[Q] Using Viper4Android with Poweramp on Stock Lollipop Rom

Hello, I've got a problem. I've rooted my LG G4 and now I´m on stock 10c version, bootloader is locked. I've changed SELinux to permissive and wanted to use Viper4Android with Poweramp. Viper4Android is working, besides I've tried this http://forum.xda-developers.com/lg-g2/general/guide-poweramp-viper4android-lollipop-t3133935 and this http://forum.xda-developers.com/lg-g2/general/guide-how-to-make-viper4android-lollipop-t3075794 and this http://forum.xda-developers.com/showpost.php?p=62107040&postcount=109, but I've not managed to get Viper4Android working with Poweramp. In FX compatible mode, it has just no effect, and in normal mode, it shows "Status: normal" and "Enabled: Yes", but "processing: no" in driver status. In Poweramp, DVT is disabled, in developer options, NuPlayer is disabled. So I have no idea what's wrong with this.
Has anyone an idea?
Edit: I've freezed the stock music app via Titanium Backup, so there should be no equalizer working, I think at least?

Man I m here with you.. I can't get it to work with poweramp either tried all those methods. The funny thing is it works with the stock music player, just not poweramp.
Edit: I tried the method mentioned from the first link that you have posted. This worked for me finally .

Third (manual) method, which might work for other roms and even other phones:
- Download attached zip, extract files
- Using any file explorer (ie: Rootexplorer), go into /system/Priv-app and create a folder called V4A or Viper4Android. Place ViPER4Android_FX_A4.x.apk in this folder. While the folder isn't actually necessary, it's cleaner than just leaving the .apk inside /priv-app/
- Go into /system/media/etc and do a backup of audio_policy.conf
- Open up audio_policy.conf using a text editor, and delete the following code:
Code:
deep_buffer {
sampling_rates 44100|48000
channel_masks AUDIO_CHANNEL_OUT_STEREO
formats AUDIO_FORMAT_PCM_16_BIT
devices AUDIO_DEVICE_OUT_SPEAKER|AUDIO_DEVICE_OUT_EARPIECE |AUDIO_DEVICE_OUT_WIRED_HEADSET|AUDIO_DEVICE_OUT_W IRED_HEADPHONE|AUDIO_DEVICE_OUT_ALL_SCO|AUDIO_DEVI CE_OUT_AUX_DIGITAL|AUDIO_DEVICE_OUT_PROXY|AUDIO_DE VICE_OUT_ANLG_DOCK_HEADSET|AUDIO_DEVICE_OUT_FM|AUD IO_DEVICE_OUT_FM_TX
flags AUDIO_OUTPUT_FLAG_DEEP_BUFFER
}

- Reboot
- Go into Viper settings app
- Install required driver
- Go into poweramp -> settings -> audio -> advanced tweaks -> Disable DVT (Direct volume control)
- Reboot

Yeah, now the first method worked for me finally too, but...! Now Android OS drains significant much more battery than before and that's why it's not a solution for me and I will abstain from using Viper4Android on Stock Rom until my guarantee expires, so I have to wait for more than a year and a half

I dont have this issue. Atleast not yet, were u using the Super high quality more( or something like that)?
also i don't think root voids u r guarantee, but its ur choice

Ok then I don't know what I am doing wrong... No I have just the High Quality Mode. Auf oh I have root but when I don't have guarantee any more, I consider to install another ROM
Respectively, on MM it's not possible to root withoout unlocking bootloader :/

Use Link2SD and convert V4A to a System App. Now it should work fine with Poweramp.

Can't get Viper4Android working on my M8 running GPE 6.0 ROM

I'm struggling with installing Viper4Android on my device.
I tried installing using either the apk from the original thread (http://forum.xda-developers.com/showthread.php?t=2191223). It install successfully but I keep getting a driver install prompt, after installing the driver and rebooting.
Things I already tried without success:
- Installed BusyBox with BusyBox app (https://play.google.com/store/apps/details?id=ru.meefik.busybox)
- Setting the SELinux mode to permissive using SELinuxModeChanger app (http://forum.xda-developers.com/showthread.php?t=2524485)
- Setting the SELinux mode to permissive using flashable permissive.zip
- Installing the apk from the Material design Viper4Android thread (http://forum.xda-developers.com/android/software/app-material-viper4android-2-3-4-0u-t3190352)
- Flashing the .zip from the same thread.
I'm currently running Android 6.0 GPE, flashable version (http://forum.xda-developers.com/showthread.php?t=2708589)
Root access is granted through SuperSU, so no problem on that matter I suppose.

2. With a File Manager(Solid Explorer Recommended) locate " /system/etc/htc_audio_effects.conf" and rename "htc_audio_effects.conf" to "htc_audio_effects.bak" (Renaming this file will make it inactive but while keeping it backed up just in case this doesn't work for you, however it appears this file is not needed as no negative effects occur, and this should fix V4A.)
3. Reboot Device.
And if this doesn't work I thin you should grant storage permission for V4A under settings. I hope I can help you!

Viper4Android MTCD Discussion

Okay wanted to make a thread specifically for sharing V4a settings profiles irs etc
v4a is the best sound mod for our units since we don't have to make hardware modifications to be able to have subwoofer controls etc.
This thread is to serve the purpose of creating a space for those using V4A with car audio systems as the threads for V4a don't really address car audio much.
Before I install V4a I flash the XtremeBeats Aural Maximizer 2 zip https://forum.xda-developers.com/showthread.php?t=2634729
for V4a I use ARISE Sound Systems zip package, which includes V4a and other sound add-ons, I flash it via FlashFire
https://forum.xda-developers.com/android/software/r-s-e-sound-systems-auditory-research-t3379709
Sometimes it works better if you extract the v4arise 2.3.4.0 version (that's the best one due to the sound driver is superior than 2.5.0.5 or 2.4.0.1)
I have 13 kicker speakers including a 10'' kicker free air sub.
Here are my Settings for V4A
Enable & Force Enable are both checked
Playback Gain Control is enabled, effect is sight, strength is 4x, Max Output is at -3db
Spectrum Extension is enabled, strength is at .5 (great for spotify streaming)
Convolver - IRS is Samsung SoundAlive Clarity - Cross Channel is @ 15%
Dynamic System enabled , device is high end headphone v2 , dynamic bass @ 15%
Viper clarity enabled , cclarity mode is natural, set at 6db
All the IRS files I have loaded are located in zip attachment.
It sounds amazing now
I am playing around with listening device settings to see if i can find a compatible setting too

First check your MCU and Android version from manufacturer is up-to-date - as some introduced sub control in updates. E.g. JY from MCU v.1.90

running 2.0-1 MCU and sub controls do not work.
Hardware modifications are needed for them to work from all my research so far, unless you have something up ya sleeve

Works just fine in my experience on JY-UL135. UI provides sub control which works with the correct MCU - JY 1.90 or greater. Nothing wrong with hardware control either - on these units if sub control isnt supported by the MCU, v4a control is limited to android apps, i.e. radio unaffected.
Please share your research.

Regardless of the MCU (i have a gs unit), the sub controls do not work period.
Maybe it's due to my setup, i have a 16 channel, harmon kardon amplifier...

Does flash fire depend on Google play services or similar? I was able to install the apk, however when selecting the flash fire icon, it would try to open the program and then immediately quit.
Tried both .24 and .2 flash fire.
I have the MTCD_KGL with the malaysak rom flashed

Thnx, I'm gonna try it tomorrow combined with Malaysk V10 rom.

has anyone found a viper ddc to work with car speakers?

I have to open viper every time I turn on my car to get the audio processing to kick in, once I do that it works just fine, until I turn off the car and turn it on again. Do I need to convert it to a system app for it to start automatically? Have the Bonroad 7" Intel Sofia off aliexpress.

If you install it as a user app, and lock effect mode and show notification it will process normally upon boot.
When you flash it via fireflash for some reason it then does not process until you open it and uncheck and re-check enable.

make sure you have busybox installed and updated too!

has anyone found any good IRS files that they can recommend? i'm always looking for more.

has anyone played with any more IRS files or setups?

Does flashing ARISE zip with FlashFire installs ALL the modules? I only need V4A

The Aroma installer gives you the options to install whatever you want.
I go with the 2.3.4.0 version because of the superior audio driver.

[Guide][CM13] ViPER4Android 2.5.0.5

Enforcing is set by default on CM 13 so I tried to find some fixes trying to make it work then I got lucky.
If you want the new version of ViPER4Android you can download it here.
Firstly I advice you to install ViPER first (Do not open it yet) then go to Developer Options and disable the root access after that you can reboot to recovery and flash this and here is the link where the flashable zip came from.
Screenshot Here
You can enable the root access after boot and install the audio drivers. If you want to place ViPER4Android on the system you can use Lucky Patcher. (Trust me it helps)
Thanks to zhuhang for the app and AntonPanos for the flashable zip and lastly mobiusm.

[Guide] How to Revive You Beloved Vince?

Disclaimer: I am not an android developer, neither do I possess any of the software mentioned in this guide. Thanks must be given to the developers in their own threads. I am just a ‘tester’ if there is such a thing.
​What this guide provides:
Update Vince to smoothest android 10.
Tweak in-call volume.
Tweak sound quality.
Get the best performance.
Longer battery life.
​Xiaomi has abandoned Vince after the miui-11 update, which was worse than expected. Fortunately, the hardware of Vince is great and it can be revived if you want; just follow me.
I guess you already unlocked the bootloader (if you haven't, it's quite easy just google it) and flashed some custom rom, OrangesFox is great.
​
What do we need?
Custom recovery: OrangeFox is the best for Miui devices.
Custom rom: ionOS, from here, is great and smooth. I recommend ionOS with GApps version 2.7a.
Custom kernel: it is just an update of the kernel used in ionOS (dark ages último).
Magisk: I recommend latest magisk 21.4.
NFS Injector module from here.
​
Update to android 10:
reboot to recovery.
backup system, data, and vendor ‘optional’.
wipe everything except external sd.
reboot recovery.
flash ionOS, reboot to system (don't flash magisk), and set up your phone.
after finishing the setup, reboot into recovery again.
now flash Dark-Ages-último.
wipe cache and Dalvik.
reboot to system.
​
Root:
reboot into recovery.
flash latest magisk
wipe caches then reboot system
​
Tweak Speaker Sound:
Android 10 custom roms, usually, provide a bad sound quality experience. Following tweaks makes sound volume higher and quality better:
select modules tab in magisk manager.
find and install busybox for android NDK module.
find and install Ainur audio mod.
install audio compatibility batch mod
install audio modification library.
reboot the device
install latest viper4android fx from apkmirror, open the app, provide root privilege and wait for drivers to install.
after your device reboots, open viper4android, in settings select legacy mode.
That's it! now use V4A options and equalizer to optimize the sounds as you like.
Tweak ear speaker volume during calls:
Download any root explorer, like solid explorer or root explorer.
open root explorer app ➩ select root tab ➩ and provide root permission.
navigate to vendor ➩ etc ➩ swipe down to (mixers_paths.xml) and open it with a text editor.
search for RX1 Digital Volume, in the 2 results change Volume= “84” to a higher value (94 is high enough)
save and reboot the phone.
Tweak power and performance:
in magisk manager, select the modules tab.
select install from storage.
select NFS Injector mod.
wait for the installation to finish.
reboot device.
Now everything is working great

Is there green tint issue in whatsapp camera present in that rom?
