems the last resort would be to roll back to 10 and play the waiting game.

Thanks in advance for any help or advice!
[Android Apps and Games] beeshyams:
Pixel 4a owner. Instead of trying to roll back Magisk, I uninstalled this version of V4a and installed the previous version 2.7.1.6. Don't change the Magisk module that was installed earlier. No need of any other mods.

Copied previous presets to the folder and all is fine. I am here only to keep track of updates else not planning to update this setup at all
