[Q] Unable to install driver for Viper4Android XHIFI

Friends
I just downloaded the Viper4ANDROID XHIFI Mod on my rooted Galaxy Nexus running Android 4.3 and also has BusyBox 1.21.1 installed
After installing V4A when I opened the app I was prompted with the driver I want to install; not knowing which is the right one for me I selected CortexAX with NEON (please advise me on the best to choose)
After that I repeatedly got the message "Driver install failed. Please confirm your phone has been rooted and busybox installed" - both of which has been done already. No matter which driver I select, I keep getting the same error.
I previously installed the V4A available on the Play Store but thought of getting the one straight from XDA
Please advise on how to get the driver installed and which is the right one for me
Many thanks!

There's a reply the official thread mentioning mounting with Terminal Emulator. I don't have enough post count to ask that member if there is anything necessary after installing drivers, like unmounting, or anything else.

Did you ever solve this issue? I'm seeing the same problem.

Hello
Viper4Android XHIFI project has been stopped now by the developer .First try different drivers during installation .If it doesn't work try reinstalling busybox , it happened to me sometime back . Before that try V4A FX app also if it works then XHIFI may be incompatible . Last chance is to get the desired V4A driver (libv4a_xx_xx.so kernel file) from extracting apk and to place it in /system/lib/audio/ folder manually and reboot .
Hope it works

Thanks. V4A FX app appeared to install the driver fine, and I guess I don't need XHiFi if I have that. However, even though it is installed, it doesn't sound as if it is having any effect. I'll try uninstalling and re-installing it again.

Cheers ! Did you reboot after installing V4A FX driver ? If not do it and by itself V4A will be disabled and you should enable it in the master power controls in different sections (phone-speaker,headset,bluetooth,usb) of V4A app . Then you can modify each settings for your needs in realtime while hearing music . You can also check if driver is working or not in options/Driver Status . If any of these doesn't work use FX compatible mode in options .
Hit Thanks if it works !!

Things are working now, thanks. I wound up needing to remove XHiFI and V4A FX, then re-installed just V4A, re-installed the driver, rebooted, reset it to be default music effect, and it's working again.

I had this issue with my LG G2 (Verizon model) I was trying to install the Viper driver (High Quality sound) but my busybox couldn't install. "Unable to verify my root" error. So I tried a different route...
Use this app to install busybox (instead of the official one) and it should work.

Where can I find that kernel file? I am having the same issue. The message is "Driver Install Failed, the busybox found on your device does not work.
This usually means you installed the wrong or broken busybox, V4A needs stericson bisybox to work. if you sure about having installed the proper busybox, then please confirm your device has been totally rooted."
Phone- Sony Xperia C
1. My device is properly rooted.
2. Busybox is same to which the app redirects.
What are my options?

Try reinstalling busybox from this app and try again. Manual installation of V4A driver is not working now.

Been trying to install the driver for Viper4android, but it says the busybox installed is not the right one. I'm rooted and have no custom rom installed. Anything to do so the viper4android can instal on my lg g3 t mobile?

This fixed it for me:
"If anyone is having trouble installing driver for Viper4Android Just go to superSu settings and uncheck the namespace checkbox and reboot. After that the driver for Viper will install."

No succes after uncheck the namespace checkbox and reboot.

If this helps, running:
Busybox Free version 1.24.1
Installed in system/xbin AND system/bin (dropdown on Busybox install screen under version)
SuperSU - Mount namespace separation UNCHECKED
SELinuxModeChanger set to PERMISSIVE

That did it! Thanks for superfast support!

Cant get Viper to work properly

Hey guys,
since i got my Oneplus 6, i couldnt get viper to work quite right. Most of the time its just shows "Processing: No" till i restart it and after like a hour or device switch it turns off.
I tried:
Copying the Audioeffects.conf from system/etc to vendor/etc
Using Magisk Audio Compability Module
Using Alternate Magisk V4A Module
Using a Magisk Rom with Build-In V4a (currently xXx 2.8)
Disabling Dirac and Services
but nothing worked
thanks for your help

i had the same but then i tried to use the other viper release from magisk and it worked. there is this one called hifi and fx

Try exiting the viper app with the 3 dots top right hand corner. That is what worked for me

Sounds to me like you need to disable the battery optimizations for Viper. It's almost as if your phone is detecting High battery drain and shuts down the app

I'm using the Android p beta and i don't have the problems with viper as i did with oxygen os 5. it's always processing for my headphones, either plugged in or Bluetooth. the only exception is sometimes after receiving a call while listening to music, after the call is over and my music resumes, viper is no longer processing. not every time though. i used the latest magisk and the viper module in the screenshot.
i also didn't make any changes to conf files, just installed through magisk download. rebooted, opened viper fx, gave it storage permissions and turned it on.

Had the same problem, but was able to resolve it by choosing the legacy (non-material) interface when installing the Magisk module. I still flashed the full module and selected the latest version, just not the material interface. It may have been something else, but I've updated my ROM (HavocOS) several times and even done a couple full fastboot stock resets and the issue is yet to resurface.

I've had this problem on an Samsung S7 Edge, S8 Plus, and now, a Oneplus 6.
Everything appears to look good on Driver Status, except "Processing:No" and it's audibly not on.
What's worked for me in this specific situation is replacing the configuration file "audio_effects.conf" in /system/vendor/etc with another configuration file that I found in another XDA thread. So here's the concrete steps:
1. Install the viper4android FX module from Magisk manager that has four devs (v1.7 as i write this) and reboot. I don't know if this method will work with other v4a modules. Note that Processing will work temporarily, but likely won't survive a reboot.
2. Download this file (files_for_v4a.zip) from here:
https://forum.xda-developers.com/ga...laxy-s8-s8-t3596933/post72049061#post72049061
3. Unzip files_for_v4a.zip and make note where it extracted. (You'll need one of its contents, audio_effects.conf, later)
4. Using a file explorer with root capability, go to the following directory:
/system/vendor/etc
5. Copy the existing "audio_effects.conf" to another directory, for example /download, to use as a backup in case this goes badly
6. Copy the file "audio_effects.conf" that you unzipped earlier to /system/vendor/etc, overwriting the existing file.
7. Reboot and test v4a.
Good luck!
Note: The Pulse feature of a custom NavBar in custom ROMS based on LOS 15.1 will not work if you do the above.
Although I'm just a hack, I modded an "audio_effects.conf" file using commits from the above to work with Pulse. I've tested it on my device (despite my lack of know-how, it seems to work for me and others!), so be aware of this if you download the following file and use it (by renaming it audio_effects.conf and placing it in /system/vendor/etc):

I haven't messed with dirac at all, and v4a still works for me.
Some clarification, please:
Did you uninstall the v4a magisk module that came with xXx and reboot?
Then go to magisk manager and install v4a fx materialized1.7 and follow the rest of the steps outlined in my post?

Clean audio

Hi guys,
I have some problems with audio after installing viper (beta). I've already had viper for a week and all worked perfectly (also upgraded to 2.7 stable). Since today that I decided to uninstall momentaneously the driver and now, if I reinstall viper, I have a broken audio (idk how to explain) for some reason.
Do you guys have any idea?
I think it would be good to clean all audio files, or something like this, and reinstall viper.
Thx in advance.
EDIT: Forgot to mention that I'm on AEX.

I would try a dirty flash of your current rom

First delete your current viper from magisk and android apps. Now go to magisk manager downloads. Search for viper and install the 3.4.2 version with lib workaround (last option you have to choose). Reboot and search for notification helper remove by zackptg5. Install and reboot and you should be fine.

I'll try but I've always installed viper by using the app and not the magisk module because it wouldn't install the driver. I have to say that I've never tried to install it with lib workaround... I'll let you know how it goes.

It's the "Remove volume listener library"
For "Remove notification_helper effect" you'll need the "Audio Modification Library" magisk mod, which messes everything up on our phone

It's working, thank you.

I got them work with ADL but it has a bug that sounds won't play on Bluetooth earbuds.

Viper4Android "install drivers" loop after update

While I know there are other threads regarding similar programs with this rather temperamental app, I didn't find any thread that fit my case exactly, nor one that really fixed my problem, so.. sorry if this is a duplicate.
Anyway, situation is this:
Viper4Android 2.5.0.5 (installed through magisk 20.0, MM 7.3.5) was working perfectly (or atleast somewhat) before recent update. Now that my phone is on Oxygen OS 10.0.1.GM21BA, the driver for Viper fails to install (it says "driver installed, please reboot etc.", but upon reboot it says "please reinstall driver, etc.", and the loop continues).
What I've tried so far:
>Reinstalling Viper - no difference
>Disabling SELinux (both through the Viper itself and through some outside app that might or might not work) - no difference
>Read that deleting audio.fx in vendor/etc/ could fix this problem - couldn't find the file
>Yelling at the phone - no difference
>Also read somewhere that an issue might be that Viper might be denied storage access permission, but the app don't seem to be requesting any permissions at all.
Anyone have any tips or pointers at what else I could check or try? Music just sounds kinda bleh without Viper.

You need to install drivers twice.

Mhm, sure.
Though, to be honest, this was among the things I tried before. No difference.

Uninstall your current Viper and reboot. Sideload Viper 2.7.1.0 apk or use the Magisk module. Install the driver and reboot. Once back in Android, install the driver again. Should work. If not, go into V4A settings and put in compatibility mode.

Hmm, installing drivers multiple times made no difference in 2.5.0.5, and yet in 2.7.1.0 that fixes everything. I actually thought Tropical Cactus was just taking the piss. Uehh, this Viper and its esoteric rituals.
Anyway, it works now. Thank you for your help.

To repeat my question from another thread, i have the same issue and 2.7 only works for me when the "attach audio effects" option is checked and that introduces quite significant audio lag when skipping tracks.
I also can't seem to get rid of the permanent notification without breaking vipers functionality.
Is there any fix for this? Or a way to properly install 2.5.0.5?

Lol. Forgot to suggest 2.7.1 and then install drivers twice.

I got it working after finding a guide that had to do with audio modification library too. Followed it perfectly and all works. I'll try to find it.

Tried to find that one again, too.
I ended up installing the Audio modification library magisk module, rebooting, deactivating (not uninstalling) that module and then installing the current Viper 2.7.1.6 module.
May have rebooted after that before installing drivers and therefore rebooting again, can't remember though.
But it does work perfectly and the guide did go something like this.
Also possible that a Viper update fixed the issue.

General [Solved][Viper4Android] Somewhat got working

I was in a fight to get V4A to work on my oneplus 9. In the end I did get it somewhat working.
1. Installed JamesDSP https://forum.xda-developers.com/t/jamesdsp-audio-manager-mmt-ex.3607970/
2. Installed V4A version 2.7.2.1 Via Magisk https://github.com/Magisk-Modules-Repo/ViPER4Android-FX
3. Rebooted after doing a cache wipe
Once tried The V4A app will install drivers but not work. will reboot every time i open the app. In all they both operate. I tested by turning off, and on both modules in magisk. They both work/improve the audio. the James DSP works good I can impy Convolvers, DDC's, Profiles wont apply though. I feel like a problem is that it refuses to "ask" get Root permission. Any help would be greatly appreciated.
[edit]
I got it working almost perfect.
Through the same as stated start
1. Reboot into recovery
2. Flash JamesDSP, then wipe cache, mount /sys, flash again, don't wipe cache again
3. Flash V4A, don't wipe cache
4. Flash Audio Modification module for V4A https://github.com/Zackptg5/Audio-Modification-Library
5. Wipe Cache, Reboot
The only down is that V4A app cant change convolers, ect.
JamesDSP changes them all great.
So I can custom change audio lol

Use root explorer go to data/adb/modules/viper. Replace file with this file. https://drive.google.com/file/d/12H0O9ZgzvBIaBAAYKob7CW6JQMOtuXRP/view?usp=drivesdk. Post fs_data_sh.. the one that is left add .bak so it no longer uses. Open viper settings and flip on legacy mode. Reboot. Turn on some tunes all will process and work properly.
