Viper4Android drivers vs compatible mode

I am on the latest MM release & kernel to hide unlocked boot loader, rooted with Magisk SU and hidden to use Android pay. I currently run Magisk module for V4A. I have been trying to get V4A to work with installed driver, but after trying several methods suggested in V4A and Magisk forums, it will only work in compatible mode with standard Google play music app. It will not work at all with Pandora or Amazon music player apps. I am not sure what compatible mode means other than it hides the driver information, so I assume it is functioning without driver (?) somehow, with lower quality results? Ultimately would like to get it to work with Pandora, my go to music source, with or without Magisk module interface. I am not sure what the Magisk module is doing if anything as the V4A works the same with the module uninstalled. Thanks if anyone has experience to share.

You have to get V4A magisk, audio modification library and universal deep buff remover (this one you might have to get from the xda thread, the one in the magisk repo seems to be broken) to get viper4android to process in all apps in normal mode.

Thank you for responding, I did try both of these fixes by ahrion, plus he later put out his own magisk v4a module with the fixes incorporated in it, unfortunately no changes, I am wondering if it is something specific to the DT as I have never read of anyone running v4a in normal mode on a turbo.

I've been running that setup I described for a month now and it's survived rom updates as well, never had any trouble with it. Did you get the universal deep buff remover from the xda thread or within magisk manager?

I wasn't sure of source so just loaded deep buff remove from xda thread. Also running the audio mod v 1.4. After reboot neither Google play music or Pandora worked in compatible mode, rebooted to normal mode and no processing from either source. I removed deep buffer mod via his deep buffer restore mod, now Google play music back to running in compatible mode only. Thanks for trying to help me not sure what's different from your setup

For anyone having trouble installing Viper4Android on Pie

So I had trouble installing Viper through Magisk on Pie on my Exynos Note 9. It always told me to reinstall the drivers, but that didn't seem to work.
But I found a solution:
On XDA-Labs is a new version of viper available (Version 2.6):
https://labs.xda-developers.com/store/app/com.pittvandewitt.viperfx
Simply install this version (I chose the beta), give it root permissions and you are set!
I also installed audio modification lib from Magisk to be on the safe side.
Only issue I noticed is that YouTube videos seem to hang for a few seconds before they start playing (I am using YouTube vanced from Magisk). Apart from that everything seems to be working well!
Hope that helps everyone who is having trouble on Pie!

It isn't asking me for root permission?

Strange.
But you are rooted with Magisk and have Magisk Manager installed?
Is the app showing up in Magisk Manager under the SuperUser section?
Maybe trying to install the app again solves your issue.

Correct, and nope it isn't showing up in the superuser section. Re-installing did nothing, it isn't working without root, atleast that's why I think it isn't working.

Yeah it needs root to put itself into some system files.
I just saw they released an update yesterday which is know marked as stable. (version 2.7). Maybe you have better luck with that.

It was working on 2.7 but it suddenly stopped
Now it's not enabled and not processing
Don't know how to fix
(Btw on Samsung Galaxy A8)

This was the only thing that worked. I've been trying different things and searching for hours. The stable version does not work on my exynos note 9. The beta does though!

Viper4Android FX doesn't work

It calling me all time for the driver. I do that every time and I give him magisk root to do that. Any suggestion?

Did i get here some help or not? Then i looking maybe for a other Forum...

Install as system app and allow it to install through the not recommended settings.
U now have to delete it and reinstall it.. Watch the instructions in the thread pls before you become sow passive agressive mate. It is not our fault, ok?

Use this module. Flash in Magisk manager. Choose latest driver, material app, system app, lib workaround, and choose no for the last. (I don't remember what was it)

Hi, I've a Mi9 and tried to install Viper4AndroidFx.. Installation ok, driver installed, but no effect.. tried to set all to highest value to ear some difference but nothing..
Uninstalled it, i tried Viper4Android Legacy, installed as system app and by magisk and chosen all installation option with up volume button..
But still no difference with the stock speaker.. can you help me?
I would like to encrease the volume during a calling. thanks bye

take a look on mi8 or mi a1 forum in xda, there is described exactly which modules in Magisk must be installed to allow a proper function of the ViperFX. Still bootloader locked, so I cannot support by then.

It only works with unlocked BL ofc. Did you tried installing "Audio Modification Library", and "Audio Compatibility Patch" from Magisk repo?

make sure to have installed Magisk Manager, also latest Magisk root installed via TWRP. After this it should be pretty simple, look for the afore mentioned modules in Magisk install them one by one (each single one might require a reboot). After installing them you may install ViperFX, (version 2.3.4 as a system app).

hi, I tried to do everything you said, no one difference..

in a few days when the unlocking time will end will try it myself and in case will make it work, I will post here the process steps.

You have to install the legacy version with lib workaround. For me its working or you can try the rootless version from team_dewitt (look here in xda for it) you only need twrp and init.d injector.

Try this one.

Just to install the apk, nothing else.
Working here like a charm

Hi, I tried the version linked by pokko, it works, but I can't find the way to encrease volume, it works just to have a lower volume, If I set the master volume value higher it doesn't encrease, seems like the stock volume.. is there a way to have an higher volume for the speakers?
thanks

2.7.0/2.7.1 working great on MIUI but with GSI roms it's a different story

if someone can tell me how to get an higher volume please let me know soon.. I'm really thinking to remove root frome my phone.. I've found no one good reason to have it, I don't want to change rom, so I did it just to have 3 things: adaway, encrease volume and use ps3 controller with bluetooth...
adaway doesn't block anything in site that I tried it,
with viper4android my speaker volume is still the same..
miui seems not compatible with ps3 controller.. sixaxis compatibility checker can't works with bluetooth..
the only good thing I've found is the modded youtube version with no ads and background player.. but I've seen exist a versione for no rooted phones too..

c27 update viper4android

Hi,
Now they fixed the fingerprint in the ç27 update. I rooted my x2pro again with Magisk 20.4 So far so good.
Now I really wanted my viper4android Android back, but I get a bootloop when activating the driver.
I tried the aml patch but no luck so far.
Anybody tried this with success?
Luckily it's easy to undo the install in TWRP.
Just run the zip file and it would uninstall v4a.

I managed to get v4a working again after hours trying different methods
Install magisk
Get the aml and v4a rootless zip version here https://zackptg5.com/android.php not from magisk repo
First install AML through magisk install complete don't reboot now got recovery install v4a rootless zip when install complete reboot
After that install v4a apk xda labs version https://labs.xda-developers.com/store/app/com.pittvandewitt.viperfx
Now you have working v4a c 27 update

Wow great.
It works again. I'm what they call a happy camper ?
NB: My setup picture for my Sony WF1000 in ears. I use an old studer.irs for convolver. 2 ms deferential sound. Balance a little to left for compensation and viper clarity natural...
Thanks for helping me out.

Good evening, you can tell me how I update my realme x2pro to c27 and the rooted, I'm on the c11 rooted version and twrp installed, I did not want to update it to Android 10 not to lose the fingerprint, but now that they are fixed the problem on c27 I would like to update it. If there's someone who can help me and give me a link to a tutorial, I haven't found here on xda a tutorial that explains the root and installation of twrp. Thank you

Ah yeah I mean I like to use the movie preset when playing though speakers, so that's great.

Do you guys have any issues with system sounds and ringtone? If I'm not using a convolver it's fine, but with convolver active there are unusual sound glitches and audio pops.

Could you please go into sound settings and then change the media volume slider so it plays that short sound? Nothing weird happens for you?

Yep there is always a bit of lag before the driver kick's in when playing media audio. Also when you start playing music. I don't think there's a solution for that.
I think I just got used ?

Ah yes that's the thing, but the problem is when receiving notifications from different apps.
For instance I get a notification from Viber and there's a slight pop, but then I receive a notification from Facebook and first it plays the remaining sound from Viber then from FB and it sounds really messed up.
It's sad if there's no solution, but I guess I'll keep investigating.
Though I don't think there's no solution, since this always worked fine for me, previously on Nexus 6P, LG V30 and HTC 10.
Btw, my suggestion for the SRS_1_1_Normal_stereo.irs convolver.
Edit the EQ to something like -2dB for the bass freq and -4dB for 4KHz, the rest is up to you.
It gives incredible deep bass and better bass response to the speakers.
Edit: the partial solution for the mentioned issue is to enable attach audio effects option in V4A. I'm not sure if it works for every audio player, but it works with Poweramp. What it does is it disables V4A processing for everything but the music player. The drawback to this is when I'm listening to something in Poweramp and want to play something eg. on YouTube, there is no sound at first. It works okay when I stop/close poweramp. For my usage this is kind of fine I guess, so I thought I would share.

hello everyone and thanks for the explanation everything works correctly now
I don't know if it only happens to me or if it is normal, when I close the multitasking v4a application it stops working, I tried turning it into a system application but the same thing happens, can you help me with that question?

Hey, I have used this method previously to install V4A, but I can't get it working anymore. After trying out custom ROMs, I've gone back to clean RUI 1.0 C38, and following the same steps the V4A doesn't work. Has anyone found a reliable way to install V4A?

Viper4Android on Pixel 4A 5G

Has anyone been able to get Viper4Android working an Android 11? i flashed using the April 2021 Factory Image and have tried following multiple threads and guides, but have never gotten V4A to work consistently/completely.

Viper4android Android 11??
There is viper4android for android11 or I need to wait?
forum.xda-developers.com
This is the Viper4Android I've used for 6+ months. Its the only working, plug and play version I've found for Android 11. You simply download the zip, flash in magisk -- and done. There's nothing else you need to do.
Its 100% safe. Its 100% working. So easy.
I can vouch for it... And love it!

Click on the youtube link, and the zip is in the info there. No need to watch the video. Just flash with magisk or a kernel manager... and done.

I'm on LineageOS for microG 18.1, Proton kernel 1.4, Magisk rooted and this is not working for me. Further more, it mess up with SElinux making it disabled. Fortunatelly, there is an app SElinux switch, that on every boot make it Enforcing again.

I have the 5a but there are no posts yet.....
are any of you getting V4a to work using the USB port ? I run my phone usually into a dac via the usb, but Viper's only working on my phone through the headphone jack.

That YouTube video has been removed. Any chance someone could post the .zip? TIA

Root with magisk and install the Viper plugin, works like a charm on my 4a 5G. Not much else to it.

Not as simple as that for me I'm afraid. Magisk module causes bootloop.
Had the ViperFX_Android11.zip before from that same YT vid (purple/white GUI) and it worked well.
No luck or erratic performance with other versions (black/green GUI), the one from the guy with the name that looks Thai -- Pittanddwwitt idk lol.

Are you rooted normally with magisk per the instructions in this forum? Thats all I've done. Do you have a phone from google or from a carrier?
I got mine from google. Im rooted per the normal instructions. I have magisk v2.7.2.1 and the magiskhide props config modules installed. Ive never had a bootloop with either.
Not really sure what else to try. For what its worth, I cant get viper working on a rooted pixel 3, no bootloops, but the status always says abnormal.

Bought from a 3rd party actually, sealed box, no carrier branding or firmware.
Magisk version (from Canary channel) is f822ca5b (23001) -- that doesn't look right lol... oh, and Systemless hosts module installed only.
I only lost Viper when I updated to the September factory image
<shrug> idk why </shrug->
don't think it happened with other updates.
I'm pretty sure tho that I'd be in top shape, also indebted, if someone could post ViperFX_Android11.zip since the above referenced YouTube vid is gone and, with it, the link and I can't find the same version anywhere else. Thank you very much.

I just received my used 4a 5g. Got V4A v2.7.2.1 downloaded from Magisk v23 working last night...but it was a long trial & error ordeal. First download it showed Unsupported and Abnormal. Thought maybe it needed the Audio Mod Library but that didn't work. Then I tried the Audio Compatibility Patch to no avail. I tried V4A Legacy. Mulitple installs and uninstalls of all the various modules and combinations. At this point I'm not even sure what I did, or in what order/combination, but V4A is installed and working as intended. I do NOT have any of the Audio modules installed, just V4A. Don't know why it didn't work originally, or what made it finally work after fiddling with it for about an hour, but for me, that's my story/advice. Wish I could give an exact process to follow.

Thanks for posting this! The version I had (v2.7.2.1) didn't work as reliably as it should. Often times it wasn't "processing". I uninstalled it and installed yours. So far it seems to be working well.
BIG BONUS - your version allows to view settings for the speaker, ear-buds, & blue-tooth without actually being connected to said devices. I never liked that "feature" of the newer V4A versions.

what about android 13?
