If you're like me and finally got V4A running successfully but didn't hear it affecting the actual audio output then try this script I used to use on my LG G4 successfully. Make sure to set it so its ran at boot and PROFIT! It worked for me! You have no idea how I'm excited to finally have V4A back and working now on my V10!!

Alternatively you can DOWNLOAD the script I exported, and import it using the app of your choosing. I recommend using ROM Toolbox.
Here's a quick step-by-step of how I got V4A running on my rooted Verizon LG V10 for those of you who like that sort of thing.
1. Go into SuperSU and disable namespace separation in SuperSU.
Thanks to gerry_753 for this tip.
2. Reboot.
3. Download and install this BusyBox by JRummy and install BusyBox into both system/bin and system/xbin.
4. Reboot.
*5. Download and install SELinuxModeChanger.
*6. Open SELinuxModeChanger and change the SELinux Mode to: Permissive.
7. Download the latest Viper4Android and install it.
8. Open V4A app and install the driver.
9. Reboot.
10. Open ROM Toolbox and make sure to give it Root permission.
11. Scroll down and select Scripter
12. Hit the + at the top and select Import
13. Find the Viper4Android_Script you downloaded and click it.
14. Now click the Viper4Android_Script and select Set at boot
15. Reboot.
*Indicates steps I didn't take to get mine to work, but others have had to take in order to get it to work.
Still haven't noticed a big increase...but things look correct after running the script.
The script didn't work for me
add app to system priv/app
Thank you.

THANK YOU!. These specific apps and these specific instructions worked perfectly the first time.
I can tell the difference and it's great. Still can't quite make out the difference with the LG HD Dac drivers, or whatever it's called. seems to help a little too...maybe I have to research how to fine tune that, if possible.
Thanks again.
Got everything installed and ran your script. Much like the picture above it says it's installed but it's NOT prcoessing. I can use the equalizer app from the market and that works fine but viper is still a no go. Such a disappointment.
I tried everything, installed busy boxes, have it permissions, paid 5 bucks to get the full version of toolbox to add program as a system app. Restarted i don't know how many times. Almost as painful as getting to work on my old fascinate was.... Any thoughts?

Looks like its a music app thing, I use Spotify primarily which doesn't like to work with 99% of equalizers.
Viper4Audio DOES work with local audio as well as googly player and others the same that the HIFI DAC does. That doesn't work with spotify either and its a known thing. Basically I can trick the phone for a single song by playing a song in google music's app, then changing immediately to spotify. But after the song is over it stops amping the audio. So the issue is spotify isn't taking advantage of the audio on its own. I think they need to fix this because spotify was the only reason I stopped downloading music. But seriously, I'd pirate my whole music list again just to have it usable in the player with viper.
So as far as I can tell spotify users you are still SOL. I recommend "Equalizer" from the market place as it does work. /wrist

Hey @R4NDR01D, can I disable the ROM Toolbox Lite from start up after application of the script or do I need to have it on to "enforce" the script? I like to disable things from running booting up if they aren't absolutely necessary. Thanks

What do you have enabled? (Obviously) Make sure V4A-FX Powered on is Enabled, then below is the settings I've found work best for me:
Firequalizer: Enabled
Select Preset: Rock
Dynamic System: Enabled (Left everything else alone)
ViPER Bass: Enabled
Bass Mode: Natural
Frequency: 60Hz (Sometimes 80Hz)
Bass Boost: 6.0 dB
ViPER Clarity: Enabled
Mode: Natural
Clarity: 3.5 dB
CureTech+: Enabled
Binaural Level: Slight
Anything with built in equalizers (like PowerAmp) will often muddle the effects of V4A. There's ways around this. But I use purely Spotify these days and have noticed vast improvements using V4A now.
Also, if ever want to dabble with Convolution, Viper has a great IRS starter pack and explanation on his site. Supposedly you can bypass all my above settings by using just one IRS sample. But I've usually used them in combination with.

I can confirm on my end that V4A works with Spotify (at least via Bluetooth). It's the only player I use and there's a HUGE noticeable difference when playing a song on Spotify and enabling and disabling V4A.

Yeah it works on bluetooth great which is unfortunate because my car isn't bluetooth, nor do i want it to be. On the other size the DAC fix makes it work on heapdhone jack and that can be used with equalizer app from the market so I still have that. It's not viper4audio but really bluetooth is the only thing that really needed it. I'll accept that.
OP's instructions are spot on. Works with Tidal well. Thanks
What about youtube and system notifications/ring tones? I have viper4android working, but it only works for my music player. I'm hoping to get it to work system wide so I can tweak the horrible speaker when a notification comes through. Per this post: http://forum.xda-developers.com/showpost.php?p=65506006&postcount=3
He was able to get it to work system wide. I don't know of a way to flash a zip file without a custom recovery. I have viper4android as a system app and it's still not processing audio system wide.
I tried editing the audio file that edits the deep_buffer variable to allow v4a to work without headphones but it doesn't. BUT I don't think this is truthfully the case. On a fresh reboot upon opening spotify with headphones then playing a song and THEN opening viper, it gets HELLA loud for just a split second, which means that it did try to edit the live audio but failed and likely crashed. The question is, why? What exactly is going wrong with the headphone out on spotify. Literally the only app on the market that directly works with spotify is called Equalizer. I tried equalizer pro which is even better as far as mutliband control on a local player but it doesn't effect spotify either. Just Equalizer. So I'm curious what the hell that app is doing differently.
Thank you, it worked!
I created /system/su.d directory with execution permission, and added the shell script to that directory, with execution permission. In my system, the path to supolicy was different, and I corrected that. It worked like that.
Shortcut?
The only thing I needed to change was the selinux mode to permissive and V4A works perfectly now.

Viper4Android works fine on Gingerbread, as long as you use the v2207. Any version above that only works on JB.
If you want, I´ll upload you that version tomorrow...
Please give me the instructions too! I really dont know why is there two apks (FX & XHIFI) !!

(NOTE: XHIFI never made the sound on my phone better, so this is originally for the FX version, even though it works also with XHIFI. Anyway, the FX offers the most options and best sound effects )
1. Extract the apk onto your sdcard
2. copy it to /system/app
3. Reboot
4. Open Viper4Android FX
5. Grant SU permission
6. Install drivers
7. Reboot
After that, you can customize the settings to what sounds best!
Oh, and don´t use the convolver, it either makes your phone laggy or initialises "akward restarts" .
Can you upload ViPER4Android Audio Effects v2207 ? I really cant find it!

Have you ever tried Mixzing music player 2.7.1? The EQ of mixzing is good, but don't know if better than Viper4Android in Quality.
Does this Viper4Android make music play with more quality? By quality i mean the sound is sweeter and the vocals are higher 'because normally without EQ vocals can hardly be heard, specially on rock songs'.
I tried many apps but none has made vocals become Clear and High to be heard good.
is Viper4Android worth the try for this?. If yes, can you show me your settings to achieve such good sound 'you can take a screenshot and put it here'?
Thanks btw

I did it all, well the effect was a little bit aggressive for my earphones xD but i changed it a little bit so there is no problem xD.
The sound looks like it become a bit more 'rich', but never more 'clear', so i guess there really is no way to make the vocals sound clear and high xD. Anyway i'll keep your effect 'modified' and test it more days, at least the sound being more 'rich' is also an improvement i think xD.
Thanks bro

i don't see any option with the name 'clear audio', so i supposed that was on XHIFI version, i installed it but there's no option with that name either :S xD. What is the real name of the option you're talking about? xD.
After testing today the yesterdays effect of viper4android, i noticed that audio actually got a bit worse and not rich :S , and if i use your headphone effect 'so much bass' then the vocals are even lower than normal :S . So maybe that Clear Audio thing you mentioned can solve this problem i think xD.
Ps: i'm using 2207 fx version. when i installed xhifi 2100 version the option Audio Reconstruction is very very laggy in the sound when Enabled 'looks like the sound is having hiccups all the time xD', i don't know what the f... is happening with this ViperFx thingy xD, having good sound quality is a total Headshot xD.

As said before, the audio profile I posted works best on versions above 2208. When not used on versions above that, the options 'viper bass' aand 'viper clarity' aren't available, which basically defeats the reason to use that profile.

I knew the name was wrong xD. Yes i saw that but you also said that versions above only work on naa-06 kernel and if i'm not wrong there still isn't any rom completly Stable on that kernel , so i guess that viper4android will have to wait because a stable rom is more important than increasing audio quality :S . I tried version above 2207 and the result really was strange bootloops and i had to Restore a Backup of the Rom on CWM :S . But thanks anyway bro .
Ps. Well, i started another thread in this Help section xD, it's about the Text Selection, if you know how to solve my question about this let me know in the thread bro.

Viper4android makes the sound so much better when listening to music on my stereo system, through my phone. However, it seems to only work about 1/3 of the time. Sometimes it will be working, then I'll select a new album to listen to, and it no longer works... And vice versa. Sometimes it just will not work at all, even after a reboot. It's just completely random. I'm running it on a VZW Galaxy S4 with the Hyperdrive Rom installed. I would love to figure out how to get it to work 100% of the time.

You got to be rooted and have SuperSU and BusyBox on your G2. It's reported that SuperSU plays nicely with ViPER4Android and Superuser could have some difficulties.
App will install drivers for you and make sdcard/ViPER4Android/Kernel folders in your main storage. Follow instructions from the app. Basically, just pick desired audio quality / battery consumption. Reboot. If ViPER4Android folders are not automatically created, see EDIT at the bottom of this post.
In sub-folder named Kernel extract IRS files from attachment (at the bottom of this post) or downloaded Starter Pack from OT. Reboot again. In order to see Convolver / Impulse Response (IRS) files, go to UI Setting and choose Expert option.
I removed some IRS files from original starter pack and cherry picked some more free IRS files from other packs.

Don't be afraid to install because description is in Chinese. If you want translation you could use desktop Chrome browser to translate into English. After installation everything is in English.
App will install drivers for you (G2 use CortexA8 with NEON) and make 2 folders in your SD card. Follow instructions from the app. Basically, just reboot. In sub-folder named Kernel extract IRS files from attachment or downloaded Starter Pack from OT. Reboot again. I removed some IRS files from original starter pack and cherry picked some more free IRS files from other packs.

I StumbleUpon it. LOL. Yes, you can change settings on the fly. So much to explore and experiment. Don't be afraid to change some settings but be careful with volume control. Start with 40% and don't go over 50% in first couple of hours because some combination of settings will give you volume boost up to 8dB. Maybe even 10dB boost. I set speaker settings with 8dB boost so watching YouTube videos with 30% volume feels weird at first. Still exploring. Probably it will take days before I become familiar with every option.

In the FX app, make sure convolver is ticked. Then press impulse response and it will tell you the folder is empty. It JUST created the folder you are missing. Go back to your file manager and copy the files there.

It's a lot louder lol
w000000000t!!
I was hoping there would be a sound enhancement for the G2 as I used nexus louder/noozxoide pro with my Gnex and it completely transformed the listening experience. I tried noozxoide pro with the G2 with so-so results so I'm excited to try this out. Thank you!! :good:
mine wont change. in driver status menu it says neon enabled: yes
enabled:no
status normal
processing no
i have v4A speakerfx is powered on checked
convolver is enabled checked
and xtra-loud is enabled check
i can also change the files in impulse response but nothing seems to change the sound at all.
im not a noob lol but this is new to me in all my hacking days.

I installed this jewel app on G2 last night and I'm still in awe. ViPER4Android is just amazing experience for music lovers and greatly improves performance of our DAC. Original thread in Development and Hacking received more than milion views and OP did amazing presentation in first couple posts.

You got to be rooted and have SuperSU and BusyBox on your G2. It's reported that SuperSU plays nicely with ViPER4Android and Superuser could have some difficulties. You can install app(s) in couple ways and I chose easiest for me. Play Store.
Link https://play.google.com/store/apps/details?id=com.vipercn.viper4android4x
Don't be afraid to install because description is in Chinese. If you want translation you could use desktop Chrome browser to translate into English. After installation everything is in English.
App will install drivers for you (G2 use CortexA8 with NEON) and make 2 folders in your SD card. Follow instructions from the app. Basically, just reboot. In sub-folder named Kernel extract IRS files from attachment or downloaded Starter Pack from OT. Reboot again. I removed some IRS files from original starter pack and cherry picked some more free IRS files from other packs.
Play Music and Shuttle+ works with default Normal setting. If you have problems with some other music apps try switching to back and forth with Compatible mode. Much more detailed instructions and explanations you could find in original thread.
Link, again http://forum.xda-developers.com/showthread.php?t=2191223
I believe that's it. Enjoy!
P. S. I can't attach right now because I'm using Tapatalk 4. I have option to attach a picture, not a file. I'll try later with something else. Use Starter Pack and(or) other packs. You'll find links in original thread.
EDIT; I attached zip file.

Thanks for the heads up on this Viper app. I will definitely try it out when I get my G2.
I am just curious if you ever did the "Increase Speaker Volume" fix in the thread below on top of installing ViperAndroid. I wonder if the combination of both the fixes will make the G2 speaker even better.

Can you tell any significant difference in the max volume when using sound "mods" like this?
What kind of difference can you see in the following scenarios:
1.) Stock Sound --> THIS Mod instead?
How about those of you that have been running Viper?
2.) Stock Sound --> Viper Mod ??
3.) Viper Mod --> THIS Mod instead ?

I'm using viper from the playstore and it works great for my music. I work in a factory and plug my 3.5mm head jack into a kicker stereo. The phone speaker it's self seems loud enough for me. No to knock this sound mod at all but I favor the eq in viper. Just my opinion. The only downside of viper is I have to greenify it when I'm done using it.

From what I've noticed about Viper is that it doesn't work with every music app.
It doesn't work with the Samsung music player.
It will work with the Google Play Music app with wav (flac encoded) files, but not MP3s.
It will work with Power Amp will all files, but the Power Amp trial app I downloaded can't see my wav/flac files for playback.

I have only been using it for a few days but my understanding is that replaces the stock DSP manager once you install the driver and select it in Settings > Music Effects, so the sound effect *should* be global and affect all music sources. I do not use the Samsung music app, and I do not store MP3s locally. I had some, but many of them must be inferior rips because they sounded flat or distorted no matter what EQ settings I used. I finally decided to try Google All Access, and I am glad I did. Using the highest quality stream and ViPER4Android, it sounds 100x better than my ipod.

The easiest way to know if Viper is working, is that when you are playing music, to go into the Viper app and uncheck the enable box at the top. If you hear the music volume/sound change, then you know it was working, and you can re-check the box.
I know that it doesn't work at all with the Samsung Music app.
On the Google Play Music, it does work with WAV( (FLAC encoded) files, but not MP3s. I don't have the "Google All Access" subscription, so I can't verify if Viper works with it.
Since my MP3s weren't sounding too good while using Viper, I got all my CDs and did them as WAV (FLAC), and copied it over the microSD card (but took about 21GB of space). But it does sound much better than the MP3 rips I did of these CDs many years ago.

I tried that while streaming Google Music, and it definitely makes a difference. I have no MP3s or FLACs to test with the Samsung Music app, so I have no idea if V4A effects will translate through that app.
Since using V4A and Google Music Service, I have heard new musical details (instruments as well as front/rear speaker isolation) on songs that I thought I knew very well. This is most likely due to the poor quality of my MP3s, rather than V4A or the quality of Google Music, but it was a nice surprise regardless. If you have not tried Google Music Service then I highly recommend it, especially if you are surrounded with solid 4G or WiFi. The first month is free. It's not on the same level as FLAC, but it will probably be a step up from MP3.

I downloaded the FX 2.3.1.1 version from the xda thread instead of the unofficial market link because (1) the market link is in Chinese, and (2) I wanted to make sure I got the latest release. Install it like any other apk, go to Settings > Sound > Music effects and select ViPER4Android. You will be prompted to install a special driver, so do that. Reboot, then open "ViPER4Android" in the app drawer, and tweak to your liking. Then play some tunes and adjust EQ and other options as needed. The effects are much more pronounced via the audio jack rather than the speakerphone.

I'm using 2.3.0.1 and it "automatically" installed the driver, as the one from the Play Store had a list of drivers, and I wasn't sure which one to use.
Does the 2.3.1.1 also automatically install the driver?
Edit: Updated to 2.3.1.1 without problem.
As is commonly known, at lower volumes the sound on the G pad is pretty dark and murky.
This can be improved easily by using an equalizer app and turning down the bass/lower frequencies, and turning up the higher frequencies.
I've tried a few different apps, some work, some don't.
Currently I'm using the "Music equalizer" app, which is allright but turns itself off after 30 minutes, so I'm looking for something better.
What apps have you found that work well with MX player?
(I know sound improves in other ROM's but I want to stay rooted stock, so custom ROM's are not an option right now)
Same here.
Today I installed DSP manager (from cyanogenmod).
Nice and exactly what I want, except that it doesn't work at all.

I use PowerAmp music player. It has a great DSP but I don't know if it works system-wide and I haven't really tried to find out because I haven't really though about it.
Upgrade to CM11, it will change your tab, especially concerning the sound..
Poweramp seems to be a music player rater than a generic equalizer.
About CM, have I mentioned in my start post that I want to stay stock, or did I forget to say that?

Greetings..
I know you want to stay stock but...
I was just reading this thread and I have CM-11 installed and I thought.. why not turn on Netflix and the DSP (which I was not using) and see if the DSP Mgr. does make a difference..
It Does.. A Big Difference if you adjust the EQ manually.. So at least you know you have an option should your situation become unbearable.
I know there is that option so I have considered that. Not having Qremote is not an option at this moment, so I'm not going there.
As for equalizers, I've found another one that works, but it also turns off after 30 minutes.
I have the impression that this is not so much a funcionalty, but a limitation within android.
Does anyone know if all equalizer apps will turn off after 30 minutes?
Does any app exist that I can use that doesn't turn itself off?

If you are rooted you could try AlsaMixer. It's kinda a carry over from Linux. Bear in mind that it had a major overhaul some time ago. It has so many settings for each connectin you won't believe it. Unfortunately I have no idea how to use it after the overhaul as everything is classified pretty cryptic, but I believe I saw something about 5 different EQ bands. AlsaMixer is system wide btw. The EQ is just one of many variables you can set. However finding a tutorial is imminent, if you ask me. Good luck.

I'm not certain of what I'm saying right now. But since MX Player is capable of using both software and hardware for both sound and video I suspect it may use it's own settings.. I don't know. I'm basing it on ZPlayer in the Market which I used for a long time, that one had it's own EQ and such and the dev said that the users shouldn't be using any 3rd party EQ's because it wouldn't have any effect.. May be some of the same stuff going on with MX Player since it offers all these different decoders.. Sorry, I'm not going back to stock to test this. Anything CM/AOSP related, I'll gladly check out for you. :/
I'm just wondering; DSP manager does not seem to have any effect on the sound of any apps here.
As for MX player (which is the only app I really care about for an equalizer to work with),
some equalizer apps work with it and some don't.
The few that I found that work all quit after 30 minutes, probably that's a limitation in android?
I'm starting to think harder about Mahdi rom, it sure looks nice but I just can't part yet from Qremote.

Thanks a lot for the suggestion.
Viper4androidFX works,
it works with MX player and it keeps working after 30 minutes.
I believed for a moment that this was the solution for optimizing the sound on the G pad,
however viper seems to have an unwanted effect on videoprocessing;
while streaming HD content over MX player there is a slight stutter in the video that immediately disappears when I turn viper off.
That makes useless for me really.
I am thinking about saying goodbye to the Qremote app and flashing Mahdi.

Some people can't make viper4android work on the new Lollipop update so I'm doing a simple guide:
Requirements:
-Root
-Busybox
-Custom recovery
Installation:
1.- Deactivate NuPlayer in developer options.
2.- Deactivate any other equalizer.
3.- Set selinux to permissive with an app like this one https://play.google.com/store/apps/details?id=com.mrbimc.selinux&hl=en
4- Install through recovery the zip located below then reboot.
5.- Open viper4android and install the driver you want and then reboot.
6.- Done, enjoy high quality sound.
these are the only versions of audio_effects and audio_policy i found that work with streaming apps. can you elaborate a bit more about them where did you find them or maybe you have an idea what was modified in them in order for streaming audio to work? thanks!
Good job! But how can I increase the power of the speaker, like in KitKat using Mixer app, but in Lollipop?

also, is the audio policy config on this thread flashable or pushable?

So, i've been having this huge problem on Nexus 7 2013 w\power amp and 5.1.1 cm12.1 and getting convolver and irs files to work properly.
two questions,
are your irs files working?
also, is the audio policy config on this thread flashable or pushable?

No problem with irs & convolver on my D802, both working normally. I don't know for other devices.
The file from op is flashable from recovery. You can try that.
Just for comparison, I use other methods, I installing v4a manually then install the drivers from the app. Imho audio effect config will change when v4a installing driver. Most useful part from this thread for me only the audio policy config that solve my problem make other apps like poweramp work with v4a. Then I found that audio policy config from D802 stock rom can be use too by removing 2 parts. I believe this solution is better because I only lost 2 features from stock rom, not as much as the policy config from op.

Yeah, i flashed the file above and did everything properly, but IRS convolver files aren't exactly being 'used', not all irs files are working properly.
Should i be doing anything to the audio policy config file ? I use power amp too (although it did tell me it was processing under power amp),
IRS is crucial to me because i use my N7 2013 in my car as my in-dash.

I think that's unrelated to the audio policy config thing, this thread already prove the way v4a working for D802. Solved the major problem why v4a only works for stock music & video player.
I suggest you to ask in the v4a main thread or maybe ask the dev that creates your favorite irs that didn't work. I only use 2 irs files & both working normally.
this is kind of off topic but perhaps somebody is experiencing the same. i'm having a weird audio issue on LP which wasn't present on KK in any way and not V4A related.
no matter what the audio source is (playing mp3s or lossless, tons of EQ on or off, YouTube video, game, video, etc) there's a totally random, short sound corruption that sounds like garbled, sped up noise. it's impossible to trace any pattern when and why does it appear and perhaps it's related to radio since it tends to appear more when the signal is switching from Wi-Fi to cellular or cellular signal comes online, etc but not necessarily. i tried to look at the logs and don't see anything suspicious regarding sound there at all.
there's also a theory on other devices forums that Qualcomm's mpdecision is the cause since it always leaves only one core for the sound online and on LP apparently you need more. that doesn't seem right, however, since it does happen when the phone is doing a lot too and not just with the screen off.
any ideas are welcomed.

You can try if the theory was right or wrong by temporary disabling mpdecision. I think the setting is in /mpt/enable file. Change the value from 1 to 0, than compared the results. Don't forget to enable it again by changing the value on that file back to 1. If still no different, I guess the theory was invalid.
doesnt work for me I flashed the zip and then got "viper 4 Android stopped working" on Start, now I cannot install it in the normal way. Every Reboot that "viper 4 Android stopped working" thing comes and idk what to do

I use those 2 files from the zip file to make v4a works for poweramp
My previous v4a installation only works on stock music & video player, now works for poweramp and mx player too.
Another note, disabling NUplayer not necessary for me...
Thanks again for this awesome guide :good:
Edit: I found using stock audio_policy.conf is possible to by removing this 2 sections:
1. Compress offload
compress_offload {

flags AUDIO_OUTPUT_FLAG_DIRECT|AUDIO_OUTPUT_FLAG_COMPRESS_OFFLOAD|AUDIO_OUTPUT_FLAG_NON_BLOCKING
}
2. Deep buffer

after much experimenting i can confirm that the only way to fix that issue is to always keep 2 or more CPU cores online, nothing else solves it at all.
with stock kernel the only option is to disable mpdecision and enable "multicore power saving" and "soc temperature throttle" for further heat control because without mpdecision you'll be keeping all 4 cores online.

Ah i will try that, Iam using dorimanx.
Did you get convolvers to work? They dont have any effect for me. Also the effect of viper4android is very small on lollipop. I can hear a difference but its nothing compared to kitkat

I had someone trouble getting convolvers to work as well. Converting viper to a user app with titanium uninstalling the driver then reconverting it to a system app worked for me.

after converting back to system app you install the drivers again or when its user app?
Edit: it worked! Iam using it as user app and its working flawless! Kudos to you

obviously using a custom kernel gives way more options to keep those 2 cores online in less destructive manner.
no problems with V4A here, everything works exactly like on KK. like mentioned above the key is to use it as a system app, modify selinux mode and edit audio policies files.
