For proper installation and most efficient sound ? system ;

Download Application uninstaller. (like Root Uninstaller)

How to proceed?

Search ? With the Application Uninstaller remove Adapt Sound and SoundAlive.

Reboot your phone ? and goto Equalizer from your Audio ? player which will take you to ViPER4Androidfx and set it as default.

You can now make all your essential changes and enjoy a world ? of music ? blast.

That's what am using right now.

Hit like button ? if i help you in anyway...

[MENTION=7931261]Seagold[/MENTION], you're taking about samsung, right? Which model? I like the connection of V4A+Dolby Atmos - which won't work without SoundAlive.apk, I think...
[Android Apps and Games] JJEgan:
Remove Sound Alive etc.

Does not work for all Samsung or Music Players.

May give multiple error messages of sound componets missing.

Just use JamesDSP. It's built from the ground up and an alternative to Viper4Android. It has a 64 bit driver.
[Android Apps and Games] knpk13:
Does JamesDSP have anything like DDC files? That's the only setting I use on V4A and I couldn't find it on JDSP.

My mistake, I am running 2.6 on my daily:o

I have the following APK for substratum theme.

ViPER4Android FX Substratum Theme 2.0.apk
MD5:70d591461f50f642df1438158e30f193

I do not wish to post it and thereby cause a duplicate, but I would of downloaded it from somewhere here on XDA. I did a quick search and came across the following thread, but did not check if its anywhere on that thread https://xdaforums.com/android/themes/app-viper4android-materialized-t3624655

Hopefully the above and the screenshots below will help you find it

and also see how it looks

Obviously I'm big on dark n teal;)
[Android Apps and Games] Joe199799:
Could I change the teal to any color?

Which substratum themes theme viper 2.7? The only one I know of that individually themes it is ethereal Q
[Android Apps and Games] Zackptg5:
That's for old v4a 2.5 material, not current version. That substratum theme has lots of different accent colors
[Android Apps and Games] Joe199799:
Do you know of any that theme 2.7 other than ethereal Q?
[Android Apps and Games] DiamondJohn:
My mistake, I am running v2.6 on my daily, not v2.7. :o (noted/edited in post above)

I did install 2.7 on my spare running Havoc-OS Pie, and it defaulted to the dark theme.
[Android Apps and Games] knpk13:
2.7 uses whatever theme the system style is set to. Change system style to dark in display settings if anyone wants the dark theme.

If anyone wants a black theme or more info, here's a reminder.

[Android Apps and Games] BadToThePhone:
I'm hoping someone can help me. Just wanted to give some updates. I'm on the LG v20 running stock nougat. I've been testing different Viper4androids and the version that works the best for me is 2.7.0 by [MENTION=9073985]Team_DeWitt[/MENTION]. I've tested 2.7.1 and 2.7.0 works better. With 2.7.0 speakerphone and headphones process fine with every app. The issue is with bluetooth not processing. I've tried using audio modification library and audio compatibility patch with different settings and options and can not get the bluetooth to process. When I am connected to bluetooth V4A does recognize it is bluetooth but doesn't process. The only way to get bluetooth to process is to force close Viper4android and then reopen it and bluetooth would process. Do anyone know why this is and if there is a way for V4a to force restart when connecting to bluetooth or any other way for it to work? And with version 4.3 by [MENTION=6037748]Zackptg5[/MENTION] speakerphone and headphones process fine also. But I can't get bluetooth to process audio either like 2.7.0 If I want it to process audio I have to make a phone call first and hang up and then bluetooth audio processes. I've also tried the audio modification library and audio compatibility patch and they didn't help. Sorry for all of this. Hope someone can help. Thanks

Guys, Viper FX doesn't installing driver. After reboot the driver is working but after second reboot the driver is uninstalling itself. I am using PE CAF on my Poco. Please help!
[Android Apps and Games] Zackptg5:
Search the thread, this has been discussed numerous times
[Android Apps and Games] :
Yes, but I am not understand what I need do: type in terminal "killall -q audioserver" with sudo? Or need to install AML and ACL?

UPD: The terminal helps me, but after reboot same story
[Android Apps and Games] mixlex:
I never had to toggle the audio session switch when switching sources with 2.7. Now with 2.7.1 I need to toggle session switch when changing sources. Just wondering why this is so. 2.7 is definitely a better option for me. Can't be playing with toggle switch while driving. Not complaining, I definitely appreciate the reworked apk. Just saying.
[Android Apps and Games] TheBogeyman:
Would it be possible to add a start script in the app that checks if the drivers could be found and if not run the "su -c killall -q audioserver" command?

Since many users are affected, it would be more convenient than running the command manually after every reboot.

Other than that I use an app called "Boot Shell" which allows running a command on boot. This may be helpful for some users.
[Android Apps and Games] gkornaks:
Hi,

I'm on Xiaomi Mi A2 lite. After installing latest May security patch V4A keeps prompting me to install the driver. Any help appreciated.

Thanks!

Germans.
[Android Apps and Games] Walker Street:
gkornaks, you might need to use the same fix now :

Clear the V4A app's cache or reboot

Run in terminal :

su -c killall -q audioserver

Then run the V4A app

I am also using the app "Boot Shell" to run the terminal command at boot (on TheBogeyman's advice) and following this with automatically starting V4A with the "AutoStarter" app.
[Android Apps and Games] DiamondJohn:
Not sure what your "AutoStarter" app does, but if you already run a script to kill the audio server, would the following work by adding to the end of the first script, thus removing the need for "AutoStarter"

am start -n com.pittvandewitt.viperfx/com.pittvandewitt.viperfx.StartActivity;
[Android Apps and Games] gkornaks:
Thank you! It worked.
[Android Apps and Games] Mint Julep:
Damn...

I tried everything

flashed through magisk, TWRP, get the app try the killall command update busybox...

Nothing work!

Still this annoying "no driver"

Any thoughts?
[Android Apps and Games] DiamondJohn:
A thought would be to let people know which device, ROM, android version, Magisk version and possibly a logcat of the driver install process. One of those may trigger someones previous experience.
[Android Apps and Games] Walker Street:
Yes thanks, I'll try that out.
[Android Apps and Games] Mint Julep:
HI!

You're right sorry.

I use havocOS 2.5 (pie) on galaxy s7 herolte

Magisk 19.2

It seems to be a ROM issue : sound mods don't work on havoc for some reason.
[Android Apps and Games] DiamondJohn:
I have two phones. My daily is running Oreo Havoc-OS, and my test phone is running Havoc-OS Pie (I think I am two builds behind), on an S4 GT-i9506.

The other night I just installed Viper v2.7, and it appears to be working. The only problem I had was that I couldn't find the music player within the ROM, and so installed my favorite (also on my daily), which is Vinyl from F-Droid. On my daily I am running Viper 2.6

I haven't tested it with ear-phones, but it is working over the speaker.:confused: So it appears to be device specific, not ROM.

I don't think this will be the issue, but have you tried switching your SELinux? I know earlier versions had issue with it, but I would assume the Magisk module will correct it in the current version.
[Android Apps and Games] Mint Julep:
It's specific of havoc for this device because Viper works with lineageOs and resurrection remix (both pie) on the same device.
[Android Apps and Games] armando_rod:
Has anyone made it work on Android Q beta 3? Apparently the driver is installed but the app always say "enabled: no"

Edit: solved using version 2.7.0.0. Something is messed up with the driver ibstallation in version 2.7.1.0. It has nothing to do with magisk, I'm running 19.2

Hi, with convolver enabled sound is always delayed. Since I use speaker optimization to get better sound from phone speaker, this sometimes leads to missed notification sound. Do any of you have an advice to reduce convolver delay?
[Android Apps and Games] DiamondJohn:
I am not running v2.7 nor Pie. However, on one of my previous phones (Nougat, Viper v2.5) the ROM did not have the correct allows, so the simple way would of been to set SELinux to Permissive. Instead I extracted the binary from one of the install zips to change SELinux on a running device, and then simply added in the minimum allows (as a boot script) to enable Viper. ie I was running enforcing.
[Android Apps and Games] greyhd:
Works fine here, the only issue is if you use Spotify the effects Don't take effect but that is Spotify's issue. In viper you have to go into options and turn on the "0" effect option.

I'm testing 2.7.1 test version. So far so good. Processing with all music apps, Pandora, Spotify, Amazon, I heart, and music on phone over Bluetooth. I haven't had to use attach audio effects switch at all yet. Maybe the changes will make the switch unnecessary? I will continue testing and see how it goes.

Why both James and viper? Kind of two eq's does the same you know.
[Android Apps and Games] flitzz:
I've been using it with Viper Legacy and both with DDP made the sound richer with Spotify. You can always turn off one or the other and chose what to use separately.

Try dtsx or ultra with one eq instead. See if you achieve. ?

[Android Apps and Games] DoctorGonzo:
Works great overall! Installed on Le Eco Pro 3 with AICP 13.1 (with 5/18/19 weekly build), alongside Ainur Sauron MK III. Echoing other comments in this post, make sure you have disabled or uninstalled 3rd party EQ software (whether it is builtin to your rom or 3rd party music player). Only issue I have had is having to re-enable the bluetooth (through toggling the "attached audio effects" in the settings tab), when connecting and disconnecting from multiple bluetooth devices. Same issue with with official (legacy) version of the app (which required you to toggle power, exit, and toggle power back on).
[Android Apps and Games] madprofessorus:
Thank you, Poweramp didn't work,? I have the 2.5.0.5 , it works
[Android Apps and Games] oviseven666:
Yes, I have tried everything, but the error persists, the driver is never installed and asks me to install it on each restart and when I open the application
[Android Apps and Games] MrBrazil1911:
I used Boot Shell as Walker Street suggested and made two commands. One to kill the audio server and the second one with your code to start Viper. However, it appears Viper is already starting on its own as a notification is present before Boot Shell has run. This causes Viper not to have the driver loaded. If I manually force close Viper and re-open it, the driver is loaded since the killall command was previously run by Boot Shell. Is there a command I can run that will automatically re-start Viper so it will start after the killall command has run or a way to stop Viper from starting on its own at boot so Boot Shell can do it with your command?
[Android Apps and Games] DiamondJohn:
Are you certain there is no overlap in files and config that they change to make them work?

kill $(pidof XXXXX);

Where XXX is the process name. I am actually running v2.6, so my process name is different.

To help with commands, I built a utility https://xdaforums.com/android/apps-games/app-temefi-comprehensive-documentation-t3806260 You fill find the kill commands under:

Application Info / Manage>State>Kill More Apps

Then pop out the menu,

then long press the X button. This will open a search input box.

Type in Viper and click ok

Then Long press the found menu item, which will pop up another options box

Click on "Preview"

The above will show the code to kill the selected process.
[Android Apps and Games] MrBrazil1911:
I appear to be stuck. After Manage>State>Kill More App it opens to the options of Menu Up or Hide Menu. There is an X and I long press it and enter Viper and nothing is found. If I choose Hide Menu, Please Wait... and a dancing banana are there but nothing else ever happens. I granted root access at the beginning, so I'm not sure what else to do now.
[Android Apps and Games] DiamondJohn:
You are rooted?

You have granted root to TeMeFI?

What do you get if you run the following in a shell?

su;
ps -Aw;

If a list of apps does not appear, then there is no point filtering to "Viper"
[Android Apps and Games] MrBrazil1911:
Yes, rooted with Magisk and granted to TeMeFl.

A lot of apps and info comes up in Terminal. I even see one that says process.VIPER4Android.
[Android Apps and Games] Kupaloid:

[Android Apps and Games] Dioser:
For some reason. Poweramp stopped working for me, but I think I bought em all (music players) pi music was working instant, but don't like the design. Eon likewise worked out of the box as well, and like the design way better. I did try several others no luck. But these two sure works here with 2.7.1 ? likewise YouTube music and Spotify.. all runs nicely together. Switching back and forth, no issues.

Start over, uninstall viper and download it from xda forums and open the apk and it will create the Magisk module automatically.

so i switch slot and went to slot a and dirty flashed april update, still no luck so i wiped my device when it prompted me and it booted back

so now i wanted to install magisk and booted twrp and twrp booted but i didnt installed anything and just rebooted to system

and it didnt booted and now i get a prompt saying my device is corrputed before that unlocked bootloader prompt and it is not booting

any help please

Did you do a full clean flash of the April factory image with wiping userdata intact?
[Google Pixel 2 XL Questions & Answers] Prattham:
i did dirty flash but it went to android recovery and from there i did the factory reset beacuse it was not booting
[Google Pixel 2 XL Questions & Answers] ilal2ielli:
Your data was already wiped, so you should just go all the way and do a clean factory image flash. It'll probably fix it.

Cleaned flashed on both slots and worked
[Google Pixel 2 XL Questions & Answers] elliwigy:
typically with that error means your device is failing verification, dm verity, or both. you probably had it disabled but when u dirty flashed it wrote fresh re-enabling dm verity/verificationso when u modified the device with twrp it was corrupted..

next time try to disable verity and verification on both slots and u might avoid a clean flash

How to disable on stock ROM?
[Google Pixel 2 XL Questions & Answers] elliwigy:
if u are unlocked you can do it with fastboot and the vbmeta.img from the stock rom your on..

fastboot flash vbmeta_b vbmeta.img --disable-verity --disable-verification

fastboot flash vbmeta_a vbmeta.img --disable-verity --disable-verification

fastboot reboot

Theres also a file or two probably floating around if u can find it that can be done from root terminal or root shell.. the binary is called avbctl.. i cant recall the commands but if u find it and push to your device just type avbctl and it should list the commands.. its something like avbctl --disable-verity avbctl --disable-verification.. this binary will also let you check if they are already disabled or not..

theres also a zip floating around if u can find it.. this zip is flashed in twrp and will disable them for u

keep in mind if u are not unlocked u probably wont even have the disable commands showing in fastboot.. also, you only really need to disable them if u are getting corrupt errors or boot loops.. of course theres also a chance u have another issue entirely but in my flashing craze majority of time for me disablimg fixes my boot issues after flashing firmwares
[Google Pixel 2 XL Questions & Answers] mac796:
I've had this happened quite a few times it's usually when I go from custom ROM back to stock when I go to update my new month. Almost every time restore a stock backup in TWRP gets me out of it. And if that doesn't work I try flashing stock image to both slots without the w. I'll try disabling that verity thing next time though if I can't get it to work
[Google Pixel 2 XL Questions & Answers] techlogik:
So, tried flashing resurrection Rom. Had some issues. So, ran a Deuce with latest full stock like I always do. After the flash, getting "Your device is corrupt. It can't be trusted and may not work properly." Now in fastboot can't even run Fastboot commands from computer. Not responding at all to anything :(

Any ideas?

Edit:

did some more troubleshooting.

Ran from the zip download:

fastboot flash boot boot.img

fastboot flash dtbo dtbo.img

Then set the fastboot slot a active.

Then was able to boot recovery.img and then reboot.

Somehow the slot must have been changed/corrupt and wouldn't work? Anyway, all working now.
