[Q] ViPER4Android works in Beanstalk?

Hello everyone. I'm new here and sorry for my bad English I'm using google tratuctor
Well as the title says i have a dude with V4A, i installed BeanStalk ROM in my atrix HD and its work fine i not have problems with nothing for now, but my only issue is V4A i'm install it, make my config but when even if I have activated not seem to work either with the default player(by the way, i use poweramp and in the stock rom V4A works with no problem ). I read that the reason may be the kernel and i want to know if there is way to make it work without changing the kernel.
EDIT: Keep looking after finally worked, i just had to put the FX effect in "compatible" and enable the FX button in poweramp.

[HOW-TO] Installing Viper4Android (V4A) Audio on a Lollipop Tab S [Updated May 12th]

UPDATED: Updated V4A flash file to Viper4Android v2.4.0.1 and added notes about the TabS AOSP Marshmallow custom ROM compatibility by Schischu.
The obligatory warning:
"I take no responsibility for what happens to your device if you follow this guide. This procedure works with multiple Audio/Video apps. It should work for any Samsung device, but I can't confirm, so feedback please if it works for your device."
- 3DSammy
Root with SuperSU is required either using a standard rooting method that trips KNOX or following this guide "[GUIDE] How to root without tripping knox - Kitkat and Lollipop, Locked bootloader" by ashyx. Having SuperSU installed and functioning is essential to get around Viper4Android's need for SELinux permissive mode which is not possible when you are using the Samsung stock firmware.
As of June 8th maximumentropy posted a method to use SuperSU to work around Viper4Android's need for SELinux permissive mode. This requirement was problematic on Samsung devices where the SELinux mode changer app did not work with the Samsung stock firmware.
The instructions and flash files below will allow both custom ROM and rooted stock ROM devices to install Viper4Android, an amazing audio replacement.
Note: V4A and the included flash file works with the AOSP Marshmallow custom ROM compatibility by Schischu. Any of the SoundAlive comments below can be ignored for this custom ROM.
Steps:
1) Download the two flash files "ViPER4Android-supolicy.zip" and "LolliViPER_TAB_S.zip" (at the bottom of this post)
2) Flash ViPER4Android-supolicy.zip and LolliViPER_TAB_S.zip with FlashFire or a Custom Recovery (e.g. TWRP) of your choice.
3) If you want Spotify to work and maybe other audio/video apps then Samsung's "SoundAlive" must be removed or disabled. Options:
Backup then freeze or delete "SoundAlive 2.0" with Titanium Backup
Backup then delete the "/system/priv-app/SoundAlive_Tablet_20" directory with a File Manager that has RW "/system" privileges
Remove "SoundAlive" with an app like "System Remover app" found on the Playstore
4) Reboot your device and then start Viper4AndroidFX and install its drivers when prompted then reboot once more
5) Start the Viper4AndroidFX app and configure audio for the device speakers/headset/bluetooth as desired. Please refer to Viper4Android XDA forum for details about the extensive options.
NOTES:
Be aware that if you do not disable/remove SoundAlive then Spotify will disable V4A until the next device reboot. Causing confusion about whether V4A is actually working reliably. Other audio apps may also demonstrate this tendency.
If you check the V4A driver status and audio is not playing the status will show "Processing: No" that should change to "Yes" when audio is playing and V4A is working correctly.
A Rule-of-Thumb with V4A is to make sure to turn off any Audio/Video player app's specific equalizers, gain controls, audio effects, ... etc, as they interfere with Viper4Android. If you still cannot get Viper4Android working with a specific app, that's not listed in this thread, then search first then if necessary ask on the V4A's XDA forum.
So far the following Audio/Video apps have been successfully tested with V4A:
Neutron audio player (Settings and uncheck Equalizer;Sound Sound;DSP-Effects->Surround Sound;Relay Gain;Normalization)
MX Player Pro (Settings->Audio->Volume Boost unchecked)
Spotify (If it is working properly the Spotify->Settings->Equalizer will directly display the V4A app)
TuneIn Radio
Google Music Player
PowerAmp (PowerAmp Settings->Advanced->Uncheck everything)
YouTube
ViralPro (a YouTube alternative)
Apps that do not work with V4A (likely due to the removal of "SoundAlive"):
Samsung's "Music" app (still plays audio but not by utilizing V4A processing)
Please post any apps not mentioned here, which you either get working or that have problems with after checking the V4A XDA forum.
If you have SuperSU working and have never tried V4A do so and you ears with thank you!

Hi and thanks a lot for helping others out with the notoriously difficult to install viper app.
I presume the supolicy zip is intended as an alternative to setting selinux permissive. Any negatives to using one method over the other?
Also, can you please explain what your application zip does exactly. Does it just install the original viper as a system application or did you make any other modifications?
Thanks!

Either method of getting V4A permissive mode will work but if you rooted and maintained KNOX the stock bootloader blocks SELinux from setting permissive mode so the supolicy is your only alternative. Besides I read a comment from Chainfire who indicates that using permissive mode system wide is poor security practice. On my Nexus 5 which is running marshmallow I found all I needed was two supolicies to get all my root apps running and they were for V4A and stickmount.
The supplied V4A flash file installs V4A in /system/priv-app, sets permissions and attempts to delete two apps that the stock Samsung firmware does not have. Those audio apps are in the Google stock firmware and do no harm as there is nothing to delete. The flash file is based off one for V4A on a Nexus 5. I choose to not delete the Samsung audio app as some people may want to back it up, besides I documented three ways to deal with that app.
I hope you enjoy V4A.

Working perfectly in Galaxy Alpha (g850m - Exynos) with enabled root and native kernel, including the Mix Radio (without special settings).
Thank you so much you saved my travels to work !!!

Does V4A not work on KitKat? I decided to downgrade back to KitKat but can't get it to work.

Yes the app works on KitKat but the directory structure for apps on /system changed. I'd suggest going to the ViPER4Android XDA forum and searching for KitKat installs. That forum link is in the OP (first post).

viper4droid not working

can any one tell me viper4droid is not working in my custom rom resurrection remix 6.0.it is in selinux permissive mode.in viper4droid i tried forcing it but nothing actually happens.I only able to use viper4droid setting but it does not change sound quality or u can say its not working when i off it or not no sound change.

The sound quality change is minimal really. Not even really noticeable. However, when you play with the EQ and other settings, you can notice a difference. I like bass so I boost the bass by as much as 15db and it's awesome. Works great. But I am also not using the rr ROM. I'm using computer Creek's lollipop ROM. Same thing though.

To test if it is working, play some music and then go to the viper4android app -> settings menu -> Driver Status. If processing = yes, it's working.

What app are you using to play music?
Also, there are a couple versions of v4a floating around, and some work better than others. When I was using RR 6.0, I used the ViperAtmos 5.5 Sony Beats Edition from this thread: http://forum.xda-developers.com/android/software/viperaudio-viperatmos-3-8-sq-driver-t3289075

I've been using that version of viper since I got the phone and haven't run into any issues. I do however also have the audio modification library and audio compatibility patch modules installed as well. If those don't help, then I think there is a larger issue.
PS - I've used both the latest stable and the canary Magisk builds without issues.

Which kernel are you using? I'm using ElementalX 1.05.
Tried with audio modification library and compatibily patch modules but didn't work. Everytime i start the google camera, it crashes.

Ok, so... same as me.
Really, i don't know where to start. I've flashed stock rom wiping everything some days ago. So, my phone is clean. I've the latest Magisk stable and elementalx 1.05.
All i can do is try to dirty flash stock rom again and install twrp, magisk and elementalx and try another time.
About audio compatibily patch, there are really too many options and i don't know where to start to install it correctly..... but i don't think google camera crashes because of that......
Same problem if i install Viper4Android FX Legacy module.

I would be surprised if the audio compatibility patch caused an issue too. Honestly I had forgotten about the initial options that I had to choose when I installed it. I just uninstalled it and reinstalled it and only chose the "notification remover" option and then opted out of the lib use (last option). I use the headphone jack, so I don't need a USB DAC (does this phone even have one?), nor do I use Spotify, etc.
However, it is important to install the audio modification library last. It should find both the Audio Compatibility Patch as well as Viper4Android and patch both to work together. I might suggest that you uninstall it, reboot, and reinstall it to ensure it is actually patching both audio modification. Also, make sure the driver is actually installed in Viper if you end up reinstalling any of these mods as you might find that the driver isn't actually installed. It's a long shot, but perhaps that would fix your issue.
I'm also using the leaked camera version 6.3.017.253834016 currently (because it has the night sight setting as a main option instead of buried in the "more" settings). But this really shouldn't matter and the stock camera app worked just fine too. Viper4Android is always one of the first mods I install on a phone and it has never given me a problem on my 3a XL or caused the camera to stop working.

Tried exactly what you said. Same issue, Google Camera crashes on start. Every V4A version i tried, same thing.... Well, i don't know what to try more..... Asked on official V4A thread but no answer. Is there any way to provide logs to discover what happen?
EDIT: I've attached a logcat, if you know what could be the problem i will be happy

Dirty flashed August factory image, Elementalx, TWRP and Magisk. Same issue. Anyone who can help me taking a look at the logs?

Im on 2.5.0.5 and i have no issues so far with the camera app.
The only issue that i have is that v4a is marked as harmful by Google protect. Anyone else?

Pixel 2 xl user here with the latest viper4android on android 10, same camera app is crashing on me
stock 10 with sultan kernel installed and magisk 20.1

I've never had any real issues getting Viper4Android to work on Android 10, but I understand it is a common issue. Here is a Pixel 4 thread on installing Viper4Android on Android 10 and how they got it to work. The fact that it is on a Pixel 4 device is irrelevant. Perhaps this can help you get the driver installed.
PS - I should mention that I already was using the audio compatibility module and the audio modification module prior to moving to Android 10, so it is quite possible that is why I never experienced any issues.
