Viper4Android NOT Working with ROM(s)

Viper4android isnt working.
1.Not working on both iNTrinSic and Negalite ROMs
..........The settings do nothing. And for some reason I didn't get any audio filters. "Impulse Response"...so i downloaded them and placed in the right folder...toggle through them with nothing.
3. Current setup is iNTrinSic 8/6 build...comadose...7/24 KT Kernel..with newest Viper4android build installed as a system app...with proper drivers installed
4. Driver Status looks normal except for "Processing" says "no"
5. Tried the safe mode/fx compatible mode/reinstalling drivers/tried multiple music apps

Have 2 music apps installed, such as play music and stock music player start a song on 1 player and interrupt it with a song on the second player...Then viper will work with the player you interrupted it with...If this doesn't work reboot and try again...You will have to do this after a reboot or powering off, but you will be good other than that...

This has worked for me, though I never realized what i was doing. On another note, get a root browser of your preference and make sure the viper APK is in /system/app and not /data/app. I forget what ROM I was on at the time, but after struggling to get it to work to no avail, I realized the dev put the APK in the wrong place. Odd thing is, it would work sometimes, I think with the above method, then it wouldn't. It's a fickle beast on our devices, hopefully subsequent versions of the software should be more stable. It's annoying, but Viper is AWESOME when it works. Slightly off-topic, but the HTC One X Beats IRS is the best if you really don't know what you're doing with the settings, and for someone mildly familiar with the other settings like myself, it's still a good overall foundation to tweak from. Happy listening, hope this helps!

Viper works just fine for me on both of those ROMs, I am however using Poweramp. Although it also works with stock music app and MX player pro also. I have purchased two of the .irs packs also and these work just fine too.

I was having trouble getting Viper4android to run correctly on my TouchWiz Rom too and here is a solution that works:
Download Build Prop Editor from Play Store.
Launch Build Prop Editor and change the following lines if they exist:
Ipa.decode=true to lpa.decode=false
tunnel.decode=true to tunnel.decode=false
lpa.use-stagefright=true to lpa.use-stagefright=false

[Q] Rick Rom issues

It sounds like you didn't enable it correctly. It works fine on my phone. Did you open Viper and install the driver in super high quality and enable it? You also have to select it in settings/sound/music effects. Also it might not work with the samsung player but this is a Viper issue not the ROM.

Every time I open it it ask to install drivers I enabled it and turned it on in settings

That's strange try clearing the cache in the application manager for Viper also if you haven't update supersu. You will be better off flashing the update in safe strap.

This maybe a dumb question but what file do I need to upgrade binary on su

One last thing. Go here and download the latest Viper4Android FX, FX version v2.3.3.0. Extract the zip and copy ViPER4Android_FX_A2.3.apk to your ext SD card and reinstall the app. Don't use the ViPER4Android_FX_A4.x.apk file it will force close. That should do it. If not try a clean wipe and reinstall the ROM to the stock slot. I know it's a pain but other than what I suggested already I'm out of options. I have no idea why it's giving you a hard time in the first place.

Thank you that worked thanks for your time

How I passed safetynet, got root, adblock and viper-fx to work on OOS 4.0.2 OP3T

I decided to start this thread for a couple of reasons 1 so I can remember what order I did things in to get back after a wipe and 2 so maybe it can help others to setup certain apps how they want and not have to spend the time I did searching and googling.
To start we are going to assume you already have an unlocked bootloader and TWRP installed.
After a fresh wipe I flashed OOS 4.0.2 Full from this thread in TWRP
https://forum.xda-developers.com/oneplus-3t/how-to/rom-oos4-0-nougat-op3t-leaked-t3523482
I recommend a fresh wipe because every time I did a dirty flash or restored a backup my Android System started draining battery like crazy and phone would get warm while charging
Without rebooting I then flashed Magisk V10.2 in TWRP
https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
Still without rebooting I flashed Franco Kernel in TWRP
https://forum.xda-developers.com/on...ernel-franco-kernel-r1-28th-november-t3508904
I then wiped dalvik and cache and rebooted phone.
edit - THIS STEP WILL NOT WORK ON 4.0.3. It has been patched out.
Somewhere in the process my DM-Verity was tripped and although annoying it does not seem to matter and it can be fixed later by following this
https://forum.xda-developers.com/oneplus-3/how-to/fix-easy-method-removing-dm-verity-t3544339
After phone booted and I setup account and wifi and I go the play store and install PHH superuser
https://play.google.com/store/apps/details?id=me.phh.superuser&hl=en
Once installed I open it and click the 3 dots and go to settings
Where it says Superuser access I toggle between Apps only and Apps and ADB till I get the message Superuser granted to Superuser
I then go back into play store and install Magisk manager
https://play.google.com/store/apps/details?id=com.topjohnwu.magisk&hl=en
I go into Magisk Settings and click the checkbox to Enable Magisk Hide.
I then reboot phone
Once phone reboots I open Magisk manager again and check safetynet. It now passes.
I hate ads, I had been using Adaway from F-Droid with MM but I couldn't get it to work on N
I found this https://github.com/AdAway/AdAway/issues/770 after many searches. About halfway down a user named KreAch3R has comiled Sanjay900's changes into an apk so I figured I would give it a try.
At first I could not get it to activate and block ads
I installed this busybox and then it activates no problems and now most ads (not youtube) are blocked
https://play.google.com/store/apps/details?id=stericson.busybox&hl=en
Now what I really wanted was Viper4arise. I tried flashing some in TWRP and I couldn't get them to work and this led to a couple more wipes. But I really wanted this so I kept searching.
I found this https://forum.xda-developers.com/apps/magisk/viperfx-mkm-magisk-t3535401
I downloaded it and enabled it in Magisk manager
Still no luck and I couldn't get it to work.
After more googling and reading through the other threads for viper I figured it was deep buffering
I used ES file explorer as I was not at home and went into system/etc and found audio_policy.conf
I commented out the first line I saw that said deep_buffer.
After saving I rebooted and now Viper-fx works
To get it to work with Poweramp I had to set FX compatibility mode in Viper to compatible and in Poweramp audio/advanced tweaks I had to disable Direct Volume Control and Enable MusicFX.

Thanks for sharing

Did you have any special trick to get viper to work ? Tried commenting out the line deep_buffer and still unable to get viper to work.

Edited: Didn't see the attachment earlier. Answered my question. Thank you btw for sharing this the rest of the steps worked great for me. I am passing safety net.

Ya I realized a SS might help more so I edited it in.

Would you be able to send me that file ? I am just curious what is wrong with my setup.

Just want to say thank you again. Didn't see the PM until now. I was able to use another guide on XDA to get Viper working.

Viper will not work on all apps at any time on OOS 4.0.2. Enable Compatibility mode in settings to get it to work. IMO this produces lower quality audio, but it works.

Still cant get viper working. Nothing of deep_buffer is commanded. Please can you share your audio_policy.conf?

1) With what app?
2) Did you enable Viper's Compatibility mode?
3) I've also modified audio_policy_configuration.xml to remove deep buffer. Messing with this file too much will break your audio though.

WHat app isn't Viper working with? Viper processes audio on a per-app basis, based on the audio buffer the app uses. Google Play Music, on Nougat, does not pipe through Viper even with modifications to the audio config.
Enable compatibility mode. At the moment this is the only way to get the highest compatibility with apps- like Google Play Music.

It's now working after disabling audio buffer. I use most of the times Spotify to listen to music

I followed same steps earlier. But my selinux is enforcing. I have to set it to permissive everytime on reboot. Permissive fix that comes with arise didnt work for me. Any idea..?

Do you think the Elemental X Kernel would be ok instead of franco kernel? Not sure if I'd get compatibility issues with any of this stuff. Btw not going to try to get adblock or viper fx. Also, do you wipe the system or just what TWRP has already checked?

Not sure. I know it all worked the same with stock kernel.
Normally when I need to wipe my phone it is because I have really messed it up so I wipe system and data.

Viper4Android Pixel 2 XL stereo speaker optimization profile (Android Q working)

Updated: OP contains instructions for Android Pie and below, post #5 has current instructions for Android Q.
Saw a couple Viper4Android threads, did not see much in terms of profiles for the 2 XL specifically. Just got the 2 XL coming from a 6P and there was a great profile to optimize it's internal speakers so decided to try out the mod for the 2 XL's speakers. Working very nicely.
Not sure if this will work with every ROM but works nice on Bootleggers (should work on any Pie ROM including stock) and thought I would share so more people could enjoy much improved sound quality. Makes rooting the phone well worth it.
Instructions:
After installing Magisk 18.1
Install BusyBox and run the set-up
Download the Viper4Android V4.1 (used Material theme) via Magisk manager
run the install process, select 2.5.0.4 material theme, install as system app, grand root access then reboot
Load the DorianX profile taken from the 6P. Just unzip then look over the extracted files.
Edited to explain further: You will probably need to individually place the "SRS Audio HD" IRS file in the Viper4Android Kernel folder and put the Profile folder in the Viper4Android Profile folder (using a file explorer to copy/paste the files). Once that's done, in the Viper4Android app under "Convolver", tap it and choose "impulse response file", You should see the "SRS Audio HD" IRS file that you placed in the Kernel folder, select it, tick the box next to Convolver to enable it. Under the main app settings you should be able to select and load the profile. If you did it correctly the DorianX profile folder should be visible to select it. It depends which version of Viper4Android you install. If you do materialized (2.5.0.4) the above should work. Let me know if any problems
Play some music. Toggle Viper4Android master power on and off under the phone speaker tab within the app then back to on once to enable it. Usually you have to do this to "officially" enable Viper4Android. If it's working you will hear the difference. Under the app settings you can verify that the app is processing as well under "driver status". Working with the latest Poweramp, Youtube, etc.
Credit to DorianX who made the profile. There are 4 profiles included to optimize specific bluetooth devices, headphones,etc but just using the internal speaker one (for now). Unable to locate the past post in the 6P forum containing the profile and which other devices were optimized to link to it.
Works very well and thought it was worth posting and making a small contribution so for now enjoy! Profile attached.

Have Viper4Android working nicely on Android Q Beta 4.
Those that downloaded this profile if you don't mind posting the Dorian profile speaker settings (all of them for each tab and whether enabled or disabled) would appreciate it. Profiles no longer can be loaded in this version of Viper.
Looking at the speaker xml file can see some of the settings but probably not all.
Magisk 19.3, Adaway works, viper now works all on today's beta 4. Tried all versions and combos. Getting the driver to install and stick was a big pain.Can post some instructions if anyone is interested. I'm sure plenty of people would like to get viper working.
Now if only Google apps like Gmail and Google play would be themed. Can see the force dark toggle is broken in this beta. Not sure if the Google apps were theming in Beta 3 or not.

See below

Ok I got it. No need to PM me the profile. Took most of the night but done now.
Would be unable to stay on Q without Viper4Android as well...
Make sure to uninstall all previous versions of Magisk and modules to start fresh.
Install Magisk 19.3 via twrp, install latest Magisk manager and then Busybox (make sure to set up busybox). Some are having problems with this Beta and Magisk so YMMV. Working well for me and no app lag.
On Pie in Magisk you should see Viper4Android 2.7.1 module as available
On Q it's not listed (for me at least) so get it from XDA labs.
Install Viper4Android:
https://labs.xda-developers.com/store/app/download/com.pittvandewitt.viperfx (link to direct download, must be signed in)
Or use this link: https://labs.xda-developers.com/store/app/com.pittvandewitt.viperfx
The installer will install it as a magisk module. Grant supersu permissions, install driver, phone will reboot.
Install the magisk audio modifications library module. Reboot. After rebooting disable this module (do not uninstall). Reboot again.
Open up Viper4Android. If it asks you to install driver again do so and phone will automatically reboot. Repeat if needed. If driver install remains unsuccessful try enabling and disabling the audio modifications module then try again. What worked for some worked the opposite for others in past threads on previous Android versions and various devices. Here is the thread for reference: https://forum.xda-developers.com/pixel-2/help/viper4android-driver-installation-fails-t3766362
Once driver is installed the app will load properly and under driver status it will probably say "unsupported" and "abnormal". Close the app
Go back into Magisk manager. Now toggle to re enable the audio modifications module. Reboot. (This is the module that allows Viper4Android to process and can help to install the driver)
Upon reboot, Viper4Android should work. Play some music, check the driver status to verify, you may need to toggle off/on master limiter to finally enable it.
For this profile, put the SRS file in OP above in the Viper4Android Kernel folder. Under the apps speaker tab manually input these settings:
Master limiter: On
Playback gain: moderate or 2, max gain 4x, output threshold -1.9db
FIR Equalizer: On. EQ is flat
Convolver: On. Tap convolver then select the SRS inpulse file you placed in the Kernel folder. Cross channel set to 0
Profit.
You can set or disable the viper4android notification icon in the statusbar within the app's settings.
Let me know how the 2 XL's speakers sound Post updated, instructions should be clear enough. Some having problems will need to wait for the updated Magisk. Moving forward, we do have viper4android working on Q. Fully tested on my 2xl and stable with beta 4.

succesfuly, ty
for my 2xl It was
1. installation from xda lab - reboot
2. install audio modification library - reboot
3. open viper (still asking to install driver - just close app, don't choose nothing)
4. go to Magisk switch off audio modification library - reboot
5. viper successfully load, status normal and working (media) with just my favorite profile no custom settings

Our 2 XL's can be temperamental, lol.
Glad you got it working. Not sure how the driver installed and the viper app fixed itself with the audio modifications module switched off. It's like you didn't need that module at all. Whatever works.
Just happy we have viper for Q. Played games, music, youtube and running stable here.

Good stuff. To anyone else installing viper just to note if you click on driver and see it as processing = no this does not mean you did anything or the install went wrong. Play a video or music, driver should show as processing yes. When nothing is playing then processing will be no.

Does this enable dual speaker for calls/message alerts?

How did you guys get magisk working on Q beta 4? For me it makes systemui not start on boot and it skips the lock screen entirely. And if it does boot normally, apps take over 10 seconds to launch. I have tried to wipe system data cache and then ran the flash-all bat and still have the issue. A lot of others have the issue on the magisk canary thread. Some don't have it. Someone suggested after a full wipe with -w it fixed it.

Looks like I found a solution that is working for several members (and it was purely by accident because installing Magisk threw an error). Uninstall Magisk in TWRP first then:

It's not working for me. I had to reboot about 4 times because systemui wasn't starting up and I was getting a black wallpaper with no status or nav bar. Finally rebooted normally and at times apps refuse to open but it's slightly better than it was. This is just so weird. Do I really need to wipe my phone or is it magisks fault?

Someone in the Android Q discussion thread might be able to help better. Google pulled the beta so it's tough to say whether in your case it's a magisk or android issue. Or both.

I love this post for real, I have a Pixel 3 with Android P, viper v2.7.1.
I had to port the userprofile to the new version, if someone want it, PM me

Feel free to post it as well. Curious how you were able to port the profile. Looked everywhere but couldn't find any info to convert the old profile to the new preset format.

Yes it did the same for me. The first time, almost forgot. I did not find the sound to be the same, not even close. Ultimately I still had my Nexus 6p and was able to retrieve the settings and input them manually. Then the sound was as it should be.
Do you find the sound identical with the ported profiles? It might be hit and miss.

Question about Viper

I use Amazon Music with Viper Mod and Dolby. The problem I have is when I start playing my music I have to go into the Viper app. As soon as I open the app Viper kicks in.
Is there something I can do to kick Viper in automatically?

Hi, re-instak and follow instructions, instal as system app, u mess a step

Honeslty, I have never been able to get Viper working fully on my 6t. You might want to try removing the optimization in settings to see if that will let the app continue running. I think OOS just disables it after you don't have anything playing for a while.

I mainly play on my car Bluetooth when I am driving mostly a volume issue but do like surround sound as well

Have you tried making Viper a system app so that the process won't continually get killed?

When installing Viper4Android 2.7 it doesn't give me any options just installs it, FX Legacy I can't seem to get to work

I moved it to system with terminal emulator so we'll see.

Install viper as a magisk module. Select as system app
Runs fantastic on my 6T

Viper4Android FX 2.7.1.0 doesn't give me a option to select anything, It just installs completely and then says to reboot. I downloaded App Systemizer (Terminal Emulator} and moved it to system and now you are right it is running fantastic.

As a follow-up, about a day after I had posted, my viper stopped working. So I deleted the plug-in in magisk, and reinstalled 2.7.1.0 fresh and it's been work ever since! I apologise if I came off flippant at all. Seems they changed / updated something and that had to be done.

No need to apologize after a few times of uninstall and reinstall I gave up. Between my Bose Stereo settings in my car and the phone settings I get really good sound so I'm good.
