Viper4android

I went back to using KitKat bc I was having issues with viper4android on Lollipop. Now I get notified that the driver failed to install. Can someone please tell me how to fix this? I'm rooted and I have busybox and supersu installed.

Same here. First I was on Lollipop and the drivers would install, but the effects wouldnt work. Back to KK and now it's saying that the Busybox installation found on my device does not work.

I went back to Lollipop and it works now. Follow these steps:
To anyone on this rom who wants the instructions to install viper its very simple. Go here and download the GalaxyMod V2. Flash it through flashfire. Then go here and download Viper4Android or use standard from their site. Install viper like normal, choose your driver and reboot. After reboot go into poweramp and go to settings - audio - advanced tweaks - and uncheck directly control volume, and directly control bluetooth volume. Also make sure MusicFX is unchecked and all the equalizers are off so not to interfere with Vipers Sound. Open viper and click driver status and you should see that it is supported and processing.
I still install the ViperSU policy just in case I have any issues.

@dkeepitabuck @jwilla11
You also have to edit the following lines in /system/build.prop
Ipa.decode=true to lpa.decode=false
tunnel.decode=true to tunnel.decode=false
lpa.use-stagefright=true to lpa.use-stagefright=false

I did everything you guys said except install the ViperSU policy, and it didn't work (V4A driver installed, but status was abnormal). Then I installed the ViperSU policy zip through Flashfire and now V4A works! Thanks so much. I don't know if editing build.prop is necessary, but I did it just in case. I now know that installing the ViperSU policy zip is necessary.
To the part about Poweramp: I use Walkman as my music player, which works fine with V4A. I just went into my application manager and disabled MusicFX.
To the OP, I didn't know how to edit build.prop until now, so in case you don't know, here's how:
1. download ES File Explorer.
2. click the symbol in the top left to pull up more options.
3. scroll down to Root Explorer and tap on it to turn it on.
4. find build.prop in system folder, tap on it, choose open with ES Note Editor, and edit in what the guy above said.

How did you install the viper4android via apk or you flashed from recovery?

In order to install ViPER4Android, you'll need your system to be properly rooted, BusyBox must be installed, and SELinux Mode must be "Permissive".
I recommend this BusyBox installer, and you can get SELinux Mode Changer from here.
Then, after everything is properly set up, you must also disable your ROM (e.g. CyanogenMod-based ROMs' AudioFX)and/or player (e.g. Poweramp's equalizer)'s built-in equalizer, and switch ViPER4Android's FX Compatible mode from "Normal" to "Compatible".

I was able to make V4A work on my Moto X 2014 with a fix.
If you do not have Busybox or permissive SELinux, follow the instructions our mate's posted above:

After Busybox installed and SELinux on permissive, you flash the Viper zip and install the driver. Right after that you open a root enabled file manager and find system>vendor>etc. You'll see an audio_effects.conf.
(I suggest making a safe copy of this file).
Rename the original audio_effects.conf to audio_effects.bak.
Save and reboot. Now try using v4a again.

Was this procedure required for V4A to work on your Victara? Mine worked in every ROM I tested (all Marshmallow-based) by following the steps you quoted.

Yes. I was only able to enjoy v4a after this procedure.

It's worth pointing out that V4A is going to F up your Moto Voice

Popping into this thread real quick to provide some info,
Using compatibility mode with V4A is bad news, causes extra battery drain and problems with some apps.
For every single rom and device I've used 5.0+ I've followed the same procedure to install V4A, without using compatibility mode, without having to delete a file every time, etc.
Flash the "lolliviper" zip attached to this OP.
Followed by the "Build.Prop-Tweaks" and "Soundfix-LibFiles" attached to this post.
You'll also need a way of setting selinux to permissive after every boot if you're using CM or something else with selinux set to enforced. Something like SELinuxModeChanger available here will work.
If you don't have busybox installed, V4A will tell you and help you install it.
The V4A version included in the "lolliviper" zip is not the newest , you'll need to "Check Update" via the 3 dot menu and install the latest apk.
After all this, install the driver via the V4A app, reboot, and you're golden.

Didn't know that. I was only able to set v4a on a custom ROM, so that ship was long gone hahaha
it just stops working?

Actually it still "works" because it detects your launch phrase, but after that, half of the time it just hangs without hearing your command. Sometimes it'll randomly work, but it was too much of a botch to keep it that way. I've now resorted to Noozxoide Pro: it's still a system-wide mod with modes for headset, speaker and BT, but it's installed as a "standard" app, it doesn't mess with your system and it sounds boss!

I ran across this link on a similar search on the google machine, and it made V4A installation a breeze. No manual messing with kernel settings and whatnot: http://forum.xda-developers.com/android/software/viperaudio-viperatmos-3-8-sq-driver-t3289075
Battery life has been fine running this for about a week. I don't use Moto Voice so can't comment on that.

THANKS

Thanks a lot, I was already discouraged, tried several versions of viper, on diferent roms, this was the only solution, but is necessary to remember that for this file to appear in the folder, you need to open the application and save a profile, even if empty, without it you can not find the file audio_effects

If u root ur device using magisk, u can install viper magisk module...it works fine on android 6.0 with selinux enforcing..

ViperFX

Now we have root with a couple of already patched magisks....I'd like to get ViperFX working. Driver continuesly installs. I've tried compatible mode too to no avail.
I downloaded the Legacy version, will try the "newer" version to see if that works. Will report back.

I was able to get Viper4Android (XDA version) working on my 4 XL with Audio Modification Library from Magisk Manager.
Here's what I did to get it working:
-Install Viper from XDA (don't launch Viper just yet)
-Install Audio Modification Library from Magisk Manager (don't reboot!)
-NOW, launch the Viper apk you just installed, grant Viper superuser access, and then your device should automatically reboot
-Once rebooted, open up Viper again, it may ask you to install the driver again, go ahead and install (This took me 3 reboots until Viper finally kicked in)
-You will know viper is up and running right after reboot when you see a viper logo in your notification!
-Enjoy
EDIT: The following steps above doesn't necessarily quite get system wide equalization working. After a few days of testing and additional tweaking, here are a new set of instructions that installs Viper to allow system wide equalization except one thing, Google Maps navigation audio. I can not figure out for the life of me how to get this working so if anyone does happen to get theirs working on the 4 XL, PLEASE let me know. I would greatly appreciate it!
If you're like me and am just used to defaulting to Google Maps, a little workaround is to change the navigation audio to "softer" in Maps settings to help with the extreme audio transitions when viper stops processing when the next turn direction is being played and then starts processing right after. Not really a full solution, but still not the end of the world.
This time, you will need Audio Modification Library and Audio Compatibility Patch.
Here it is:
1. Install Viper from XDA (don't launch Viper just yet)
2. Install Audio Modification Library from Magisk Manager (don't reboot!)
3. NOW, launch the Viper apk you just installed, grant Viper superuser access, and then your device should automatically reboot
4. Once rebooted, open up Viper again, it may ask you to install the driver again, go ahead and install (This took me 3 reboots until Viper finally kicked in)
4a. You will know viper is up and running right after reboot when you see a viper logo in your notification!
5. Go back to Magisk Manager and now install Audio Compatibility Patch
5a. Select NO (volume down) on audio_policy, then PATCH (new logic) (volume up)
5b. The step below is optional but if you want to get rid of the "ducking" sound when a notification sound pops in, then do the following OTHERWISE just select YES (volume up):
-- Select NO (volume down) on notification_helper remover, then REMOVE notification_helper EFFECT (volume up)
5c. usb policy patching you can select YES (volume up) [I don't use any usb dacs so if your Viper installation does have issues with your usb then you may want to tinker around this area]
5d. Select YES (volume up) for lib workaround
5e. Go ahead and reboot
6. Enjoy!

Just grab the latest from XDA labs, version 2.7 I think. When you open it it'll ask to install the driver and reboot. It takes like 3 or 4 times for it to take for some reason. It DOES work though. I have it installed without issue on mine. You don't need anything but the app with this app version.

Yep, it works. Nice highs and bass is what I needed.

Is anyone having difficulty with the Viper effects stop working when using google maps navigation? Whenever google starts talking, Viper stops processing and continues to stop processing until I manually restart the phone.

Noob question, viper works great but doesn't process Spotify. What is the newest trick to get that working M I have tried compatibility mode as well.

my phone feels very laggy after doing this anyone else

I can't get the audio quality I had on my S8+. I can not figure I out. I followed the OP. MY AIRPODS even maxed volume are so low for phone calls, Pandora is slightly better. The phone speaker blasts sounds. Ideas?

Trying to install Viper4Android, driver install fails (via magisk)

I've tried installing the driver multiple times and can't seem to make it work at all. The only method I've not been able to accomplish is renaming audio_effects.conf to audio_effects.conf.bak as has been recommended for other phones. For some reason, this file will not rename.
it would seem the file is set to be unwritable (I'm not familiar with linux permissions like this, so maybe that can be fixed somehow?). At the very least, Solid Explorer isn't able to do the job, and can't change the rw perms either, as the operation just fails. (I have got selinuxmodechanger changed to permissive and after reboot, but no change here either)
Any other ideas?

Well, for anyone else wanting to know how to make this work, follow this guide here: https://thedroidarena.com/install-viper4android-android-10-q/
Don't use the magisk module for V4A, it doesn't work.
Works great for me now!

I'm using it it works perfect but you have to use the new version not the older one

Do you still have that apk lying around? XDA Labs does not appear to be working ATM.

I saw that, didn't really know what it did. I'll check it out.

Nothing in JamesDSP is doing anything for me on Speakers, Headphones, or Bluetooth. I think that this may beacause of my failed install of V4A rootless (might work if I had the APK?). Any ideas if this is the problem? If It is, do you know how I might uninstall V4A?

If rooted, try installing latest V4A directly from here (https://labs.xda-developers.com/store/app/com.pittvandewitt.viperfx) rather than via Magisk.
I prefer older V4A versions, having tried above.
My preferred V4A is 2.5.0.5 (found in App folder in following .zip from here: https://androidfilehost.com/?fid=673368273298920860)
1. Ensure on latest BusyBox.
2. Install latest V4A from Magisk & download driver, device will auto-restart.
3. Uninstall this latest V4A (don't delete data or cache).
4. Install V4A 2.5.0.5 .apk from above link. Don't open app yet.
5. From Magisk, install Audio Modification Library (choose relevant options). Restart device.
6. Additionally, Magisk install Audio Compatibility Patch. Restart device.
7. Ensure V4A settings FX compatible mode option = Normal.
(Don't optmise V4A in battery settings).
Noticeable improvement in speaker volume (I don't play over BT or headphones, so cannot comment).

I uninstalled everythingg I had installed up to that point (everything I could at least), and followed the instructions step by step. Still getting abnormal in the V4A app (at least the app looks cooler now : P). I really don't know what is going on at this point. I might just reset the whole phone and follow your instructions again. I will report back when I get around to that.

Ok, I decided to play around a little before trying a reset; and I installed Viper 4 Android legacy with the APK from the zip you gave me, and it now says audio format supported! Yay! It just says "Processing: no" now. I have a feeling that I have something setup wrong. Any ideas?
Edit: Grammer

You managed to install driver v.2.5.0.5 or latest v4a?
Processing should change to "Yes" whilst audio is playing (music player/ YouTube/ system sounds etc).
Streaming music can be hit & miss; set up Audio Compatibility Patch correctly (via Magisk).

I installed driver version 2.5.0.4 with the APK you pointed me towards in the .zip/viperfx/app folder.
I will reinstall the audio conpatibily patch. What options should I choose in the patch?
Edit: I did not install the driver *with* the APK, but alongside it. I installed the driver via ViperFX Legacy in Magisk.

Try the ACP if V4A not working for streaming music apps.
I selected following:
- Skip audio_policy patching? = NO
- Skip notification_helper remover? = YES
- Skip usb policy patching for usb dacs? = NO
- Use lib workaround? = NO

That's fine, as long as V4A driver is enabled/ status normal/ format supported/ and it is processing during audio play.

It still isn't processing audio : (. I have tried resetting and following your instructions again. The only way I am able to get it to stop displaying "Status: Abnormal" is by installing Viper4Android FX Legacy in the new driver mode with the user app, then installing the Audio Modification and compatibility patch, then restarting and installing the APK you gave me. Even with all that, it will not recognize audio being played (it displays "Processing: No" when audio is very clearly playing and I have effects enabled). I am now considering switching to LineageOS (I would be there already if it wasn't for the fingerprint sensor driver being broken).
Edit: Do you think switching kernels would change anything?
Edit 2: I noticed a toast notification from V4A on startup saying "A running program has requested Android to disable audio effects, so V4A will be temporarily disabled."
I am thinking that maybe the stock Dirac audio processing might be interfering with V4A somehow. Is there anyway to get Viper to ignore requests to disable?

Well, Lineage didn't fix anything (No matter what I did, V4A would not stop displaying abnormal). Took me a little while to get back to stock, but the latest version of V4A is working, but only for the first 30 seconds after reboot before giving me the previously mentioned toast notification. I have removed all apps that are even remotely audio processing related, but still have this problem. Anybody else had something similar? If you did, how did you fix it?
(Also, special thanks to elmor0 for all of your help getting me this far I'm so close)
Edit: Holy shiz it's working! I used the method described in my previous post, but with the added step of uninstalling and reinstalling audio modification library after the last reboot. Again thank you all for your help! And I really hope this helps someone!

I'm having the same problem for months now
I hear it needs SE Linux to be permissive for V4A to work properly
I had no success on getting that SE Linux to turn Permissive unfortunately
long story short , I found myself here
can you please give me a step by step on how you got V4A to work , that is off course if its still working for you man
I'm at the end of my rope here , any guidance would appreciated ,
Thanx

First of all i want to thank you for the clear and detailed guide...
i have few questions tho, is there any way to install without switching SELINUX to permissive?? my concern here are the security issues
also can i add ainur narsil along with V4a, or is it even worth it?! if yes then what the installation process would be??
thank you in advance!

Unfortunately viper doesn't work properly without selinux permissive.
You can try different sound modes. however, problems occurred when I tried it on pe +. Also I don't think an extra sound mod will be needed after making good adjustments with the viper.
