I never install or installed any other sound modes.. no a single one.. btw.. yesterday i tried audio modifications library and audio compatibility patch modules ( both latest )

Just because i fed up of installing driver issue..

And today i tried latest version of material design 2.6.0.6( previously used original version ) .. it now shows driver communication issue..!!

I dont find anything weired in installation log. Other than mounting vendor partition error.. but dont know what happend now.. never changed os or kernel in between update.. and vendor partition dont mount properly even through terminal.
[Magisk] Zackptg5:
If vendor isn't mounting in magisk, then v4a won't work and that'd explain the driver issues. You can go to the GitHub page linked in the op and just download the repo from the commit before the 1.7.5 update, then extract it and rezip it but the vendor mount is the problem. You could add "sysover" to the name of the zip. It'll install everything to your actual system and vendor partitions other than boot scripts but it'll circumvent the magisk mount issuea
[Magisk] showlyshah:
Ok.. i will try.. btw.. do u have any solution to fix the vendor mount issue?.. i took twrp log too.. it also shows the vendor mount issue.. but the strange thing is.. the mixerpaths.xml file inside vendor /etc have the viper effect values added to it.. dont know how and when ( may be previously , when viper was working ) it was added.

But now no apps, including viper, terminal, filemanager or twrp can access the vendor folder!
[Magisk] Zackptg5:
Nope, it's a magisk issue. The v4a installer still patches and places the files properly, but magisk isn't mounting them. Are you on stable or beta magisk? Try whichever one you're not on and see what happens
[Magisk] showlyshah:
Oh.. i am on beta.. will check with stable version

---------- Post added at 03:56 PM ---------- Previous post was at 03:53 PM ----------

Also i have a request.. if you can, make an option in the zip file for installing apk as user apk.. because some irs wont work if it is installed as system apk.

---------- Post added at 04:04 PM ---------- Previous post was at 03:56 PM ----------

Oh.. i tried stable version too.. still same.. only thing now have to do is update of os ( i use stock os with flash kernel ) update is out of sync.. on September update.. will update os and kernel and start everything again and will report
[Magisk] Zackptg5:
V4a often gets killed by Android system when installed as user app. If you want an updated v4a, I suggest you try this: https://xdaforums.com/android/apps-games/app-viper4android-fx-2-6-0-0-t3774651
[Magisk] showlyshah:
It was not about updated app.. i already have 2.6.0.5 from that page.. infact i dont like that material design much.. the original one is much more compact design..

I ask to add user app option because, if it is installed as system app, several irs files wont work.. which includes my preferred one.. so i always had to install your magisk module, then disable that apk, and then install another apk as user apk .. that was how i managed to use it till now..

Then too it had a problem , a notification will pop up saying "another app is trying to modiy audio settings... " Or something like that.. but anyway my setup always used to work.. untill last day.. :crying:
[Magisk] lazostat:
I installed v4a fx 2.5.0.5 but i get "no processing" and i can't hear any difference in the sound quality.. I have oneplus 5 with xxx's nolimits magisk rom. In aroma installer i had installed v4a but didnt also work. Then i uninstalled that version and i installed the one in this thread. But still not working.. Why?

I also saw a solution that have to transfer a file but i can't find magisk folder..
[Magisk] Zackptg5:
[MENTION=3783716]showlyshah[/MENTION] and everyone else

Updated V4A to v1.8! Changelog here is that you can now choose if you want the app installed as a system or user app. I recommend system app since android system often kills v4a when it's installed as a user app but the option is now here if you want it. I added the zipname triggers for this to the OP (uapp for user app and sapp for system app)
[Magisk] hachamacha:
Hi & thanks: In post #1, I only see the download link for 1.7.5, not 1.8. Any chance we could get a link to 1.8 (or am I looking in the wrong place?). Many thanks.
[Magisk] Zackptg5:
Sorry, forgot to update the website. All good now :)
[Magisk] raza_maestro:
No matter what i do, viper not working for me. Always the driver error. Don't know what to do now. Used to work perfect on oreo, just updates to pie and facing the issue since then. By the way on stock kernel with latest magisk.
[Magisk] Zackptg5:
Go through the troubleshooting guide on the op. Check that magisk is actually mounting the vendor files too
[Magisk] FraRu:
Hey, why the viper for magisk still v2.5 when the v2.6 is out?
[Magisk] Zackptg5:
This zip only contains official V4As and the material themed version of official. These include: 2.3.4, 2.4, 2.5, material 2.5.

2.6 is an unofficial build meaning that the app itself has been modified/rebuilt. One of the many fixes/improvements to the 2.6 app is that the driver install actually works now (it'll create the needed magisk module too if that's what you're using) so there's no need for it to even be in here. If you're a rootless user, there's a separate flashable zip available on it's xda thread
[Magisk] showlyshah:
Thousand thanks bro...

Everything is fixed now.. for those who have pixel 2 xl, who encounter issues.. here is what i did

IMPORTANT - UNINSTALL MAGISK FULLY USING MAGISK UNINSTALLER ZIP FROM YOUR CURRENT ROM ( only needed if you plan to keep your data , else flashing firmware will wipe it anyway )

1. Downloaded full rom.. ( September update for now )

2. Remove -w from update.bat ( if you want to keep data)

3. Let it boot for one time

4. Reboot into bootloader

5. Fast boot twrp ( use latest twrp )

6. Install your favourite custom kernel ( for pixel 2 xl , if u install twrp on stock kernel, touch on recovery wont work)

7. Install twrp update zip ( corresponding to the twrp image you currently booted into ) - that will install twrp into your device , then reboot .

8. Using latest magisk manager download the latest installer zip ( i used stable version )

9. Reboot into recovery.. and install magisk zip and reboot

10. Now install "magisk_selinux manager zip " - search on xda to find it . While installation, select " permissive " option.

11. Reboot and then install viper4android magisk module 1.8 - choose "install as user app " if you want to install / update viper4android apk OR IF SOME OF YOUR IRS FILES ARE NOT WORKING.

12. Reboot.. thats all you need.. viper4android will be working 101% for you. No need of any other modules or anything else to make it work.

Btw... Thanks a lot ZACKPTG for enabling option to install as user apk. Sorry bro to waste your time asking stupid questions, it was some problem with my ROM.. now vendor folder is mounting properly.. and viper is working perfectly.
[Magisk] Zackptg5:
No problem. V4A should work in enforcing mode though
[Magisk] raza_maestro:
Everything seems to be fine, still everytime v4a asks for driver installation, reboot and again the same thing. I even dowgraded magisk version to see if magisk was causing the issue but turns out there is something else and I can't seem to figure it out and i cannot live without v4a. ?
[Magisk] Zackptg5:
Is vendor mounted? Did you try setting selinux to permissive? Do you have other audio mods installed?
[Magisk] raza_maestro:
Yes vendor is mounted.

There is no other audio mod.

Haven't tested with selinux as permissive yet.

Edit: tested with permissive as well. Still no luck. Can't seem to understand why all of a sudden issue after upgrading to pie.
[Magisk] alfan.y:
Just updated to V1.8 didn't found any issues :good::fingers-crossed:

D6603, Carbon Rom Oreo, Magisk 17.1
[Magisk] 5amar31:
What difference does installing it as a user app make?
[Magisk] Mrpookie:
Performing a search on this thread is a pretty good idea....
[Magisk] dodjob:
Don't know if this has been mentioned, the last magisk module (1.8) breaks Bluetooth audio on LOS 16 (Poco + pie)

The 1.7.4 works flawlessly :)

Hope this helps!

H.
[Magisk] Zackptg5:
1.8 is the same as 1.7.4 other than the capability to install as a user app
[Magisk] my370z:
When i installed v1.8 and select system it's seem to have a problem with install the driver on pixel 2 XL. But when installed as user everything is working great.
[Magisk] dodjob:
I installed 1.8. BT (system)

Reboot

BT audio broken

Deinstalled it

Reboot

Bt audio working

Installed 1.7 BT

Reboot

Bt audio working + of course VFX fully working :)

That's all :)

Grüß,

[Magisk] Zackptg5:
The driver install should be identical between user and system install. The only difference is the location of the apk file. Could you send me your v4a folder in the magisk img when installed a system and when installed as user so I can compare them?
[Magisk] my370z:
I have no idea how to get to the folder. Could you show me how? I would gladly to send you. Thanks for your work.
[Magisk] Zackptg5:
/sbin/.core/img/ViPER4AndroidFX folder
[Magisk] my370z:
Sorry for my lack of knowledge. On my pixel 2 XL /sbin does not see the /.core/img/v4a folder
[Magisk] Zackptg5:
It's a hidden folder so you need a file explorer that'll let you see those
[Magisk] Zackptg5:
Can you post a full logcat after opening v4a?
[Magisk] Ph@nta:
Not sure where the best place to ask this is, but does anyone know if there is a DDC for the Monoprice BHS-839 anywhere?
[Magisk] my370z:
I don't know what happened when I installed as system after reboot then open the app it ask for update the driver, after updated and reboot again. When open the app it ask to update driver and kept on doing that. After I installed and installed as user, everything is working great. Even when recently I installed as system, it doesn't do that again. Don't know what happened. But it working great now as i installed as user. Thank you for your work and your speedy response to help.
[Magisk] aseferfan:
ok i installed Audiomodlib v1.4 and then V4A v1.4, edited scripts according to this

set the script permissions as -rwxr-xr-x using es explorer , rebooted phone and still V4A is showing status as abnormal ://

Please can anyone help out what might be the problem? Using magisk 13.1 and all safetynets have passed

Also my SM-G900F causes heavy lag (even lagging while playing a 240 vid) when i have these 2 modules enabled...anyone else having this?
[Magisk] Nye-uhls:
This post is for v4a+audmodlib by ahrion.

Only install what's in the op. Flash the mod in the op will install v4a and audmodlib at the same time, i believe its a specialized implementation of both.

Also, I'd wait for updates, these modules were not designed for v13.1 and will have a bunch of difficulties until updated.
[Magisk] KenjiHannya:
Try put Selinix in permissive and go to settings - FX compatible click in compatible.

I use Kenzo and Poweramp player and work fine.
[Magisk] xXxNeXuSxXx:
Thanks for your reply :)

Yeah seems like changing selinux to permissive should solve the issue, will try this as a last resort.

I have seen many users using V4A without changing selinux, any idea on that?
[Magisk] KenjiHannya:
Maybe rom

Update

Phone: Samsung Galaxy S4 GT-i9500

ROM: Resurrection Remix v5.8.3 (Android 7.1.2)

Kernel: NevermoreX

Magisk is installed!

I tried installing the V4A module through the Magisk repository, but was unsuccessful. It never showed the app on the app drawer, so I deleted that and came to this thread.

I installed the zip provided by OP, and flashed it via TWRP. It installed the mod, and the Viper4Android apk was now visible in the app drawer. I inserted my earphones, and played a track... the phone rebooted! Realized that my AudioFX was enabled, so let my phone reboot, disabled that garbage, and then played my track. Oh sweet nectar from the Heavens above! I finally got V4A on Nougat! Thank you so much! :good:

Fiddled with a settings a little bit, loaded my previous profile which I prefer, and it seems to be working all right.

At least, if I change the settings, I can make out the audio changes, so I am extremely happy! :)

DRIVER STATUS:

Driver Version: 2.5.0.4
NEON Enabled: Yes
Enabled: Yes
Status: Normal
Audio Format: Supported (shows this even for FLAC et al)
Processing: No (whaat?!!)
Sampling Rate: 48000

EDIT: Scrolled through the thread, and it seems exiting the app might fix the processing problem? What if I reboot?
[Magisk] Didgeridoohan:
I don't think you're using the module in this thread.
[Magisk] xXxNeXuSxXx:
Ohh yeah... I am using the one from magisk downloads section only....

So, I have to uninstall this module and then flash the module which is mentioned in this thread v1.4 and then check if it working.... if not then follow the above script fix....right?

The apk which I have installed from the module download section... that is fine right? or there is different apk based on this module?

I really appreciate you helping me out here :)

Update : Some progress....now only processing is NO. :s I tried to exit by 3 dots.. no go

update 2: Processing worked for sometime like 10-15 seconds and then again went kaput :(
[Magisk] whalesplaho:
Just press on tha 3 dot menu on tha top right corner and exit.... Den launch again, it ll process.
[Magisk] vijaykanth:
Thank you!

Man, I didn't even need to launch the app! I was doing it without the headset on initially. Inserted my headphones, played a track, went to the app, and saw no processing. Exited the app via 3-dots, then the played music just blasted in my ears! It was like a concert in my head! After a month of no V4A, I finally acquired the beast! Aaah, bliss. :angel:

Reopened the V4A app to check!

PS: The track was "Wherever I May Roam" by Metallica. ;)
[Magisk] xXxNeXuSxXx:
Guys I have tried all the steps as mentioned in previous posts.... now the issue is the processing is only ON for the very first song I play after restarting the phone.... then when I change the song it again goes to NO....

I have tried 3 dot exit as well... no go :

It is hit or miss kinda thing...sometimes it works fine

I tried to install the iYTBP Module for Magisk (13.2) by flashing the zip via recovery, and I lost all my modules after reboot! How?

Uninstalled v4a using the uninstaller script, reinstalled v4a, but no result. :(

Checked Magisk log, and it fails after like 3 or 4 steps.

I cleared the Magisk data, uninstalled Magisk, reinstalled it and the log now shows everything running. But cannot see the modules anymore. Is it something to do with permissions? Isn't SELinux on Magisk always on Permissive? I'll try using the module from repo and give an update asap.

Edit: Trying to reinstall an older version of Magisk (12) to check

[Magisk] bohemist:
I had similar issue as yours in the past. What I did was clear exit or closesnthe app, cleared cache and then reboot.

But later I found out a reboot is not necessary as long as you exit the app prior to clearing the cache.

Simply relaunch or reopen the app and it will work

Hope this will work on yours, too.

If you install the material 2.5 from the zip, the substratum themes by deadmanxXD theme it (least linear and valerie do). Linear would probably be closest to amoled black, I use valerie for its transparent theme

Please I need some help, I installed Viper using Magisk, alongside Audio Compatibility Patch and Audio Modification Library.

Viper is working fine in Spotify but there is a big issue, if I click the progress bar (to skip to a different time in the song) all effects from Viper stop then if I click again all effects resume, it's almost as if the bar became a pause/resume option for Viper, anyone else having this issue?

1.8 totally broke ViPER. I'm on a OnePlus 6, Pie. Whenever opening up an app that produces audio and then opening ViPER, it'll freeze the audio app. Going back to 1.7.4

[Magisk] ebeldamasta:
Searched a bit with no avail, been using Viper & 'old' Dolby Digital for a while. It was fine using wired earphones, just started using Bluetooth earphones. Problem started to show, whenever disconnected from the earphones, upon next connection both Viper and Dolby aren't processing. Only reboot or two should fix that.

Any suggestions?

You need audio modification library module to use both. Audio comparability patch can help as well.

Install viper/DD then compatibility patch then modification library I believe

Anyone else have the problem with viper when you change the song it stop processing? An doesn't start processing again till you turn off viper and then open it again and turn it back on I'm on a lg v20 h91820g Oreo on magisk 17.3 I have aml and acp installed.
[Magisk] Mrpookie:
That is strange, have you tried viper installed as a system and non-system app?

Another option to try is to install viper as non-system via Magisk module, then uninstall from app info screen. Then install the app version of viper, this was a workaround I used for proper operation while my ROM was being released. (Due to ROM/magisk? updates I no longer need to do this)

Need 1.7.4 also, could you please share the magisk modul for this version. Cant find it to download

Thanks
[Magisk] GTRanushka:
I also face this issue. Tried your methods. Still not fixed. Tried to kill process with tasker upon disconnect from bluetooth. Still it sticks to bluetooth profile even though it's disconnected. I have to manually disable Bluetooth switch from V4A. V4A Arise app works fine. But sound quality is way low.
[Magisk] Lartsch:
Tip: When you use xhifi with a Bluetooth device, xhifi fails to process the audio when your headset automatically connects after a reboot. Just turn BT off and on and processing will work again.

Sadly, xhifi driver status turns to abnormal state a while after a reboot for me and I have to reboot once again.

Thanks for your hard work.

Best wishes!
[Magisk] Zackptg5:
For your device, 1.7.4 and 1.8.1 are identical. None of the changes in those versions would translate to anything different being installed in your case. Have you changed anything else in that time frame? Can you post a logcat after attempting to open v4a and your magisk log?
[Magisk] SchWeinSAuG:
Thanks for reply.

Well yes i updated xxx nolimitsRom from 3.3 to 3.6.
