Another way; any recovery. Click update or whatever it is to get to adb sideload. Then just and adb push your folder to /datalapp whatever
Another way; same as above use adb push just while booted.
Does anyone here use YouTube Vanced and YouTube Music Vanced? Any idea why Viper4Android only gets hooked by YouTube Music Vanced and Spotify, and not by YouTube Vanced, Poweramp, SoundCloud, etc.?
When I close Spotify, it releases Viper, but YouTube Music Vanced does not. I have to force close Viper for YM Vanced to release it, and I get a persistent notification until I do.

do you get the same hissing sound when you turn Viper off, and keep the volume levels the same?
Same error for me. Downloaded the file from this (https://forum.xda-developers.com/t/...ew-features-7-0-support.2191223/post-87109719) post and installed it with Magisk.
Device: OnePlus 8 Pro, OxygenOS IN2023_11_C.33 (Android 12)
Magisk v25.2
I hade the same Problem with my Xperia 5III. You Must Set your Kernel to permissive to work. But after Every restart you Must Set the Kernel to permissive. For me was this the only solution 
Sorry for my Bad english

I'm posting my crib notes below on how to get Viper4Android to work with Selunux on all modern android devices.
###Install Guide###
1) Install 1_Audio_Modification_Library-v3.5(54).zip, enable module, reboot
2) Install 2_Audio_Compatibility_Patch-UPDATE.zip, enable module with options;
Up
Down

Down
Up
Reboot
3) Install 3_Viper4Android.apk, then open app, then install driver/magisk module, enable, reboot
4) Open Magisk and uninstall module 1_Audio_Modification_Library-v3.5(54).zip, reboot
5) Open Viper4Android app, settings, enable "Legacy Mode"
6) from adb shell, push presets to device
7) adb push com.pittvandewitt.viperfx /sdcard
8) Use root explorer for example and manuall move com.pittvandewitt.viperfx to /Android/data/ and overite if necessary
7) Open Viper4Android and select desired preset from note icon at top of app
**Don't skip steps 1-4, as ludicrous as they may appear, they are crucial to getting it to work!

I've been messing with this for a while. I figured out why it won't work, but I don't have a solution yet... maybe someone on this thread can help.
Every version of Android thus far has loaded audio effects from /vendor/lib/soundfx. Android 13, however, apparently loads the audio effects libs from /vendor/lib64/soundfx. While audio_effects.xml may look identical, the default path is lib64 instead of lib.
V4A only provides /vendor/lib/soundfx/libv4a_fx.so, so when EffectsFactoryConfigLoader starts parsing audio_effects.xml, it can't find libv4a_fx.so because it's looking for it in /vendor/lib64/soundfx (logcat gives...)
(
09-24 01:32:51.487 2648 2648 E EffectsFactoryConfigLoader: Could not find library in effect directories: libv4a_fx.so
)
You can *find* libv4a_fx.so by changing the patch in the module's install.sh to
sed -i "/<libraries>/ a\ <library name=\"v4a_fx\" path=\"..\/..\/lib\/soundfx\/libv4a_fx.so\"\/>" $AUDIO_EFFECTS_FILE
but this only works to find it, not open it (logcat gives....)
(
09-25 02:53:20.184 841 875 E EffectsFactoryConfigLoader: Could not dlopen library /vendor/lib64/soundfx/../../lib/soundfx/libv4a_fx.so: dlopen failed: "/vendor/lib/soundfx/libv4a_fx.so" is 32-bit instead of 64-bit
)
The change to looking for audio effects libs in /vendor/lib64/soundfx matters because lib64 is full of 64-bit *.so files, whereas lib is full of 32-bit, and apparently the audio effects are being run as 64-bit binaries now.
So where I've gotten is how to find and try to open libv4a_fx.so. Where I'm stuck is how to actually open it.... I feel like there has to be a way to run just that one audio effect as 32-bit, but I have no idea how to do it yet
Try solid explorer. Only one I could get to let me access system partition
Here's a newer improved installer for Magisk that fixes most of the current problems. Just install it with Magisk and reboot. The current update didn't work for me though, I hope future updates will fix that but by all means try it:

ViPER4Android FX
FX is the main control panel of ViPER’s Audio with all popular ViPER’s Audio settings.
ViPER4Android XHiFi (Stopped)
XHiFi has less settings compare to FX. It has superior audio reconstruction which mainly used for restoring lossy audio quality.
FX Key Features
★ NEW: FET Compressor ★
New compressor / limiter simulating operation of FET circuits.
★ NEW: Quad-Channel Convolver ★
IRS support extends to 4-channels. *Requires special IRS files*
★ AnalogX ★
Richer and warmer sound by simulating the sound signature of pure class A amplifier. *v2.4.x and above+*
★ ViPER-DDC (Now Cuztomizable!) ★
Enjoy near HIFI sound on your headphones. *Not all models supported*
★ Spectrum Extension ★
Make your music sound lossless with enhanced high frequencies.
★ x86 Platform Support ★
Viper4Android supports x86 (Atom/Core i3/i5/i7) platforms.
★ USB/Dock effect Support ★
ViPER4Android supports USB/Dock audio output.
★ Speaker Optimization ★
First effect for speakers. Try it yourself.
★ Channel Pan ★
Controls left/right channel output. Its not very useful unless your headphone is imbalance or faulty one side. It will be a cure for you.
★ Differential Surround / Haas Effect ★
This is an old feature which ViPER520 had removed from FX in early days.
But after many users requesting it, ViPER520 bring it back to FX
More info on Haas Effect: http://www.mixcoach.com/creating-depth-the-haas-effect-2/
★ ViPER Fidelity Control ★
★ ViPER Bass ★
With different bass modes, you can have greater bass experience than before!
★ ViPER Clarity ★
With the latest Clarity mode selection, you can balance up heavy bass with high clarity audio that you can never imagine before!
★ Headphone Surround+ (VHS+) ★
With this VHS+, V4A made its way to achieve great surround technologies for Android.
★ Auditory System Protection (Cure Tech+) ★
With normal audio system, listening for more than three hours will feel fatigue, dizzy, tinnitus, irritated and other symptoms.
This is a normal reaction, heavy bass and high volume could cause permanent damage to the human auditory system, but other phenomena can restore through resting.
Viper as a listening experience professional will not ignore this problem. Therefore put a lot of effort to study how to make a "Healing" sound technology, just a small success. But thinking on how to let users experience it.
★ Convolver ★
When an Impulse Response Sample(IRS) is loaded, V4A will process the sound to show the same characteristics of the loaded sample. Through Convolution, samples with effects such as equalizer, surround, reverberation, tube etc can be loaded.
Download and extract IRS files to <storage>/ViPER4Android/Kernel/<paste files here>
★ FX Compatible Mode (Only in 4.x) ★
Compatible Mode supports large variety of music players and the players' own EQ/sound effects (system-provided/third party)
Therefore, you don't have to select V4A in Sound Settings > Music Effects, choose anything other than V4A. Just run V4A app and the effects will be working with anything else.
1. In option, switch to Compatible Mode. Reboot, done.
2. In Sound Settings > Music Effects, choose other than V4A.
3. Run V4A app and configure the settings then the effects will work together with the one you chose in Sound Settings.
