[GUIDE] [ROOT] Install ViPER4Android on Nougat - Nexus 6P General

I heard that there is a lot of confusion about installing ViPER4Android on Nougat. After searching around the web i found a way to do it ^_^ It should work on all Nougat build released until now. Last test on N4F26J
First of all unistall any previous ViPER4Android app.
Requirements:
Root
TWRP
SuperSU 2.78 or higher
BusyBox 1.24.2 or higher installed in \su\xbin
Installation:
Flash ViPER4Android_2.5.0.5_guitardedhero.zip in TWRP
Go to vendor\etc and remove/rename audio_effects.conf using any file manager with root access (ex. Root Browser)
Open ViPER4Android app and install driver (Grant root permission). (It could freeze for a few seconds, just be patient!)
Reboot
Disable MusicFX app
Reboot
Done :3
I hope this will help you
Thanks to guitardedhero for the modified zip file
EDIT: fixed google drive link

ElementalX kernel not required. Thanks for the guide.... Enjoy

Magisk + V4A Add-on is how I use it flash those in twrp and then install v4a apk no editing system partition and you can install ota updates then just boot twrp and flash magisk again

---

I want to know if its working system wide.

---

viper4android saying not enable and not processing....anyone with the same issue?

---

for me its only working in compatible mode.. anyone else?

---

Did not completely work for me. At first when i did the procedure everything was ok,driver installed neon,ok. But when i played native audio or pandora no difference. Also when i plugged in my Fiio K1 DAC it change to not supported abnormal. Tried clean installing into system 3x, edidtin,deleting, the file in vendor. No luck, maybe we just have to wait a bit longer, rom used is Purenexus. Also when i did it,i already had the drive installed.....

UPDATE:
So i did get it working, but i used the Viper 6.01 that guitar user posted in the nexus 5x forum.
Works with only Headphone jack,
NOT with usb out. When using USB out it just dosent work.
Also for some reason my pandora now keeps crashing
BUT IT WORKS, so i think ill keep it. Ill leave the DAC/AMP at home for my laptop, and use the viper limiter at maximum and just up the bass a bit.
All i wanted was to get the bass higher with out maximizing the volume.

Id suggest using arise, it's way better than stock Viper

If I may make a suggestion that will ultimately save you a lot of grief, move to the updated ARISE sound mod by guitardedhero and others. The latest is deuteronomy 2.x and, as opposed to the tweaks, futzing and issues of sound being processed/sticking or not, this is a much simpler install and just works.
Head over to http://forum.xda-developers.com/android/software/r-s-e-sound-systems-auditory-research-t3379709 and just install the base version. You'll get Viper4ARISE. I still flash a permissive kernel zip with my Nougat ROMs, but since I switched to ARISE, V4A has worked flawlessly, and it sounds even better than the old V4A from this thread.
It also removes MusicFX with the install process and I haven't had to disable/remove the audio_effects.conf file either.
Lastly, I'm not sure development is continuing on the base V4A anyway. ARISE is the way to modify your Android sound processing now.

I amd a bit confused. So i still need to flash a kernel zip besides the ARISE file? I am on 7.1.1 preview with stock kernel

You don't need to AFAIK and it isn't a kernel. V4A used to need SELinux permissive to run, but stock and most custom kernels run enforcing. I just mentioned that I flash a permissive mod out of habit FYI. You are likely better off going to the A.R.I.S.E. threads to discuss issues.

Just flashed Deuteronomy 2.1 (non classic) on my nexus 6P. After enabling V4Arise and enabling speaker optimization, the phone speaker sound is actually worse than stock, more muted across range. I haven't tried headphones yet. kinda disappointed. My advice: V4A is overhyped. just keep stock sound.

Sorry, but you clearly haven't tested anything at all yet. Speaker optimization isn't that great and yes it mutes it, but that's to avoid the pop and tinny issues with many phone speakers. However, if you use that, then play with the EQ and other settings, you may surprise yourself. That would require more than a 5 second evaluation though.
Have you tried the EQ presets or customized them? What about dynamic sound or the various compressions? How about any number of things most people would play around with before writing something off? These types of tweaks are, after all, the point of a sound mod with a detailed EQ.
Since you admit you haven't even tried headphones, let alone bluetooth and haven't played with the EQ at all, it may just be a wee bit early to pronounce it a failure. And ... the VAST majority of people who use it would disagree.

What's the point of installing it if you have to do all the work yourself in that department? I'm not an audio engineer, I don't know what is best for my phone.

Exactly. If regular people have to spend hours or days to tweak the settings what's the good? I wish it's the install and forget type of app.

Worst part is I've had hearing problems since I was an infant, so like, i can't really test settings and **** since I can't really tell the difference incrementally.

Hours or days? It takes me a few minutes of playing on a fresh install until I hit what I like. Plus, you can save your settings as a profile. However, it's clear from your responses that you can't be bothered to actually test it. If you have a home stereo, you play around with EQ until you like it. If you listen to music in your car, you set treble and bass, balance and other things. This is no different. How on earth a sound app that, at its heart is an EQ, could be set and forget BEFORE YOU INSTALL IT is beyond me. That's not even the purpose of it. If that's what you want, then you're not looking for a sound mod. The entire point of a sound mod / EQ is to allow people to adjust the sound to their preference for their hardware and listening preferences/context.

ultyrunner is absolutely correct here. The criticisms you have leveled against this project would be considered rude (and a bit ignorant) even if you actually had a solid point to make, or some evidence to back it up. As it stands, you don't have either, and asking a question like "What's the point of installing it if you have to do all the work yourself in that department? I'm not an audio engineer..." is just unthinkable. People specifically poured blood, sweat, and tears into this thing for that exact reason... so that people who aren't engineers can improve their experience via the developer's knowledge. Either you were just being flippant about "having to do all the work yourself" and you don't actually mean that - in which case it would have been preferable for you to just say "thank you but I am having a few problems," et cetera, and be on your way...OR you do actually think you're doing all the work, which is a smack in the face to a developer... a developer whose work you very obviously do not grasp the complexity of, nor the amount of time and effort required to produce said work. Don't bash people's work if you haven't yet evaluated it properly, and most especially make an effort to understand it at a high level before you complain (if you really need to complain at all, which you don't).
I'm sorry, but if I was the developer, seeing a comment/comments like these would be enough for me to close down the project ASAP. And I'm not just pulling that out of my ass, I've been through five or six phones and development communities here on XDA, and I have seen exactly that happen on more than one occasion.
