Hi ,

I've got a oneplus 3t , with latest beta.

Viper drivers are not installed.

I've already read the troubleshooting section.

I've just remarked that the viper lib is not present in

/sbin/.core/mirror/system/vendor/lib/soundfx

as it's stated in audioeffects.conf

Here is my magisk log.

For anyone who has a problem on Oneplus3 ( OOS 5.0-5.0.1 ) with an I / O error, try this method

https://forums.oneplus.net/threads/guide-how-to-install-viper4android-on-oneplus-3-3t-oreo.710616/

works great without UDBR

Ps.

Out of curiosity I checked what would happen when I did not change the name of the file audio_effect.conf in vendor/etc, and I received an I / O error. Maybe this is a problem?

Maybe the change of the name of this file before installation also works in the case of v4a installation with magisk repo?
[Magisk] Zackptg5:
?

Audioeffects should say "/system/vendor/lib/soundfx/libv4a_fx_ics.so" in your case

Also, you're looking in the wrong directory. The /sbin/. core/mirror is where the original, unmodified system files are. Magisk modules are located at /sbin/.core/img
[Magisk] tonyfreak215:
Do you have Ainur audio installed? That's what happens to mine when I have both installed.
[Magisk] kojak1989:
Only Viper.

Just got this notification. Never got it on any previous installations. I can't dismiss it but I can hide it so it's not that big of a deal, but if you changed something internally to trigger this I would look into it!

Thanks!
[Magisk] Badger50:
It's only because the V4A material app is not recognized by google play protect. The regular app doesn't do that. It's nothing to worry about. Ignore it, hide it, or disable play protect :good:

Tried to install v2.9 as well as 2.8 on Oneplus 3T (Oreo) : not able to install drivers (I/O error). SELinux is set to permissive. I also renamed /system/vendor/etc/audio_effects.conf to audio_effects.conf_old.....no joy!

Any help/hints are highly appreciated. Thank you

[Magisk] Ragnar Eldur:
Can you please provide the 2.4 version?

It's the last version the fully worked for some devices like mine.

I'm using the Samsung Galaxy S8+

After version 2.4 the module stopped working globally, only processes some apps like the MX Player but all other apps like my music player and YouTube stopped working.

I really need to be able to install the last fully working version.

I can't be without Viper FX, I'm too much of music lover.
[Magisk] dreinulldrei:
Is there a reason enforcing is set to permissive? I see quite some patches for selinux but then everything is set to permissive.
[Magisk] XmechaniX:
I dirty flashed 5.0.1 and latest magisk again. Now I do not get any I/O errors, the driver seems to install fine but after reboot it keeps asking me to install the driver. Such a pain in the ass with this fine app

[Magisk] Didgeridoohan:
If you're running OxygenOS Oreo, it's been found that it doesn't work with SELinux enforcing...

GitHub packages the zip with an extra folder in the root of the zip. Just repackage it and move all the module files and folders out of that folder and into the root of the zip and you're good to go.

SElinux permissive...still doesn´t work

OK, what seemed to worked is, besides magisk module, to flash V4A in TWRP
[Magisk] bond32:
Can I get some assistance - I can't get v4a to show in the launcher at all. I typically use an older v4a install zip which installs to system, but I wanted to migrate to this mod. I can't tell from the log why it won't show, am I missing something?
[Magisk] Badger50:
This is what I did. Either extract the apk from the zip, or using your root browser, go to /magisk/V4A/vendor/app/V4A/V4A apk. Then install it like any other apk ?
[Magisk] toastyp:
The newest audio modification library breaks v4a processing on the v20. It force the system/etc/audio_effects.conf file to vendor/etc/audio_effects.conf which makes v4a unable to process effects on the v20. Attempting to delete this file out of vendor with a root manager fails, as it says the resource is busy. Tried with multiple root managers and twrp file manager. In the 2.8 version this wasn't an issue as we could delete the file beforehand, and the modification didn't re-add the file back. Maybe there's another way to delete the file out of vendor/ but I am unsure of what to do.
[Magisk] tinOFbeer:
Try rename file in /vendor/etc, not system/vendor/etc

Since I can't find anyone else having the same sort of issue I encounter i'm posting it right here.

(OnePlus 5 OOS 5.0.1/Oreo )

I would say that everything works fine 70% of the time.

It's like everytime I plug a headphones Jack the sound is coming unbalanced. It's not my headphones problem or even a hardware issue because it also works fine when I unplugged/plugged it quickly back multiple time before having the sound correctly balanced.

It's clearly a software issue no doubt about it. (It can also randomly appear when browsing through YouTube videos, when everything was working fine before unplugging the headphones)

I know my problem is a little weird because I can't find what's causing it. I tried disable Dirac app and service but no change.

It's not like V4A don't work on my device but it's kinda annoying. Any help from you guys ?
[Magisk] Pablo.x:
What if you turn OFF (and then ON) Viper when you've that unbalanced sound instead of unplug and plug?

It would also be insteresting to check "Driver status" on Viper's app when this happens.
[Magisk] nosphor:
Will try this as soon as possible and let you know the results. Thanks for the help.
[Magisk] nosphor:
Ok, tried it and still no change.

Driver Status were all ok.

Think I'm gonna reflash the rom and then reinstall magisk and this module. Let's see how it goes.

EDIT : Still present

Don't know what to do next.
[Magisk] nosphor:
Quick update

: I searched a little deeper through the OnePlus forum under the bug reports section and what a surprise. I'm not the only one having this problem. Guess OnePlus will have to sort this out asap.

Sorry for the trouble. :)
[Magisk] NiTrOwow:
It installs good, I changed to this because with my Bluetooth headset I really need a equalizer and this rom doesn't have one.

I have tested the old version and it seems to be OK. The original audio lib that came with my phone had better sound quality on speaker. it's really strange, trying the new version now.

So the new version seems to work better (on my device), thanks! Really happy with it :)

Edit2: Just tested my bluetooth headset, I guess it's the audio tracks that are of poor quality (low bitrate). But one strange thing is none of the settings in V4A under Bluetooth headset doesn't seem to have any effect on my MadCatz F.R.E.Q. M. The only settings that have a change are "Master Power", and "FireEqualizer". The headset does not support this, or am I deaf? :(

Edit3: hmm.. After installing V4A lastest version magisk started to act strange v15.1 .. So I updated magisk to the latest stable build because after installing V4A SafteyNet did not pass anymore, also my system partition was locked and card emulator wasn't working any longer..

Issues is caused by Audio Modification Library. When this one is enabled applications can't do "mount -o rw,remout".
[Magisk] Pablo.x:
Did you uninstalled Dirac apps before installing and using V4A?
[Magisk] anujyadava:
Hello all

I am using v4a with ainur sauron and both working fine with magisk 15.3.

But when I recently my phone once ( for any reason) v4a stops processing and phone needs one more reebot/ reflash in magisk to get it working.

Anyone having the same problem or has solution to it??
[Magisk] fake2die:
Sorry,,my bad then..

As this is in magisk subforun I asume people use magisk..

Try different viper mod then as enforcing kernel need more mod than the original,,like from mokee v4a..

I'm using magisk and its work fine with enforcing kernel..

How to Install Viper4Android

Hey,

I just flashed magisk on my RN3 SD Kenzo, LOS 14.1 latest build, however i don't have any idea about how to use the modules and make Viper4Android work on my device (Or dolby or Any other sound improving software for that matter). Sorry if it's a bit of a dumb question but can someone please guide me on how to install it from scratch. Thanks a lot :)
[Magisk] IagoJevaux:
Just download the zips in this thread and Dolby thread and flash them via recovery. They will identify Magisk and install accordingly. Nothing fancy needs to be done.

Just wanted to say thanks. I'm not an audiophile but only wanted to fix the quiet Bluetooth volume in my car. My 6P is quite wonky with BT volume.

Maybe this would be helpful to some, here's what I did:

1. Read this entire thread

2. Clean flashed PN (7.1.2), BeansGapps, Magisk 12

3. Flashed the V4A in OP, set up phone

4. Disable MusicFX, reboot to recovery

5. Flashed deep buffer remover, clear cache/dalvik

6. Reboot

Works flawlessly. Thanks ahiron!!

I can boot with AudModLib module, but when I add this one, version 1.3 and 1.4, it won't boot. Nexus 6, Pure Nexus rom 4/23 build. I originally had the Viper4Android module in the repo installed (since removed it) and no other audio mods. Tried removing the other Viper module before flashing this one and removed the Viper4Android app too. Am I missing something?
[Magisk] alexbelgium:
Thanks for bringing V4A to Magisk! Just a small request : would you have time to create a 2.3.4.0 version?

I (and some other people, based on my browsing of xda) prefer this version for its sound depth. Thanks !

I found a problem.. After installing V4A module in Magisk a NFC application called NFC Emulator doesn't work any longer. It is not able to mount system I get the error Device or resource busy.

After uninstalling V4A the first time the problem did not go away, so I've reinstalled Magisk from scratch. Installed V4A again and guess what, the problem was back.

As soon as I uninstalled V4A the problem disappeared again.
[Magisk] MeetFace:
I think there's a Magisk module for the Axon, perhaps I should try that method. My worry is that the Pixel is a bit different of a beast. Maybe I'll run a TWRP full backup before trying. Thanks!

Hi!

I have a problem with this module! I tried to flash it, and to install the old V4A! Everything went fine but when I rebooted my phone and tried to open the app, it didn't work, I tried to delete the module and reflash it but still got the same issue, everything worked fine with the new version but I really want to install the old one. Anyone got the same issue and managed to solve it?

Thanks in advance for your replies! :)

Here is a twrp log, I hope it will be useful. :/
[Magisk] sd_matto:
Moto Z2 Force (US Cellular variant) running Oreo.

Viper4Android was not working when installed. Manually edited the post-fs-data.sh file to include the SE Linux policy fixes for the Pixel (2x) and for the Pixel 2 (1x). A little bit of experimenting showed that all that was necessary to get Viper4Android working was the 1x Pixel 2 SE Linux policy fix in the post-fs-data.sh file.

Please incorporate this info (i.e., Pixel 2 fix now required for Moto Z2 Force (at least one running Oreo)) into future patch updates.

Thanks for a great Magisk module!
[Magisk] Lownita:
Hello, I'm running this module on an op3 on latest Omni ROM weekly, 8.1 Oreo, magisk 15.2. Would it be possible to make it work with selinux on enforcing, since I can't without having to set it to permissive first.
[Magisk] Sytis:
Since you are not on OOS, the installer shouldn't set SELinux to permissive in the first place but apply the patches to make it work in enforcing. Otherwise something else set the status to permissive or something went wrong (at least that's what I assume).
[Magisk] derKoder:
I downloaded viper for magisk , after install it , it says need to download driver , i click yes , and it says i/o error and doesnt want too download the driver and want me too restart it , after i restart my phone still got the same problem , any solution? Im using lineageOS 15.1 (oreo 8.1)
[Magisk] saccentekennedy:
You know what... I just installed the 2.9 version of this module in my OnePlus 5T yesterday, and I had 14 hours of wakelocks for this! Massive battery drain. Any ideas?

Also I'm pretty sure the module isn't recognising I'm on OOS and isn't setting SELinux to premissive, so I've been setting it in the advanced settings in the app. Is this right?
[Magisk] saccentekennedy:
On second thought... I've tried uninstalling and disabling V4A and all associated Magisk modules and it doesn't seem to be related... Maybe a false alarm.

[Magisk] Lownita:
You have to set selinux to permissive that's how it worked for me.
[Magisk] perobot:

[Magisk] Lownita:
Why does it not work on Omni ROM though?
[Magisk] Zackptg5:
Thanks. I've had that sepolicy patch in v4a for a long while actually but only for pixel 2s with v2.9. I'll make it for all devices again in the next release. So in the mean time, just remove the #pixel2 from in front of the line in the post-fs-data script
[Magisk] Lownita:
Would this also make it work on Oreo custom ROMs?
[Magisk] Zackptg5:
It should work on any room. There's a troubleshooting section on the OP that should address any issues your having
[Magisk] Lownita:
It's only working on permissive mode for me, otherwise driver status is abnormal. I guess I have to try and edit the post-fs-data script accordingly to make it work in enforcing then.

One thing just in case you need to know...

The viper4fx from the latest ARISE Magnum Opus 20180105 Stock Edition which has your Magisk module works on op3T Oreo 5.0.1 stable if I set the kernel to permissive mode but the aml viper module 2.9 still gives I/O error even in permissive mode...Ring any bell???

So after installing 2.9 I'm getting I/o driver needs to be installed when I try it fails gonna need some help here logs attached

[Magisk] Ragnar Eldur:
I am using the Samsung Galaxy S8+ running TouchWiz aka Samsung Experience 8.1 based on Android 7 and the last version of this Viper FX magisk module that works correctly is 2.2

Can you please try to find out what went wrong with the newer versions that is causing the module to only partially work for systems like on my phone?

Only few apps like the MX Player works with the newer versions but everything else including the music player don't.

Just to add 2 infos :

- on the last version of my Oreo 8.1 rom on a OnePlus X, I had to flash the module via TWRP. Via Magisk, it didn't activate the drivers.

- today, the playstore app scan tells me that V4FX app is a "malaware" and asks me to unistall.

Could you just add in the troubleshooting post 1 that Play protect see it as an dangerous app but that is a false positive?

Guys, I have this weird problem I'm not sure I saw here - initially, after reboot V4A works fine - driver status is fine and all effects are enabled - and processing says "Yes" (I can clearly tell the difference when listening on my 5X, I tell you that). Then, after some time (note no reboot in meantime) when I play music it says Processing: No.

I was looking through troubleshooting section, but nothing really resolves this - I have to reboot to make it work back again.

Now, if I set app compatibility mode to 'Compatible' everything works fine, though my understanding is that Compatible mode is kind of worse that Normal mode - is that true? What's the practical difference? Anyone having/had similar issue?

My device is Google Pixel 2 (non-XL) running patched stock ROM 8.1 with January security updates and V4A 2.9 (new/non-materialized). What device, ROM and versions are you using?

Yes, I do have not quite the same issue here with V4A in normal mode. After a restart , it works for a while when I start playing music right away. Then if I stop music for a bit (unknown length) and start it up again, V4A no longer processes, and I have to restart the phone again. My issue with compatible mode here is a bit different than yours in that when I have that mode set, nothing works at all with V4A on my device. It does not process at all, and when I tap driver status, I don't get anything at all for the usual popup message showing the status. It's like that menu choice doesn't work.
