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.

Good luck!

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.

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!

Worked for me as well! Wondering if this is a recent problem as I've had Viper installed up to a few days ago. Had to install on a new phone, same model.
Anyone got Viper working? I've installed the material one from here, audio compatibility patch etc but it doesn't seem to do anything?
I loaded some profiles into the folders and the app also crashes when I try and load one
About to test that right now.
Use the one in Magisk called Viper4Android FX not the legacy.
This one works for me.
Have been using it since day 1 after installing Magisk. Has been working, the same as the 6T.
yes here is a magisk module of VIPER4Android 2.7.1.0 magisk module i made based on APK so no other special things needed.
Just open app and it will ask for root and install drivers... will auto reboot and done...
download
Has anyone got a profile pack that works with this one?

Hi,
Thank you for the module you have created. I am attempting to use this on my op7p, but it does not appear to enable. I am rooted and used magisk to install the zip, then rebooted, then ran the program to install the driver. The profiles folder for viper is loaded to the root directory. Running audio on my Bluetooth headphones defaults to Dolby Atmos "balanced" mode, which I cannot disable without toggling audio sources. It seems to default into thinking they are wired speakers until I toggle between speakers and Bluetooth. After this, I can disable Atmos processing, but still no luck enabling viper. Additionally, attempting to enable the higher quality codecs in Dev options never takes, they seem to revert to system default as soon as I exit the menu.
Running viper shows "driver enabled: no", and "processing: no". Did I mess up a step of the installation, or is something missing from magisk/viper?

try to go to settings > Attach Audio effects and enable and then disable (while music is playing to see if you can tell a difference)
Hi, thank you for the quick reply. Toggling audio effects doesn't appear to have any audible differences, but if it is on, the status goes to "abnormal" and the audio format is unsupported.
Toggling master limiter enables/disabled driver status, and apparently my music player (pulsar) is not supported or recognized by viper. Using YouTube vanced I am showing that viper is indeed processing, and I can tell what is working or not. Looks like it's time to find another media player :fingers-crossed:
Do I need to do anything to the inbuilt Dolby before installing the V4A mod?
Thank you
Yes mate, go into settings for V4A and enable effects and master limiter. Then change song and you should be good to go. Also, go into the V4A folder. Move all of the files in the DDC-Orig folder and create a new folder called DDC and move the files into there. Now you should be able to use the profiles
I had to install the magisk modual first and then install the apk version from xda labs before it would work.
It now works on Spotify but not on other apps like bandcamp.
I got it working on my oneplus 7 pro by following this video on YouTube.

The thread title says it all. Does anyone know why V4A won't install properly on OB 12? If you install the drivers and reboot, it just asks you to do it all over again on reboot.
Install busybox with magisk, try use v4a legacy version. Try different v4a versions

I discovered the culprit for this. It's AML ( audio modification library) it's simply not compatible with v4a on the newest one plus firmware. As soon as I removed a AML, viper installed
On latest Oxygeon OS 10.3.4 having issues installing ViPER4Android legacy from Magisk.
It keeps asking to reinstall the driver....succeed, reboot...and back to the same message to reinstall the driver.
Does anyone have it working? What did you do?
ViPER4Android 2.7.1 install and Tasker automation
Managed to install the latest ViPER4Android 2.7.1 on Oxygen OS 10.3.4.
Installed the APK which creates a Magisk module and you can then update it from there.
You can find the latest version here: https://labs.xda-developers.com/store/app/com.pittvandewitt.viperfx
Driver installs with no issues and seems to work fine though all profiles got converted to the new format it uses in 2.7.1
Tasker automation also broke since the app commands changed to kill/reload it. For anyone interested, these are the new shell commands to use in Tasker to automate bluetooth profile switching in Tasker.
Code:
cp /sdcard/Android/data/com.pittvandewitt.viperfx/files/Preset/Headphone1/bt_a2dp.xml /data/data/com.pittvandewitt.viperfx/shared_prefs/bt_a2dp.xml
killall process.ViPER4Android
am start -n com.pittvandewitt.viperfx/com.pittvandewitt.viperfx.MainActivity
Launch app: Spotify
Run each as root. Repeat for each device you want it to switch settings for. These actions are activated when a bluetooth headset connects.
Ive tried downloading several different versions of Viper4android and Dolby Atmos and I can't seem to get it to work. My drivers in Viper4Android say Status:Abnormal.
Am I required to set SELinux to permissive if I'm rooted?
My device is rooted and I prefer not to set SElinux to permissive. Is there any way around it?
Will any Viper4Android version(even the latest version) work with lollipop 5.1.1?
Do I need a specific version of Dolby Atmos to work?
I have Magisk installed and tried installing the Audio Compatibility Patch and Audio Modification Library and installing the drivers, then i uninstalled them and reinstalled the drivers but nothing is working. When I try to open the Dolby Atmos app it force closes. The Viper4Andriod app opens fine but it says drivers are Abmornal. This is for my minix box which has a bluetooth speaker connected to it and I'm trying to get better sound coming out of my Bluetooth speaker for watching movies.
I tried using this method also
but the link in the description is not working https://labs.xda-developers.com/store/app/com.pittvandewitt.viperfx so I tried using another version I found online which bundled Viper4android and Dolby Atmos.
